To assess the oral health behaviors of children with Autism Spectrum Disorder (ASD) and explore attitudes and barriers in providing oral care by their parents. A cross-sectional, mixed method study design, which comprised of quantitative and qualitative sections was conducted. The quantitative part assessed the oral health behavior through a parent-proxy report questionnaire whilst the qualitative part assessed parents’ overall perspective on maintenance of oral health in children with ASD through an in-depth interview using semi-structured questions. All children below the age of 16 who have been clinically diagnosed with ASD and registered at the Pediatric Dental Clinic were included. The sample consisted of twenty children with ASD. Most of the sample were male and between 5-8 years old. Majority had good oral health behaviors but some exhibited self-injurious behaviors that may affect oral health. Severe characteristics of ASD, co-morbid conditions and incompetent health professionals were reported as barriers in oral care by parents of these children. Despite having good oral health behaviors, several barriers and challenges were expressed by these parents with ASD when providing home oral care or bringing them for dental appointment. Continuous support for parents with ASD child by dental professionals is essential to help overcome the real challenges and barriers in providing oral care among these parents.

Tobacco usage among dental students and the amount of training they received may have an impact on tobacco cessation activities undertaken for their patients. This study aims to assess Malaysian dental students’ tobacco use, exposure to second-hand smoke and their attitude towards tobacco control activities and curriculum. This was a cross-sectional study using a self-administered questionnaire adapted from the Global Health Professions Students Survey (GHPSS). The questionnaire was distributed to all Malaysian fourth and fifth year dental students in four public dental schools (n=372), namely University of Malaya (UM), Universiti Teknologi Mara (UiTM), Universiti Kebangsaan Malaysia (UKM) and Universiti Sains Islam Malaysia (USIM). The data were analysed using descriptive and chi square tests. In total, (n=349) respondents completed the questionnaire, yielding a 93.8% response rate. Although the prevalence of Malaysian dental students who ‘ever smoked’ was 21.2%, the prevalence of current smokers was low (2.3%). About 62% and 39% of students reported having been exposed to second-hand smoke in public and at home, respectively. USIM students were significantly less likely to recall having received training about approaches to smoking cessation (52.9%, p<0.001). Significantly fewer smokers than non-smokers agreed on tobacco banning policy. Regardless of their smoking status, the majority of dental students showed positive attitudes towards dentists’ role in tobacco cessation. Tobacco user among Malaysian dental students was low. There were statistically significant differences between ever smokers and non-smokers’ attitudes towards tobacco banning policy. The majority of dental students showed positive attitudes towards dentists’ role in tobacco cessation.

Introduction: The objective of this study was to assess parental acceptance and factors that influenced their perceptions towards the use of dental therapists in providing treatment to children in private dental practice settings. Methods: A cross-sectional study was conducted on randomly selected parents of 11-year-old schoolchildren in Selangor using a self-administered structured questionnaire. The survey consisted of three sections: socio-demographic characteristics, dental service utilisation and parental acceptance towards dental therapists in providing seven types of preventive and operative dental procedures. Results: The response rate was 83.1%. Overall, most parents regarded dental therapists providing dental care to their children in private dental care settings as acceptable, particularly on preventive treatment, namely ‘seeking advice on oral hygiene care' (87.8%) and ‘applying topical fluoride' (83.2%). In the multivariate analysis, younger parents and those who had preferences over private sectors were most likely to accept at least four dental procedures to be rendered to their children by dental therapists. Overall, respondents who were younger (OR = 1.40, 95% CI = 1.62, 1.92), lived in urban locality (OR = 1.77, 95% CI = 1.28, 2.45) and had a recent dental visit (OR = 1.51; 95% CI = 1.10, 2.07) were more likely to have an overall positive perceptions towards dental therapists. Conclusion: Most parents regarded dental therapists providing care to their children in private dental settings as acceptable and this was associated with their age, place of residence and past dental experiences.

Introduction: Despite the increased number of homeless people in Malaysia, there is limited information on their oral health status and oral health-related quality of life (OHRQoL). This study aims to investigate the impact of caries experience, dental anxiety, oral health (OH) knowledge, and OH behaviours on the OHRQoL of homeless adults in Malaysia, as well as to determine the mediation role of caries experience towards OHRQoL. Methods: A cross-sectional study involving homeless persons was conducted in five states in Malaysia. Dental caries was examined using Decayed, Missing and Filled Teeth (DMFT) index. Face-to-face interview was conducted to collect information about OH knowledge and behaviours, dental anxiety, and OHRQoL using validated questionnaires. Meanwhile, descriptive and bivariate analyses were conducted using SPSS. Partial least squares structural equation modelling (PLS-SEM) was performed to test the hypotheses of the conceptual model with the support of SmartPLS. Results: A total of 192 homeless people completed the questionnaire and oral examination. The majority were male (84.9%), with a mean age of 43.72 (SD = 11.6). The severity of OHRQoL impact (mean OHIP score) was 18.61(SD = 11.3). There were significant independent relationships between dental anxiety (β = 0.306, p < 0.001) and caries experience (β = 0.280, p < 0.001) on the homeless OHRQoL. It was found that the relationship between OH knowledge and OHRQoL was significantly mediated by caries experience. Conclusion: According to the structural model, caries experience, dental anxiety, and OH knowledge have significantly impacted the OHRQoL of the Malaysian homeless. These studied factors should be considered in the adoption of a holistic approach to improve the OHRQoL among homeless people in Malaysia.
