Project Title:Injectable tissue-engineered bone for mandibular distraction osteogenesis in smokers
Investigator(s):Cheung LK, Zheng L
Department:Dental Faculty
Source(s) of Funding:Small Project Funding
Start Date:12/2005
Abstract:
The objectives of the present study are: 1. To establish a nicotine-induced compromised bone healing (NICBH) model of rabbit mandibular distraction osteogenesis. 2. To compare the differentiation and proliferation of mesenchymal stem cells (MSCs) isolated from normal and "smoking" rabbits. 3. To study the influence of platelet rich plasma (PRP) on MSCs isolated from normal and "smoking" rabbits. 4. To compare the influence of PRP, MSCs/PRP, and MSCs/PRP/bone morphogenetic protein (BMP) on enhancing bone healing in mandibular distraction osteogenesis of "smoking" rabbits. It is well recognized that nicotine has a deleterious effect on the human health in many aspects, one of them is that it can impact adversely on the tissue healing process after trauma and surgery. Thus the patients, who use tobacco products commonly as smoking, will be at a greater risk from bone reconstruction surgery. This study attempts to establish a reliable and repeatable NICBH model in rabbit undergoing mandibular distraction, which simulates the in vivo biological situation of light and heavy smokers having the same surgery. The individual MSCs, PRP and BMP have been identified to be capable of enhancing bone formation in mandibular reconstruction, it is reasonable to assume that they may speed up bone healing in the NICBH model. This study attempt to explore the potential of using PRP, MSCs and recombinant human BMP-2 (rhBMP-2) togather to enhance bone regeneration, and find a effective method to meet the clinical challenge of smokers who need bone reconstructive surgery by distraction osteogenesis.

Project Title:The effect of R.O.C.S (remineralizing oral care system) toothpaste on artificial caries like lesions: An in vitro pH cycling study.
Investigator(s):Itthagarun A, King NM, Rana
Department:Dental Faculty
Source(s) of Funding:Small Project Funding
Start Date:10/2005
Abstract:
Recent advances in the technique of processing microradiographs by computer-aided image analysis allow the mineral profiles of enamel lesions to be assessed with great accuracy (Strang et al., 1987; Heaven et al., 1990; Chow et al., 1992). It is now possible to measure small changes in these profiles following exposure of the lesions to demineralization and/or remineralization in laboratory models, as well as in the oral environment (Strang et al., 1986). Unfortunately, the comparison of experimental and control sections is hampered by the biological variation in the enamel itself, especially by inhomogeneous lesions, even when they are prepared under standardized conditions (Strang et al., 1986). Several research groups have developed a 'single section technique', mainly for the purpose of determining differences between pre- and post experimental profiles at exactly the same spot (Creanor et al., 1986; Mellberg et al., 1986; Wefel et al., 1987). Since thin sections can be repeatedly subjected to microradiographic assessment during or between experimental treatments, this technique offers the possibility of determining time-dependent changes in lesion profiles resulting from localized dissolution or deposition of enamel. It may thus help to resolve the mechanisms which underlie the formation of subsurface lesions and laminations (Driessens et al., 1986; Palamara et al., 1986; Sato and Yamamoto, 1986), and the effects of both caries-protective agents and inhibitors of remineralization. Ten Cate and Duijsters (1982) developed a so-called 'pH cycling model' involving tooth enamel and intra-oral-like conditions of de/remineralization solution, and pH ranges. This in vitro technique has been widely accepted because it can simulate in vivo situations more closely than traditional experimental studies. Since then, many researchers have adopted and modified such pH cycling methods to use in both enamel and root lesion experiments (Featherstone, 1983; Ten Cate et al., 1988; Heilman et al., 1991; Itthagarun et al., 1997). The version developed by Itthagarun et al., has been used extensively to evaluate remineralizing agents in toothpaste, chewing gums and lozenges (Itthagarun et al., 1999; 2000; 2004; 2005). Recently R.O.C.S toothpastes (Remineralizing oral care systems, DRC Ltd, Moscow, Russia) have been marketed for school children and adults. It has been claimed by the company that these toothpastes 'accelerate the formation of enamel' and 'primary caries focus is enriched with minerals'. The main active ingredients of R.O.C.S. for school-children are complex AMIFLUOR® (minerals) with fluorine and xylitol, while the R.O.C.S toothpaste intend for use by adults contains MINERALIN® and bromelaine, a source of calcium, phosphorus and magnesium. Currently, no published data are available in the English literature. Xylitol has been found to induce remineralization of