Sujak SL, Abdul-Kadir R, Omar R

Asia Pac J Public Health, 2005;17(1):15-8.
PMID: 16044826

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.

Introduction: Dental therapists are one of the main dental workforce in Malaysia and are exposed to various risk factors of MSD. However, studies on MSD among dental therapists are limited. The objectives of this study were to determine the prevalence, the sites affected, the symptom severity, the impact, the risk factors and the association between individual, biomechanical, physical and psychosocial risk factors with prevalence of MSD among dental therapists.
Materials and Methods: A survey was conducted using self-administered questionnaire which was distributed to all dental therapists in Perak, Terengganu and Kuala Lumpur in February 2017, from which a response rate of 89.2% was achieved.
Results: There was a high prevalence of MSD (87.5%) among the respondents. The MSD was found to be affecting mainly the back (69.7%), neck (66.7%), shoulders (58.7%) and wrists/hands (50.2%) while MSD of the elbow and lower extremities was found to more severe and often affect their daily work. Most of the respondents who reported MSD accommodated their own symptoms with analgesics or sought alternative treatment (20.1%). Majority reported that they often used vibratory instruments (76.1%), involved in biomechanical risk activities, and perceived that they have a high job demand and lack of authority to make decisions related to work. Age (OR: 3.58; 95% CI: 1.644, 7.773), number of extractions (OR: 4.69; 95% CI: 1.348, 16.327) as well as psychosocial factors (OR: 4.05; 95% CI: 1.547, 10.613) were significantly associated with prevalence of MSD.
Conclusion(s): Therefore, preventive measures should be implemented to reduce the burden of MSD.

Dental amalgam in fillings exposes workers to mercury. The exposure to mercury was investigated among 1871 dental health care workers. The aim of the study was to evaluate the risk of mercury exposure among dental compared to nondental health care workers and to determine other risk factors for mercury exposure. Respondents answered questionnaires to obtain demographic, personal, professional, and workplace information and were examined for their own amalgam fillings. Chronic mercury exposure was assessed through urinary mercury levels. In total, 1409 dental and 462 nondental health care workers participated in the study. Median urine mercury levels for dental and nondental health care workers were 2.75 μg/L (interquartile range [IQR] = 3.0175) and 2.66 μg/L (IQR = 3.04) respectively. For mercury exposure, there were no significant risk factor found among the workers involved within the dental care. The Mann-Whitney test showed that urine mercury levels were significantly different between respondents who eat seafood more than 5 times per week compared to those who eat it less frequently or not at all (p = 0.003). The urinary mercury levels indicated significant difference between dental workers in their practice using squeeze cloths (Mann-Whitney test, p = 0.03). Multiple logistic regression showed that only the usage of cosmetic products that might contain mercury was found to be significantly associated with the urinary mercury levels (odds ratio [OR] = 15.237; CI: 3.612-64.276). Therefore, mean urinary mercury levels of health care workers were low. Exposure to dental amalgam is not associated with high mercury exposure. However, usage of cosmetic products containing mercury and high seafood consumption may lead to the increase of exposure to mercury.

IMPLICATIONS: Exposure to the high levels of mercury from dental amalgam can lead to serious health effects among the dental health care workers. Nationwide chronic mercury exposure among dental personnel was assessed through urinary mercury levels. Findings suggest low urinary mercury levels of these health care workers. Exposure to dental amalgam is not associated with high mercury exposure. However, the usage of cosmetic products containing mercury and high seafood consumption may lead to the increase of exposure to mercury.

Fulltext Sero-prevalence of hepatitis B infection among dental professionals

Vadivale M, Tan TC, Ong CN

Singapore Med J, 1992 Aug;33(4):367-9.
PMID: 1411666

Dental employees in government institutions in a State in Peninsular Malaysia were screened for exposure to hepatitis B virus (HBV) in 1989. Almost all (96.8%) of the 217 employees responded. One quarter (24.8%) was positive for at least one serological markers to HBV; 2.4% had hepatitis B surface antigen (HBsAg) and 22.4% had anti-body to HBsAg (anti-HBs). The presence of HBsAg was unrelated to age, sex, ethnicity, geographical locality and occupations of the subjects. The prevalence of anti-HBs increased with age and was highest for ethnic Chinese (53.6%), followed by Indians (25%), compared to Malays (14.9%) (p less than 0.001) and were increased among dentists (53.1%) and assistant nurses (33.3%). The overall prevalence of HBsAg and anti-HBs were similar to the situation in the community. However, dentists and their chairside assistant nurses, with a higher proportion of Chinese, had higher anti-HBs prevalences compared with that of the general population.

BACKGROUND: The objective of this paper is to quantify the cost of periodontitis management at public sector specialist periodontal clinic settings and analyse the distribution of cost components.
METHODS: Five specialist periodontal clinics in the Ministry of Health represented the public sector in providing clinical and cost data for this study. Newly-diagnosed periodontitis patients (N = 165) were recruited and followed up for one year of specialist periodontal care. Direct and indirect costs from the societal viewpoint were included in the cost analysis. They were measured in 2012 Ringgit Malaysia (MYR) and estimated from the societal perspective using activity-based and step-down costing methods, and substantiated by clinical pathways. Cost of dental equipment, consumables and labour (average treatment time) for each procedure was measured using activity-based costing method. Meanwhile, unit cost calculations for clinic administration, utilities and maintenance used step-down approach. Patient expenditures and absence from work were recorded via diary entries. The conversion from MYR to Euro was based on the 2012 rate (1€ = MYR4).
RESULTS: A total of 2900 procedures were provided, with an average cost of MYR 2820 (€705) per patient for the study year, and MYR 376 (€94) per outpatient visit. Out of this, 90% was contributed by provider cost and 10% by patient cost; 94% for direct cost and 4% for lost productivity. Treatment of aggressive periodontitis was significantly higher than for chronic periodontitis (t-test, P = 0.003). Higher costs were expended as disease severity increased (ANOVA, P = 0.022) and for patients requiring surgeries (ANOVA, P dental treatment for periodontitis patients at public sector specialist settings were substantial and comparable with some non-communicable diseases. These findings provide basis for identifying potential cost-reducing strategies, estimating economic burden of periodontitis management and performing economic evaluation of the specialist periodontal programme.
