    Backgrounds: People in Yemen and in East African countries chew khat more than five hours daily.

    Objectives: The aim of this study was to assess the relationship between khat and occlusal caries progression.

    Methods: A cohort study was carried out among 98 Yemeni khat chewers and 101 non-chewers aged 18-35 years old with early occlusal caries lesions. All participants answered questions on socio-demographic, khat , oral hygiene , sugar intake, and oral health knowledge at baseline. All posterior teeth with an early enamel lesion on occlusal surfaces detected by visual inspection at baseline were also subjected to DIAGNOdent assessment to confirm early lesion (DIAGNOdent reading 13-24). Participants were re-examined after 12 weeks. Caries progression was considered to occur when the DIAGNOdent reading was >25. Data were analyzed using Relative risk, Mann-Whitney U test, a Wilcoxon Signed-Rank test and logistic regression analysis.

    Results: Occlusal caries progression incidence between khat chewers and non-chewers, with the relative risk was 1.68. There was no significant difference in occlusal caries progression on chewing side and non-chewing side among khat chewers. Khat chewing was a statistical predictor for those with low income.

    Conclusion: Khat is a risk factor for occlusion caries progression among low income group.

    The United States faces a significant problem with access to oral health care, particularly for children. More than 50 countries have developed an alternative dental provider, a dental therapist, practicing in public, school-based programs, to address children's access to care. This delivery model has been demonstrated to improve access to care and oral health outcomes while providing quality care economically. We summarize elements of a recent major review of the global literature on the use of dental therapists, "A Review of the Global Literature on Dental Therapists: In the Context of the Movement to Add Dental Therapists to the Oral Health Workforce in the United States." We contrast the success of a school-based model of caring for children by dental therapists with that of the US model of dentists providing care for children in private practices.

    Dental quackery has been a problem for decades and is becoming a major concern in many countries, including Malaysia. Recent development of a new service offered by quacks in Malaysia is “fake braces”, which alarmed dental professionals. The fake braces appear similar to the professionally fitted orthodontic appliances comprising of archwires that are secured on brackets by coloured ligatures except they are fitted by unqualified individuals who have no formal clinical training. In addition, the orthodontic materials and dental equipment used for this illegal service were substandard and unregulated. Therefore, such fitted appliances are harmful to the teeth and oral health. Efforts to record the extent of fake braces practice and its oral health consequences have been challenging as they are marketed through the social media, and the victims were either reluctant to come forward or did not know the appropriate channel to file a complaint to the health authority. This is an expert opinion paperwith theaimsto highlight typical presentation of fake braces, modus operandi of fake braces providers, the harmful effects of fake braces on the patient’s oral health, the role of social media advertising in promoting fake braces, and the impacts to the illegal providers.

    The purpose of this study was to gather information on the oral hygiene behaviour among the visually impaired adolescents. Interview and observation methods were used to collect data. A total of 114 visually impaired adolescents were interviewed and 10 of the interviewees were selected for observation on the actual oral hygiene practices. The mean age of the sample was 16 years old. The sample comprised of 53.5% female, majority were Malays (86.8%) and most of them were from the lower income group. Fifty four percent of the sample had low vision and 45.6% were blind. All of the participants reported that they brushed their teeth daily and most of them brushed twice a day or more. Flossing (6.1%) was not common practice among this group. It was observed that they encountered some difficulties, especially when putting the toothpaste on the toothbrush and also the way that they brushed their teeth could cause detrimental effect to the oral cavity. Thus, they need to be taught on proper oral hygiene care so that they can practice safe oral hygiene care and maintain their own oral health.