demineralized enamel by facilitating calcium movement and accessibility (Miake et al, 2003). It also raises the pH of saliva and changes both the quantity and quality of saliva, thus aiding the remineralization process. Bromelaine has been found to provide an anti-inflammatory effect and has been used in medicine and in dentistry, following third molar extractions (Hotz et al, 1989) Consequently, the essence of the remineralizing concept of R.O.C.S. might be achieved by simultaneously supplying calcium, phosphate, and fluoride ions to the teeth in order to induce the formation of calcium fluoroapatite which remineralizes and strengthens the tooth (Torrado et al, 2004). However, as no evidence on the remineralization effects of R.OC.S toothpaste has been published in the English literature, it is appropriate to evaluate the remineralizing effects claimed and also to determine the mechanics involved. Objectives of the study: The aims of this in vitro pH cycling study is to use the single-section technique together with our modified pH cycling model to evaluate the effects of R.O.C.S schooldchildren and R.O.C.S adult toothpastes on the remineralization of enamel artificial caries-like lesions. Their remineralization efficacy will also be compared with that of a standard fluoride toothpastes intended for both children and adults. Key issues and problems to be addressed: Hypothesis to be tested o The new R.O.C.S. toothpastes for children will enhance remineralization of initial carious lesions in tooth enamel more effectively than non-fluoride child toothpaste o The new R.O.C.S. toothpastes for children will show similar 'healing' efficacy of the enamel initial cariuos lesions when compared to that of a standard fluoride toothpaste for children (500ppmF) o The new R.O.C.S. toothpastes for adults will enhance remineralization of initial carious lesion in tooth enamel more effectively than non-fluoride toothpaste o The new R.O.C.S. toothpastes for adults will show similar 'healing' efficacy of the enamel initial carious lesions when compared to that of the standard fluoride toothpaste for adults (1000ppmF)

Abstract:
Periodontal disease is a family of related diseases that differ in etiology, natural history, disease progression and response to therapy but they share a common underlying chain of pathogenic events (Page et al 1997a,b). Plaque-induced periodontal diseases have traditionally been divided into two general categories: gingivitis and periodontitis. Plaque-induced gingivitis is the presence of gingival inflammation without loss of connective tissue attachment, while plaque-induced periodontitis is the presence of gingival inflammation at sites where there has been apical migration of the attachment onto the root surfaces accompanied by loss of connective tissue and alveolar bone (Armitage 2004). The primary clinical features of periodontitis include clinical attachment loss, alveolar bone loss, periodontal pocketing, and gingival inflammation (Flemmig 1999). In addition, enlargement or recession of the gingiva, bleeding on probing, and increased mobility, drifting, and/or tooth exfoliation may occur (Page & Schroeder 1976). With few exceptions, most forms of periodontitis are chronic inflammation that may progress continuously or by bursts of activity (Socransky et al., 1984; Löe et al., 1986; Jeffcoat et al., 1991). Human periodontitis is initiated and perpetuated by a small group of predominantly gram-negative, anaerobic or microaerophilic bacteria that colonize the subgingival area (Darveau et al., 1997; Page et al., 1997a,b; Flemmig 1999; Corbet & Jin 2004). Indeed, at the 1996 World Workshop on Clinical Periodontics, it was concluded that most of the periodontitis is caused by Porphyromonas gingivalis, Tannerella forsythensis (formerly Bacteroides forsythus) and Actinobacillus actinomycetemcomitans (American Academy of Periodontology 1996). In the last decade, we have come to realize that, although bacteria are essential, they are insufficient for the disease to occur nor responsible to the severity of the disease (Page et al., 1997). Manifestation and progression of periodontitis is influenced by a wide variety of determinants and risk factors, including subject characteristics, social and behavioral factors, systemic factors, genetic factors, tooth-level factors, microbial composition of dental plaque, and other emerging risk factors. Host factors such as inheritance, tobacco smoking and various other risk factors may even outweight the bacteria as determinants of whether the disease occurs and of the severity of disease outcome (Kornman et al., 1997; Page et al., 1997b; Nunn 2003; Page et al., 2003; Persson et al., 2003a,b; Corbet & Jin 2004). It has recently been shown that variations in genotypes of inflammatory cytokines and mediators may be independent risk factors for severe periodontitis, such as IL-1A and IL-1B (Kornman & di Giovine 1998) in chronic periodontitis; and IL-1RN (Parkhill et al., 2000), TNF-A (Galbraith et