The objective of this study was to assess the perceptions of Malaysian HIV-positive subjects towards the attitude of dental personnel in providing oral care to them. The study design was cross-sectional with the sampling frame comprising of 27 Government Drug Rehabilitation Centres throughout Malaysia. A convenience sample was then taken from 20 centres with the highest enrolment of HIV-positive subjects. A self-administered questionnaire was used to elicit information on the perception of HIV-positive subjects towards the attitude of dental personnel in providing oral care to the patient with HIV-positive. The study sample consisted of 509 HIV-positive individuals with a mean age of 31.3+/-12.9 years old. Of these, only 15.1% attended a dental clinic after confirmation of HIV-positive status. The study demonstrated that 67.5% of the HIV-positive subjects disclosed their status voluntarily to the dentists and majority of the dentists (76.9%) did not show any negative reaction on knowing their HIV positive status. There was also no difference in the attitude of auxiliary staff toward the above disclosure. In conclusion, the study showed that oral health care personnel are more receptive to the HIV-positive subjects receiving dental care and treatment.
The aim of this study was to investigate the prevalence and psychosocial impact of enamel defects among 16-year-old school children on the island of Penang. The data were collected through a self-administered questionnaire survey and an oral examination, using the Modified Developmental Defects of Enamel Index (FDI, 1992). In all, 1024 subjects were selected using a multistage random sampling technique. About two-thirds of the sample (67.1%) had at least one tooth affected by enamel defects. Enamel opacities accounted for 85.6% of the total condition. Diffuse-type opacity predominated (63.5%). Among subjects who expressed dissatisfaction, 18.8% reported covering their mouths when smiling, 8.7% avoided going out with friends and 39.1% had consulted their dentists. About 17% of the subjects reported that their parents had complained about the color of their front teeth but only 5.7% had experienced being teased by their friends about the problem. Two-thirds of the subjects were affected by enamel defects involving at least one tooth; however, the esthetic perception and psychosocial impact of those affected were minor.
The prevalence of concurrent use of combustible and electronic cigarettes (dual-use) is on the rise among Malaysian adolescents. This study compares nicotine dependence among exclusive cigarette users, e-cigarette users, and dual adolescent users. A total of 227 adolescent smokers completed a self-administrated questionnaire with items based on Hooked on Nicotine Checklist (HONC) incorporated. Endorsement of at least one HONC item indicates nicotine dependence. Exhaled carbon monoxide readings and salivary cotinine data were also collected. Over half (52.9%) of the participants were exclusive e-cigarette users (EC). The prevalence of exclusive conventional cigarette smokers (CC) and dual users was 11.9% and 35.2%, respectively. Adolescents who have mothers with secondary school education were more likely to become addicted to nicotine (Adjusted Odd Ratio (aOR) = 2.72; 95% CI = 1.17-6.32). Adolescents' "mother's education" level predicted nicotine dependence. This highlighted the need to target families within the identified demography with a more supportive anti-tobacco program.