    Chlorhexidine gluconate and hexitidine have been used in many oral health care products as antiplaque and antigingivitis agents. Based on the clinical observations and the plaque and gingivitis scores, chlorhexidine gluconate has been reported to be a better agent. In this study, the anti-adherence properties of chlorhexidine gluconate and hexitidine on individual bacteria strains isolated from a 3-hour plaque (Streptococcus sanguis, Streptococcus mitis 1 and Actinomyces sp.) and on a whole 6-hour plaque culture were determined and compared. The study showed that chlorhexidine gluconate inhibited almost 100 % the adherence of the individual bacteria strains and 87.7 % the adherence of a whole 6-hour plaque culture to the saliva-coated glass surface. Hexitidine appeared to be more selective in its effect. It was shown to inhibit the adherence of S. sanguis and Actinomyces sp. to saliva-coated glass surface by 86.5 % and 51.4 % respectively. Its effect on the S. mitis 1 strains is comparable to that of a whole 6-hour plaque culture where inhibition to adherence were less than 4 % for both.

    The aim of the present study is to determine the “community indicator” for dental caries among secondary school children within the Federal Territory of Kuala Lumpur (FTKL). School factors were investigated for their ability to be used as community indicators. The components encompassing school factors include: type of school, school’s examination performances at the Peperiksaan Menengah Rendah (PMR) level, in the subjects of Mathematics, Bahasa Melayu (Malay Language), Science and English, school’s socioeconomic circumstances and school’s material deprivation. The study design is ecological in nature where schools were the unit of analysis. It used aggregated data for caries experiences acquired from the Oral Health Management Information System and the school factors which were extracted from the schools’ database. The subjects involved in this study were all the (75) day type secondary schools in FTKL. However, only 55 schools had complete information both for the dental caries factor and the school factors which were available for analysis. The use of bivariate analysis suggested that the school mean DMFT was significantly associated with the schools’ performance in English (p= 0.02) and the schools’ socioeconomic code (p= 0.005). The schools’ performance in English and socioeconomic code were able to explain about 10 percent and 14 percent of the variation in the school mean DMFT respectively. The final model that included both variables together explained about 17 percent of the variation in school mean DMFT. As a conclusion, this study suggests that the schools’ performance in English at the PMR level and the schools’ socioeconomic code could be used as community indicator to identify secondary schools with higher caries level in FTKL. Nevertheless, further
    improvement of the model is needed in order to create a more reliable indicator.

    The objective of this study was to determine the effect of chewing commercially available meswak may have on levels of calcium, chloride, phosphate and thiocyanate in stimulated whole saliva. A total of 20 subjects participated in the investigation. They were distributed into two groups. Those in group A (10 individuals) were asked to first chew on a cotton roll (sized #1) followed by the chewing of an equivalent sized 5mm piece of commercially available meswak. Subjects in group B (10 individuals) did the same but, chewed on cotton roll (sized #2) followed by the chewing of an equivalent sized 10mm piece of commercially available meswak. After following a specified chewing protocol, samples of stimulated whole saliva were collected into a graduated tube at the end of every chewing regime. Calcium, chloride, phosphate and thiocyanate analysis were carried out using colour titration and spectrophotometer. Results from this investigation indicated that commercially available meswak chewing sticks apart from containing high amounts of calcium and chloride may possibly release phosphate and thiocyanate into whole saliva. These findings suggest that the commercially available meswak used as chewing sticks may have the potential of releasing substances into saliva that could influence the state of oral health. Further studies have to be carried out to ascertain the therapeutic benefits of chewing commercially available meswak.

    The main objective of this study was to assess knowledge on tooth bleaching among patients visiting dental health care centres in Klang Valley. A total of 200 patients were conveniently selected and interviewed using structured questionnaires. Among the 200 respondents, 75.5% knew about bleaching. There was no statistically significant difference in knowledge of bleaching in relation to age, gender, ethnic group and income level of the patients interviewed (p>0.05) but the education level had a significant influence (p=0.049). Respondents with tertiary education had better knowledge about tooth bleaching as compared to those respondents without tertiary education. The sources of information about bleaching came from advertisements on electronic media (65.5%), articles in newspapers and magazines (14.7%), dentists (10.9%) and family and friends (8.8%). Out of the 75.5% of respondents who knew about bleaching, 18.2% had tried bleaching their teeth using either over-the-counter products or had undergone professional bleaching treatment. The commonest reasons cited for bleaching treatment were to remove coffee and tea stains (70%) and cigarette stains (16.7%). 73.3% of these patients were satisfied with the results achieved after bleaching. However, the majority of these patients (59.6%) were unsure of the safety of these bleaching products/procedures. In conclusion, 75.5% of patients interviewed in this study knew that bleaching is one of the treatment options available to improve dental aesthetics but only 18.2% have tried bleaching their teeth. Their main source of knowledge about bleaching came from advertisements on electronic media.