al., 1998) and IL-10.G (Hennig et al., 2000) in aggressive periodontitis. We recently found that a single nucleotide polymorphism in the MMP-1 promoter region of –1607 bp may be associated with generalized aggressive periodontitis in Chinese population (Cao et al., 2005). In addition, the contribution of periodontal pathogens to halitosis has been established in many studies (Lee et al., 2003; Tanaka et al., 2004; Figueiredo et al., 2005). The relationship between obesity and periodontal disease has recently been reported in Japanese and American populations (Saito et al., 2001; Al-Zahrani et al., 2003). Thus, the concept of multiple periodontal risk factors may induce a great impact on the understanding of the etiology, pathogenesis, prevention and treatment of periodontal disease. Risk is defined as the probability that an event will occur in the future, or the probability that an individual develops a given disease or experiences a change in health status during a specified interval of time (Kornman et al., 1997). A risk factor is any characteristic, behavior, or exposure with an association to a particular disease. The relationship is not necessarily causal in nature (Brownson & Pettiti 1998). From periodontal point of view, that is any factors which increase the probability of developing periodontitis, or lead to a measurable change (tooth loss) in the status of the periodontal supporting tissues (Albandar 2002). It is clear that periodontal risk assessment is potentially providing profound social and economical benefits with regard to disease prevention and control. It would be of great value for better caring of individual risk patient and determination of community treatment needs (Attström et al., 1994; Albandar 2002; Nunn 2003; Asian Pacific Society of Periodontology 2004). It has been demonstrated that not everybody is at equal risk to periodontal destruction, despite inadequate oral hygiene and hence exposure to microbial dental plaque, because of different combinations of risk factors (Löe et al 1978a,b). Currently, risk assessment for periodontitis remains subjective, empirical and variable from one clinician to another and from one patient to another (Lang et al., 2003; Page et al., 2002; Persson et al., 2003b). Utilization of periodontal risk assessment system over time would probably result in more standardized and appropriate periodontal treatment plan, effective periodontal therapy and long-term maintenance care. The Periodontal Risk Calculator (PRC) (Page et al., 2002; Page et al., 2003; Persson et al., 2003b) has been developed and tested in USA and the Periodontal Risk Assessment (PRA) (Lang et al., 2003) has been proposed for clinical application in Europe. As a country has data on risk associations for periodontal destruction in its own citizens, it would be prudent for periodontal researchers in that country to construct and test the validity of an appropriate risk assessment model for clinical use in that country (Corbet & Jin 2004). As there is no such risk assessment system in Hong Kong, the present study is therefore to develop and validate a periodontal risk assessment system, i.e. Periodontal Risk Spider-web (PRS). Aims To build up a practical periodontal risk assessment system for the assessment of periodontal conditions as well as prognosis and estimation of treatment responses in Chinese subjects with periodontal disease. Objectives - To build up a risk assessment system. i.e. the Periodontal Risk Spider-web (PRS). - To validate the relationship between the PRS assessment score and the severity of periodontal disease. - To explore the possible linkage between PRS score and periodontal treatment response. Hypotheses - The severity of periodontal diseases could be assessed by the multi-factorial Periodontal Risk Spider-web. - Periodontal treatment outcome could be estimated by the multi-factorial Periodontal Risk Spider-web.

Sjögren's syndrome (SS) is one of the most common auto-immune disorders which affects 3-4% of adults, middle-aged women in particular. Major pathological changes involve lymphocyte and plasma cell infiltration of the salivary, lacrimal and other exocrine glands with progressive destruction of gland acini. The major oral complication of SS is severe dryness of the mouth (xerostomia) resulting in a shift of the oral microbial equilibrium to become more cariogenic, ie. increased level of Lactobacillus and Streptococcus mutans. Thus, SS subjects have a higher susceptibility to dental caries and early tooth loss. Objectives: 1. to quantify the colonization of Streptococci and Lactobacilli in whole saliva of SS patients 2. to identify, characterize and speciate the Streptococci and Lactobacilli species 3. to study the association of the level of salivary Streptococci and Lactobacilli species in of SS patients with concurrent caries status

Project Title:3 dimensional hard and soft tissue assessment of maxillofacial deformity in Hong Kong Chinese population
Investigator(s):Lo J, Wong M.C.M.