    The main aim of this study is to get the Malaysian chief dentists’ perceptions of the oral health promotion activities currently taking place in their respective states in terms of the strengths and weaknesses of these activities. A qualitative method using an open-ended questionnaire was used to obtain this information. The study samples consist of all the chief dentists in Malaysia who represented a majority of population in their states. The results showed that the main current oral health promotion activities is dental health education talks which aims to disseminate oral health information through health education talks, toothbrushing drills, dental exhibition, pamphlets, brochures and publications. Half of the respondents felt that the commitment of the staff, the support of the public sectors and collaboration with other agencies are the main strengths while the lack of staff and fund has been said as the weaknesses. A range of opportunities however exist to strengthen oral health promotion in Malaysia.

    Tobacco use is linked with many serious illnesses, such as cancer, cardiopulmonary diseases, as well as with many health problems. Every year, the use of tobacco products causes a heavy toll of deaths and severe human disease worldwide. One of the many health problems linked to tobacco use is its detrimental impact on oral health. Tobacco causes a whole series of oral health problems, ranging from life-threatening (precancerous changes leading to oral cancer) and serious (periodontal disease, teeth decay) to social (bad breath). Tobacco is consumed through the mouth in a variety of forms, varied from smoked tobacco to smokeless tobacco chewing on itself or combined with areca nut. All these forms of tobacco have damaging effects on the oral health. The most significant preventive measure to prevent the oral health problems caused by tobacco use is to stop using tobacco products. The risk of developing oral cancer drops rapidly when a smoker ceases tobacco use. After ten years of not using tobacco, an ex-smoker/user's risk of oral cancers is about the same as that for someone who has never smoked. To stop using tobacco products is not an easy task. Fortunately, there are a number of therapies available to assist in quitting of tobacco. It is important to remember that, while it will be difficult, ceasing to use tobacco has immediate health benefits, including increased life expectancy and reduced risk of tobacco related diseases and conditions.

    A cross-sectional study was conducted to ascertain the relationship between parental oral health perception on the importance of the deciduous dentition and the dental caries status of their preschool children. Clinical oral examination of the preschool children was performed and self-administered questionnaires were given to the parents to be completed. Four hundred and eight preschool children were examined and 390 of their parents responded to the self-administered questionnaire. Those parents who brought their children for regular dental check-up at least once a year; favoured restorative treatment and practised tooth brushing habit before bedtime were more likely to have children with significantly lower mean 'dft' as well as higher proportions of caries free mouth (> 50 %). Those children who started early in practising tooth brushing also had better dental caries status but the differences were not significant. However, there were no significant and appreciable differences in their mean 'dft' with respect to the frequencies of tooth brushing per day. It was concluded that parents with better oral health perception as reflected by those parents who (a) practiced regular dental check-up for their children; (b) favoured restorative treatment for their children's decayed deciduous teeth; (c) ensured their children brushed their teeth before bedtime are associated with better dental caries status of their preschool children.

    Dental fear is a hindrance to the effective provision of oral health care and causes patients to delay, or even avoid necessary care altogether. The aim of this study was to determine the prevalence and level of dental fear, to identify specific fear provoking stimuli and also to explore the avoidance behaviour among the respondents. A cross-sectional study was conducted on a sample of 407 antenatal mothers utilizing the Kleinknecht's Dental Fear Survey Questionnaire. The overall prevalence of dental fear was 94.1% of which 67.6% of the subjects reported low fear levels, 26.5% were moderately fearful while none were highly fearful. Only 5.9% of the subjects reported no fear. The drill and anaesthetic needle were identified as the most fear provoking objects. Subjects with moderate fear were about 6.4 times (OR=6.39; 95%CI 3.81-10.75) more likely to avoid making appointments and 6 times (OR=6.05; 95% CI 3.20-11.50) more likely to cancel appointments compared to subjects with lower levels of fear. This. study indicates that dental fear is a common problem among antenatal mothers contributing to poor dental attendance.

    The objective of the study was to attempt to verify the cause of self-reported oro-facial pain among 12-yearold children, objectively via a clinical examination. This is a descriptive, cross-sectional survey using a combination of self-reported questionnaire, face-to-face interview and clinical oral examination. The children were first asked to answer a self-filled questionnaire about their oro-facial pain experience in the past 4- weeks. In order to verify its cause, a clinical examination and an interview followed. Normative oral health status data was also collected. The sample was 1492 Malay schoolchildren with diverse socioeconomic background from the states of Johore, Kelantan and Sabah. The sample size for each state was calculated to give a sampling error of not more than 5 %. In each state, quota sampling was done to achieve a balanced distribution between gender and location. The data collected were normative status for caries, periodontal disease and traumatized teeth. Orofacial pain experience represented the subjective status for oral well-being. The cause of pain was confirmed through a clinical examination. The normative oral health status data implies a very low untreated disease and good oral health among the schoolchildren. However the subjective health status, as reflected by the prevalence of pain suggested that oro-facial pain and suffering was high (27.3%) with about 49% "of moderate and severe" intensity. The two main causes were caries and mouth ulcers. However in about onequarter of pain cases, diagnosis cannot be confirmed in the field survey setting. More than one-half of those with pain experienced disturbed sleep and study. It was concluded that overall oral health status and well-being can be better described if normative data is complemented with subjective data such as pain prevalence. The study shows that the majority (more than 75 %) of cases of subjective pain can be objectively verified in a field epidemiology survey setting. The reliability of the subjective data can be improved by a clinical examination as compared to unverified self-report. The study also confirms that the major source of oro-facial pain among the 12 year-olds were caries and mouth ulcers.

    This is a preliminary survey on cast partial denture designs in the commercial dental laboratories. This survey was carried out for a month in three commercial dental laboratories in Klang Valley and Shah Alam which produce metal dentures in cobalt-chromium. One hundred and ten questionnaires with the designs were collected and analysed. The framework design on the cast was transferred into the design sheet section of the questionnaire. The aim was to investigate communication regarding denture design between clinicians and dental technician and the dentists' dependency on the technician. The design of cobalt-chromium partial dentures in relation to oral health was also assessed. The results indicated that 43.6% of the dentist who used the three laboratories delegated their removable partial design work to the dental technician. More than half of the dentists had some communication with the technicians, and only 18.2 % of the dentists prescribed clear instructions with details of components regarding denture design. Continuing dental education on partial denture design for both clinicians and dental technicians would be of value to provide reinforcement in the knowledge of the basic concept on denture designing. Communication and understanding between both parties would probably improve the quality of cobalt-chromium dentures constructed.

    Long term evaluations of impacts of community
    based health promotion programmes are not an easy or
    straightforward task to do due to lack of validated and
    reliable indices. Objective: To develop and test an index
    to measure schoolchildren’s oral health knowledge,
    attitudes, and behaviour as a result of a school-based health
    promotion programme in Malaysia called the Doktor
    Muda (Junior Doctor) Programme (DMP). Materials and
    Methods: The index was developed in English based on
    the DMP module and translated into Malay. The Malay
    version was tested on 174, 11-12 year old schoolchildren.
    Psychometric analysis of the index involved content and
    face validity tests as well as factor analysis, internal and
    test-retest reliability. Results: Factor analysis yielded 3
    factors with groups of items viz. oral health knowledge
    (OHK), oral health attitudes (OHA) and oral health
    behaviour (OHB). The Cronbach’s alpha coefficients of the
    three factors were 0.61, 0.73, and 0.64, respectively. The
    Kappa coefficients were 0.70, 0.77 and 0.73, respectively
    (intraclass correlation coefficients = 0.72, 0.70 and 0.78).
    The final questionnaire comprised 33 items, namely; OHK
    11 items, OHA 15 items, and OHB 7 items. Conclusion:
    The Health Promotion Questionnaire Index (HPQI) to
    measure the DMP impact on schoolchildren’s oral health
    knowledge, attitudes, and behaviours was empirically
    verified to be valid and reliable for use among 11-12 year
    old Malaysian schoolchildren.