Department:Dental Faculty
Source(s) of Funding:Small Project Funding
Start Date:12/2005
Abstract:
Objectives 1. To acquire the 3-D facial norm value in Hong Kong Chinese Population. 2. To develop a 3-D soft & hard tissue assessment scheme for patient presented with maxillofacial deformity. Backgrounds Facial profile could be regarded as one of the most important concern of every single person. Maxillofacial deformities, which would distort upper & lower jaws’ relationship and facial profile, are reported to affect approximately 20% of the world’s population. Tremendous advances in the treatment of these deformities have been made since 1970s. Orthognathic surgery, specially designed for the correction of these deformities, is currently one of the most common practices in the field of oral & maxillofacial surgery. The success of the orthognathic surgery depends not only on the surgical techniques, but also upon an accurate pre-surgical plan. The traditional approach to a maxillofacial deformity involves clinical examination, plain X-rays, dental model surgery and videoimaging surgical simulation. Among them, the videoimaging surgical simulation could be regarded as one of the most important component. Apart from assisting surgeon to make an accurate treatment plan, this technique also tremendously helps the communication between surgeons and patients. In a study, 6-month after surgery in a non-imaged population, only 45% of patients reported satisfaction with the aesthetic outcome of their orthognathic surgery, whereas 89% of patients reported satisfaction with their aesthetic outcome after using videoimaging simulation in the same period. Outline of problem Despite the continuous evolution of technology, the traditional approach had several limitations: (1) The dental model surgery involves only correction of the occlusion only, while the correction of some additional skeletal deformity, including chin, mandibular border, gonial angle, paranasal, malar, and zygoma region, would rely mainly on intra-operative judgement. (2) Current videoimaging softwares share the similar limitation: the prediction is only limited in lateral profile only. Prediction of the frontal profile, based on the plain radiographs, is nearly impossible due to overlapping of the hard and soft tissue landmarks. Benefits of videoimaging technique are hence limited to cases presented with deformity in lateral profile / sagittal plane; while patients presented with problem in frontal / coronal plane could not gain any benefits from this technique. As a result, correction of any deformity in frontal plane, i.e. facial asymmetry, is depending solely on the model surgery and intra-operative judgment; and those patients are in lack any visualization of the change after operation. With the rapid increasing in quantity and quality, the worldwide Oral Health Care System becomes much more sophisticated. Patients’ demand on good quality treatment is increasing as well. The previous standard established since late 1980s, could no longer meet today patient’s expectation. Due to the complexity of the facial skeleton, current trend in surgical planning is moving from 2-dimension to 3-dimension. Past research in this field The use of 3D cephalometric analysis had been reported since 1996. Thereafter, a number of reports had been published. All 3D cephalometric analysis is based on measurement on CT scan. It is noteworthy that all the reports are consistent with the advantages in direct visualization of the hard tissue problem especially in patients presented with asymmetry. Regarding the soft tissue analysis, 3D soft tissue capture technique had been developed since 1996. The techniques included: morphanalysis, laser scanning, 3D CT, stereolithography, 3D ultrasonography, 3D facial morphometry, digigraph imaging, Moire topography, and contour photography. Recently, the use of stereophotogrammetry had gained popularity due to its fast capture speed as well as the photo-realistic quality. The application of stereophotogrammetry in studying asymmetry had been widely studied. Nevertheless, there was no literature regarding the combination of 3D hard and soft tissue capture, analysis and surgical planning. Situation in Hong Kong & Chinese Population The discipline of Oral and Maxillofacial Surgery, the University of Hong Kong, is the largest maxillofacial center in Hong Kong, and one of the most advanced maxillofacial center in Asia and the world. From 1990 to 2004, there were about 4530 patients received major operations from our discipline. Among them, 1455 patients (32.12%) received orthognathic surgeries for correction of their maxillofacial deformity. Majority of patients (60%) were presented with Class III deformity, while approximately 23 % patients were presented with deformity in frontal / coronal plane. Currently, assessment of the changes of facial skeleton could be achieved through plain radiograph and lateral portrait using our CASSOS system (Softenable, Hong Kong). Since every single patient would like to know what he or she is going to look like after surgery, 3D facial analysis, planning and surgical simulation system of patients with maxillofacial deformity seems to be necessary to solve the shortcoming of the traditional 2D facial analysis. Specific Aims 1. To acquire the 3-D facial value in Hong Kong Chinese Population. All the current soft tissue change indices available are based on studies of single jaw surgery in Caucasian using lateral portrait only since early 1990s (Bell et al, 1992). Nowadays, bimaxillary osteotomies are more common. And relative to Caucasian, Chinese population have obvious difference in both hard and soft tissue profile, namely, the mandibular length, cranial base, and gonial angle, etc (Ngan et al. 1997). It is noteworthy that current available cephalometric and soft tissue norm data available for Chinese / Asian are based on cephalometric and lateral portrait only. To develop a new application to produce a realistic surgical simulation and prediction, a 3D norm hard and soft tissue data seems necessary. Result from this study could also be employed for comparison to the previous golden standard from 1994 (Farkas et al., 1994). 2. To develop a 3-D soft & hard tissue assessment and planning scheme for maxillofacial deformity Based on the norm data obtained from the specific aim (1), a further insight in the variation of patients with maxillofacial deformity from normal subjects could be obtained. By measurement of the postoperative 3D data, an estimation of the 3D soft tissue – hard tissue movement ratio of Chinese population could be established.

Project Title:Clinical efficacy of two topical fluoride agents for treatment of dentinal hypersensitivity
Investigator(s):Luo Y, LO C M
Department:Dental Faculty
Source(s) of Funding:Small Project Funding
Start Date:01/2006
Abstract:
Dentinal hypersensitivity, also known as tooth sensitivity, can be described as a short sharp pain triggered by a stimulus such as cold or hot foods/beverages, sweet, sour, or acidic foods and even brushing and flossing. It may occur when the enamel is worn away or more frequently, when the gums recede and the cementum on root surface is worn away leaving the underlying dentine exposed. Both incorrect oral hygiene techniques by patients and by instrumentation of the root surface by dental professionals in the management of periodontal diseases can lead to the symptoms of dentine hypersensitivity. A variety of agents have been suggested for treatment of dentine hypersensitivity, including the use of potassium nitrate, strontium chloride, sodium fluoride, silver nitrate and calcium hydroxide. These agents generally work by blocking the dentinal tubules resulting in diminishing the movement of fluid in the tubules e.g., the hydrodynamic theory or the primary mechanism for dentine hypersensitivity. However, evidence from well-conducted clinical trials to support the claimed effectiveness of these agents is scanty. The purpose of this study is to evaluate the effectiveness of two topical fluoride agents, a 38% silver diammine fluoride solution and a 5% sodium fluoride varnish, in reducing dentinal hypersensitivity after non-surgical periodontal treatment. The objectives of the study are: 1. to describe the effectiveness of a single application of a 38% silver diammine fluoride solution in reducing dentinal hypersensitivity in teeth that are sensitive to external stimuli after non-surgical periodontal treatment; 2. to describe the effectiveness of a single application of a 5% sodium fluoride varnish in reducing dentinal hypersensitivity in teeth that are sensitive to external stimuli after non-surgical periodontal treatment; and 3. to compare the effectiveness of the above two topical fluoride agents in reducing dentinal hypersensitivity in teeth that are sensitive to external stimuli after non-surgical periodontal treatment.

Project Title:Orofacial Pain and its Functional and Psychosocial Impact

Department:Dental Faculty
Source(s) of Funding:Small Project Funding
Start Date:11/2005
Abstract:
This is a cross-disciplinary study involving the Faculties of Dentistry and Medicine that is directly related to the major research theme of Healthy Ageing. Hypotheses: o A substantial number of community-dwelling adults in Hong Kong suffer from orofacial pain (OFP) and the majority of them do not seek professional help for their condition o OFP is an under-treated condition that causes significant disability and has a serious adverse effects on people's well-being and quality of life. Purpose: To investigate a) the prevalence of OFP and its diagnostic sub-groups in community dwelling adult people in Hong Kong, b) the adverse impact of OFP on functional and psychosocial wellbeing, and c) barriers to treatment seeking for OFP symptoms. Objectives: o To determine the frequency, severity and pattern of OFP according to diagnostic sub-groups using validated patient-centred measures and clinical assessment o To describe the treatment seeking behaviour associated with OFP and factors associated with such behaviour o To assess the impact of OFP on health-related QoL using generic and condition specific health status measures o To correlate patient descriptions of OFP with clinical diagnoses Pain is closely associated with poor health. The negative effect of pain on health outcomes such as function and quality of life (QoL) among patient populations is well documented (Ahmedzai, 1995). However, little is known about the impact of pain on subjective health and well-being in community dwelling populations (Reyes-Gibby et al, 2002). Although pain is a common symptom of dental and oral disease and can have a significant impact, there is a shortage of systematic data on the prevalence, severity and consequences of orofacial pain (OFP) in general, non-clinical populations (Nikias, 1985). In a community based study in Toronto, Locker & Grushka (1987) noted that 53% of participants had experienced some pain or discomfort in the orofacial region in the previous four weeks. The majority of pain reports were tooth or gum related whereas pain in the jaws, face and oral mucosa were less common. Epidemiological studies in the USA, Canada and the United Kingdom have shown that the prevalence of oro-facial pain symptoms in adult populations ranges from 14 to 40% (Lipton et al, 1993; Locker & Grushka, 1987; Macfarlane et al 2002). Gender and age-related differences in oro-facial pain prevalence have also been noted with women and younger adults at apparently greater risk of pain symptoms, whereas older people are more likely to suffer more severe pain (Macfarlane et al, 2002; Von Korff et al, 1988). Pain may have considerable impact on people's ability to perform effectively at work, home and school. Nonetheless, not everyone seeks professional help for pain with some symptoms being ignored while others may prompt action (Macfarlane et al, 2003). It is, therefore, important to discern factors that may distinguish individuals who seek professional care from those who do not. In a population-based study of OFP in the UK, Macfarlane et al (2003) noted that less than half of their study population with OFP sought professional advice. The majority of factors associated with seeking treatment appeared to be various characteristics of pain although the time course of these factors was unclear. Locker & Grushka (1987) observed that while more than 50% of their OFP study group described pain severity as moderately severe or severe, only 40 % of those reporting pain sought advice from a doctor of dentist. Ethnic differences in the perception of and means of managing pain account, at least in part, for observed differences in treatment seeking behaviour for orofacial pain conditions (Hastie et al, 2005). Socioeconomic status is also an important factor related to treatment seeking with oral disease generally more common among those least able to access health care and leads to needless pain and suffering (Riley et al, 2005). There is presently very little information on the prevalence and impact of oro-facial pain in Southern Chinese people in Hong Kong. Most oro-facial pain prevalence studies have focused on predominantly Caucasian populations. However, a recent study in