    Background: In Malaysia, preschool teachers have long been utilised as oral health educators. However their level of oral health knowledge and effectiveness of the training they received are seldom investigated. This study aims to evaluate the of oral health education seminar (OHE) held for public preschool teachers (KEMAS) in terms of the improvement of their knowledge, practices and attitudes.
    Methods: This was a one arm interventional study (before and after survey following OHE seminar intervention). All KEMAS preschool teachers (n=107) in Hulu Terengganu were invited to attend OHE seminar which consisted of 1 hour lecture and 40 minutes OHE demonstration. Pretest questionnaire was collected before the seminar started and post-test questionnaire was collected two weeks later. A self-administered questionnaire used in this study was adapted from “preschool teachers’ knowledge, practices and attitudes towards oral health”, National Oral Health Survey of Preschool Children, 2005. Data were analysed using descriptive and McNemar test, SPSS version 15.0.
    Results: Of 107 subjects, only 61 teachers responded yielding to 57% response rate. All subjects were female with mean age of 46 years (SD: 6.03). Overall, there was an improvement of teachers’ oral health knowledge, practices and attitudes after the seminar. Several items seem to have be improved significantly after the seminar, for example knowledge item on factors causing periodontal disease (p=0.03). In terms of practice, all teachers reported they brushed teeth at least twice daily using fluoridated toothpaste and use of dental floss was increased significantly after the seminar (p<0.001). Majority of teachers have positive perceptions on their roles in oral health education.
    Conclusion: Oral health education seminar appeared to be effective at influencing certain aspects of teachers’ oral health knowledge, practices and attitudes.

    This paper attempts to review epidemiological studies of oral cancer and precancer in Malaysia. The defmitions of prevalence, incidence, risk habits and oral cancer and precancers were discussed to better understand' the different types of studies conducted, which would be important in making comparisons between studies. Currently, epidemiological data on oral cancer in Malaysia are sketchy. The only incidence data for oral cancer in Malaysia was reported by Hirayama in 1966, 35 years ago. He estimated that 3.1 new cases per 100,000 population were diagnosed for the year 1963. A number of histopathological data of oral and maxillofacial biopsies were reported. Oral cancer accounted for one-fifth of all oral biopsies. A national study on oral mucosal lesions in Malaysia carried out in 1993/4 reported that there was a variation seen in the occurrence of oral premalignancy among the ethnic groups. The Indians and the indigenous people of Sabah and Sarawak were identified as high risk groups for oral cancer and precancer. It was also observed that both of the ethnic groups chewed betel quid. In conclusion, the epidemiological studies have provided useful data, which may be used in planning for future oral health programmes and research towards enhancing Malaysia's on-going effort in preventing the occurrence of these diseases.

    The present study analysed the records of 342 elderly subjects aged 55 years and above of different ethnic groups to ascertain the types and level of their unperceived dental needs. The overall percentage of unperceived needs was highest among the Malays (96.1% or 74/77 subjects) and among the men (88.5% or 139/157 subjects). The unperceived need for prosthetic treatment was highest among the Malays and Chinese as well as among women, whereas the unperceived need for treatment for periodontal disease was highest among the Indians. The data for unperceived needs for prosthetic treatment as well as for treatment for caries and periodontal disease were somewhat similar among men. Within each ethnic group, variations among sex in the unperceived needs for the various dental symptoms were also noticeable. Further research is indicated to ascertain the role of traditional and cultural concepts and dogmas in determining the importance attached to the various dental health symptoms within each ethnic group.