Korean elders indicated that the prevalence was higher in this ethnic group and significant disability was associated with the condition (Chung et al, 2004). In a previous population-based survey, we have shown that self-reported pain symptoms associated with temporomandibular disorders are relatively common in the Hong Kong Chinese population (Pow et al, 2001). However, the characteristics of the pain differed from other ethnic groups, no gender bias in pain symptoms was observed and treatment seeking was much lower than in Caucasian counterparts. One of the problems associated with the available epidemiological data on prevalence of OFP is that it has been collected solely by means of questionnaires with patient self-reports not being confirmed by clinical assessment (Macfarlane et al, 2004). There is, therefore, the risk that patient described pain symptoms are misinterpreted and pain symptoms due to multiple conditions may go unrecognized. Definitive diagnoses can only be obtained by clinical assessment. References: Ahmedzai S. Recent clinical trials of pain control: impact on quality of life.

Project Title:Orofacial Pain and its Functional and Psychosocial Impact
Investigator(s):McMillan AS, Wong MCM, Lam CLK, Luo Y, Zheng
Department:Dental Faculty
Source(s) of Funding:Small Project Funding
Start Date:11/2005
Abstract:
This is a cross-disciplinary study involving the Faculties of Dentistry and Medicine that is directly related to the major research theme of Healthy Ageing. Hypotheses: o A substantial number of community-dwelling adults in Hong Kong suffer from orofacial pain (OFP) and the majority of them do not seek professional help for their condition o OFP is an under-treated condition that causes significant disability and has a serious adverse effects on people's well-being and quality of life. Purpose: To investigate a) the prevalence of OFP and its diagnostic sub-groups in community dwelling adult people in Hong Kong, b) the adverse impact of OFP on functional and psychosocial wellbeing, and c) barriers to treatment seeking for OFP symptoms. Objectives: o To determine the frequency, severity and pattern of OFP according to diagnostic sub-groups using validated patient-centred measures and clinical assessment o To describe the treatment seeking behaviour associated with OFP and factors associated with such behaviour o To assess the impact of OFP on health-related QoL using generic and condition specific health status measures o To correlate patient descriptions of OFP with clinical diagnoses Pain is closely associated with poor health. The negative effect of pain on health outcomes such as function and quality of life (QoL) among patient populations is well documented (Ahmedzai, 1995). However, little is known about the impact of pain on subjective health and well-being in community dwelling populations (Reyes-Gibby et al, 2002). Although pain is a common symptom of dental and oral disease and can have a significant impact, there is a shortage of systematic data on the prevalence, severity and consequences of orofacial pain (OFP) in general, non-clinical populations (Nikias, 1985). In a community based study in Toronto, Locker & Grushka (1987) noted that 53% of participants had experienced some pain or discomfort in the orofacial region in the previous four weeks. The majority of pain reports were tooth or gum related whereas pain in the jaws, face and oral mucosa were less common. Epidemiological studies in the USA, Canada and the United Kingdom have shown that the prevalence of oro-facial pain symptoms in adult populations ranges from 14 to 40% (Lipton et al, 1993; Locker & Grushka, 1987; Macfarlane et al 2002). Gender and age-related differences in oro-facial pain prevalence have also been noted with women and younger adults at apparently greater risk of pain symptoms, whereas older people are more likely to suffer more severe pain (Macfarlane et al, 2002; Von Korff et al, 1988). Pain may have considerable impact on people's ability to perform effectively at work, home and school. Nonetheless, not everyone seeks professional help for pain with some symptoms being ignored while others may prompt action (Macfarlane et al, 2003). It is, therefore, important to discern factors that may distinguish individuals who seek professional care from those who do not. In a population-based study of OFP in the UK, Macfarlane et al (2003) noted that less than half of their study population with OFP sought professional advice. The majority of factors associated with seeking treatment appeared to be various characteristics of pain although the time course of these factors was unclear. Locker & Grushka (1987) observed that while more than 50% of their OFP study group described pain severity as moderately severe or severe, only 40 % of those reporting pain sought advice from a doctor of dentist. Ethnic differences in the perception of and means of managing pain account, at least in part, for observed differences in treatment seeking behaviour for orofacial pain conditions (Hastie et al, 2005). Socioeconomic status is also an important factor related to treatment seeking with oral disease generally more common among those least able to access health care and leads to needless pain and suffering (Riley et al, 2005). There is presently very little information on the prevalence and impact of oro-facial pain in Southern Chinese people in Hong Kong. Most oro-facial pain prevalence studies have focused on predominantly Caucasian populations. However, a recent study in Korean elders indicated that the prevalence was higher in this ethnic group and significant disability was associated with the condition (Chung et al, 2004). In a previous population-based survey, we have shown that self-reported pain symptoms associated with temporomandibular disorders are relatively common in the Hong Kong Chinese population (Pow et al, 2001). However, the characteristics of the pain differed from other ethnic groups, no gender bias in pain symptoms was observed and treatment seeking was much lower than in Caucasian counterparts. One of the problems associated with the available epidemiological data on prevalence of OFP is that it has been collected solely by means of questionnaires with patient self-reports not being confirmed by clinical assessment (Macfarlane et al, 2004). There is, therefore, the risk that patient described pain symptoms are misinterpreted and pain symptoms due to multiple conditions may go unrecognized. Definitive diagnoses can only be obtained by clinical assessment. References: Ahmedzai S. Recent clinical trials of pain control: impact on quality of life.

Abstract:
To investigate the RAPD fingerprints of C. tropicalis isolates from varying geographical locales using tDNA and rDNA directed sequence-specific and arbitrary primers in order to asses their genomic heterogeneity; to investigate their intraspecies genetic relatedness as a recent report has hinted the possible existence of a genetic variant of this yeast which may be classified as a new species.


Project Title:Ultrastructural, histochemical and molecular features of the invasive phase of Candida species
Investigator(s):Samaranayake LP, Cheung LK, Samaranayake YH, Gow N.A.R.
Department:Dental Faculty
Source(s) of Funding:Competitive Earmarked Research Grants (CERG)
Start Date:12/2002
Abstract:
The study attempts to:- 1) characterize the ultrastructural cellular features of the three hypha producing Candida species, C. albicans, C. tropicalis and C. dubliniensis, during invasion of the superficial epithelium; 2) determine qualitatively the proteolytic and lipolytic enzymes secreted at the apical tip of the invading fungal hyphae; 3) examine th etemporal regulation of the mRNA expression of seven members of the secreted aspartyl proteinases (SAP) gene family during tissue invasion by C. albicans; and 4) evaluate features mentioned above in well characterized mutants of C. albicans that have a high and low propensity to produce hyphal elements and SAP mutants that have defects in secretion of this protein degrading enzyme.


Project Title:Development and validation of a mutiarray Candida biofilm device
Investigator(s):Samaranayake LP, Samaranayake Y. H
Department:Dental Faculty
Source(s) of Funding:Small Project Funding
Start Date:12/2005
Abstract:
Candida species can exist as either commensals or opportunistic pathogens with the ability to cause a variety of superficial to systemic infections mainly in immunocompromised individuals (Samaranayake et al 2002). The major fungal species isolated from these patients is the polymorphic C. albicans (which can grow as blastospores, pseudohyphae or hyphae, and also form chlamydospores) recovered from medical devices such as central venous catheters, prosthetic heart valves, artificial voice prostheses and intrauterine devices (Hawser and Douglas, 1994, Samaranayake et al 2005). The primary event in Candida infections is their adherence to a host surface or a prosthesis leading to the formation of a biofilm which further facilitate adhesion and infection. Once established, Candida biofilms serve as a persistent reservoir of infection and in addition they offer greater resistance to antifungal agents than planktonic phase yeasts Apart from C. albicans other non-albicans species especially, C. glabrata, C. parapsilosis, C krusei and C. tropicalis are increasingly recognized as nosocomial pathogens of clinical interest (Samaranayake 2000). Several different in vitro Candida biofilm model systems have been developed to study the many features of the sessile yeast form in comparison to the planktonic form. These include biofilms grown on intravascular catheter discs, acrylic discs, cylindrical cellulose filters, those developed using perfused biofilm fermenters and the modified Robbins device (Hawser and Douglas, 1994, Ye 2004). Although these experimental systems mimic to some extent the natural in vivo physiology of Candida biofilms a simple, rapid and reproducible, mutiarray method for screening a number of different Candida strains or species and factors that affect their biofilm formation has not yet been developed. Calgary biofilm device (CBD) is a system used by bacteriologists to determine antibiotic susceptibility of multiple arrays of bacteria within a single experimental system (Ceri et al., 1999). We plan to develop the CBD for standardization of C. albicans biofilms and then demonstrate the feasibility of the system to study the relative rate of biofilm production by five other medically important Candida species. In addition we propose to use the CBD method to evaluate the growth kinetics of C. albicans biofilms and, the effect of five different dietary carbohydrates on Candida biofilm development. The biofilm ultrastructure of C. albicans, C. dubliniensis, C. glabrata, C. tropicalis, and C. krusei using the CBD over a period five days will also be studied using SEM. References 1.

Start Date:02/2005
Abstract:
Purpose: To investigate the effects of HAART on the oral health of HIV-infected individuals in Hong Kong. Key issues: Before the introduction of HAART in the management of HIV-infected individuals, opportunistic infections were common in this patient group. With the increasing use of HAART, which usually includes a protease inhibitor, the incidence of opportunistic infection has markedly decreased. Though a number of hypotheses had been proposed to explain this phenomenon, the actual mechanism is still unknown. Evidence is there that HAART exerts its effect by increasing the circulating CD4+ T cells, cellular and/or humoral responses. However, some surmise that protease inhibitors may have a direct anti-candidal effect, targeting the secreted aspartyl proteinases (Saps), an essential virulence attribute for mucosal infestation by C. albicans. The major aims of the study are; 1. To obtain data on the incidence and prevalence of oral manifestations of HIV infection by a prospective screening programme of 60 patients under HAART with regards to their oral health. Once these parameters are noted they would be correlated with immunological indices such as CD4+ T cells count and viral load. (Hypothesis: there is a decrease in the prevalence and incidence of oral manifestations of HIV-infected individual under HAART) 2. To study the oral yeast using ‘concentrated oral rinse cultures’ to determine how the use of HAART with and without protease inhibitors can affect the oral carriage rates of Candida species in HIV-infected individuals. (Hypothesis: the oral carriage rate of C. albicans in HIV-infected individuals is decreased by the use of protease inhibitors) 3. To determine C. albicans SAP1 SAP8 gene expression during oral infection and colonization in vivo and the effects of different protease inhibitors on the C. albicans SAP1 SAP8 gene expression. Results thus obtained may assist in the choice and dosage of protease inhibitors when treating these patients. (Hypothesis: SAP gene family are temporally regulated and expressed during candidal infection) 4. To determine the effects of different protease inhibitors on the adherence of C.albicans to buccal epithelial cells, which allow us to have a better understanding in the pathogenesis of oral candidal infection in HIV infection. (Hypothesis: Adherence of C. albicans to buccal epithelial cells is decreased by the presence of protease inhibitors) 5. Finally, the above data is to be collated to produce recommendations, which will improve the maintenance of oral health and hence the general health of HIV-infected individuals in Hong Kong. We are confident that the proposed studies could be successfully completed due to the expertise of the investigators. As far as we are aware, the proposed studies are pioneering investigations on HIV-infections in the South-East Asian region. Hence the data from the study should be of value not only for Hong Kong but also for the South East Asia for investigators in this field. Pending the outcome of the proposed studies, it is our intention to initiate collaborative studies with oral microbiologists and pathologists in neighbouring Asian countries.

Abstract:
The aim of this study is to investigate chronic oro-facial pain and need for treatment among older Chinese adults in Hong Kong. Objectives: 1) to study the severity of chronic oro-facial pain, the disability related to and treatment seeking behaviour for the condition among older Chinese adults and; 2) to study associations and disparities between the severity of chronic oro-facial pain, disability and treatment seeking . Chronic pain is a common and disabling condition, with a high impact on health and the health services in the community (Smith et al. 2001). According to the International Association for the Study of Pain (IASP), chronic pain is defined as pain that persists beyond normal tissue healing time, which in the absence of any other rigorous criteria, is accepted as three months (IASP, 1986). Oro-facial pain can be defined as pain related to the face and/or mouth. Many of these regional pains present a recurrent, persistent, and disabling pattern because of the complex regional anatomy of the face and mouth region, and there are often difficulties in the diagnosis and treatment of chronic oro-facial pain conditions (Chung et al. 2004). The average life expectancy has increased because of the great social and medical achievements, and the proportion of the aged in the population is increasing rapidly in most developed countries including Hong Kong. Degenerative changes in the oro-facial tissue and oro-facial pain are cumulative across the life span, which means that disability and chronic pain are generally maximized among the elderly. Older adults may be vulnerable to chronic oro-facial pain because of the aging process, their oral health status, and social circumstances. The elderly are frequently socially disadvantaged, and pain symptoms in general are more prevalent in those people least able to seek care and attention (Riley et al, 2002). In addition, a key feature of chronic oro-facial pain conditions is that individuals with the same chronic oro-facial pain may respond differently in their need for treatment and ability and desire to obtain professional advice. Thus it is very important to understand the associations and disparities between chronic oro-facial pain and treatment seeking behaviour. Chung JW, Kim JH, Kim JD et al. (2004).
