This study investigated the sociodemographic profiles of patients attending public and private dental clinics and the types of treatment received. Patients (n=454) were interviewed using a structured questionnaire at two public and four private clinics in Sibu District, Sarawak. Generally, Chinese (74.7%), females (60.0%) and urban dwellers (83.7%) were more likely to visit the dentist. Both clinics had more females and more Chinese but private clinics had a lower percentage of female attendees (53.1% versus 67.0%) but a higher percentage of Chinese (85.0% versus 64.5%). Private attendees were younger (mean age of 31.0 years compared to 41.0 years) and from higher income households (median value of MR 2,000 versus MR 900) than public attendees. Treatments were mostly curative and a third of the visits were associated with painful conditions. Age (p=0.006), gender (p=0.003), ethnicity (p<0.001) and household income (p<0.001) were associated with the type of clinic visited. Choice of clinic was not related to having painful conditions (p=0.970). To ensure a more affordable and equitable distribution of oral healthcare, health planners need to identify disparities in the utilization of services and differences between public and private attendees.
A questionnaire was mailed to 1217 dentists whose names appear in the Dentist Register of 1987 in order to assess their awareness and acceptance of hepatitis B vaccine and their pattern of glove usage. Almost all the respondents (99.6%) were aware of the availability of the hepatitis B vaccine yet only 44.8% have received the vaccine. This is in spite of the fact that the majority (61.2%) of the vaccine non-acceptors have no reservations concerning the vaccine. About 71% and 63% of the vaccine-acceptors and non-acceptors respectively believed that the risk of their contracting hepatitis B was high or very high. About 22% of the vaccine non-acceptors never used gloves when treating patients as compared to 9% among vaccine acceptors. Overall, about 78% of the respondents have experienced needleprick injuries in the 3 years preceding the survey.
To assess the cross-sectional construct validity of the Malay-translated and cross-culturally adapted FACT-H&N (v 4.0) for discriminative use in a sample of Malaysian oral cancer patients. A cross-sectional study of adults newly diagnosed with oral cancer. HRQOL data were collected using the FACT-H&N (v 4.0), a global question and a supplementary set of eight questions ('MAQ') obtained earlier in pilot work. Of the 76 participants (61.8% female; 23.7% younger than 50), most (96.1%) had oral squamous cell carcinoma; two-thirds were in Stages III or IV. At baseline, patients' mean FACT summary (FACT-G, FACT-H&N, FACT-H&N TOI, and FHNSI) and subscale (pwb, swb, ewb, fwb, and hnsc) scores were towards the higher end of the range. Equal proportions (36.8%) rated their overall HRQOL as 'good' or 'average'; fewer than one-quarter rated it as 'poor', and only two as 'very good'. All six FACT summary and most subscales had moderate-to-good internal consistency. For all summary scales, those with 'very poor/poor' self-rated HRQOL differed significantly from the 'good/very good' group. All FACT summary scales correlated strongly (r>0.75). Summary scales showed convergent validity (r>0.90) but little discriminant validity. The discriminant validity of the FHNSI improved with the addition of the MAQ. The FACT-H&N summary scales and most subscales demonstrated acceptable cross-sectional construct validity, reliability and discriminative ability, and thus appear appropriate for further use among Malaysian oral cancer patients.
The Oral Health Division, Ministry of Health in Malaysia piloted clinical pathways (cpath) in primary care in early 2003. This study investigated the knowledge, perception of cpaths and barriers faced by the clinicians involved in the pilot project. Self-administered questionnaires were sent to the clinicians (n=191). Dentists (67.9%) and dental nurses (70.6%) had good overall knowledge of cpaths. The majority of the clinicians (67.9% to 95.6%) perceived cpath positively in all areas. Only 9.2% of dentists encountered difficulties in using cpath forms compared to 28.4% of dental nurses. A higher proportion of dental nurses (73.5%) compared to dentists (64.8%) were willing to continue using cpath. The majority of dentists (76.7%) and dental nurses (73.1%) were willing to participate in future development of cpaths. Overall, there was evidence of managerial support for the pilot project. A follow-up of the pilot project was somewhat lacking as less than half (43.3%) of the clinicians reported that the state coordinator obtained feedback from them. The findings auger well for the future implementation of cpath should the Oral Health Division decide to adopt cpath routinely in the public oral health care service.
Recent studies suggested that exposure to household smoking (HHS) could be a modifiable risk factor for caries development among children. Majority of the studies were cross sectional in nature. Therefore, a case-control study was designed to test the hypothesis that HHS is a risk factor to caries experience in permanent teeth. Calculation of sample size was based on the ratio of 1 case to 4 controls. Case was defined as a child aged 13-14 years old with caries in at least one second permanent molar and control was defined as a child from the same age and school with no caries second permanent molars. Matching was done for gender and ethnicity. School dental records provided information on oral health status and oral hygiene status. Information on HHS, socio-economic status, child’s smoking status and child’s oral health practices were obtained from a self- administered questionnaire, completed by the children and their parents. The result showed that 55.9% of the case group was exposed to HHS, as compared to 44.1% among the control group. In the final multiple logistic regression model after controlling for important risk factors for caries, children with caries were almost twice as likely to have been exposed to HHS for more than 10 years as compared to children with no caries, (Adjusted OR=1.90 and 95% CI=1.35, 2.60). In addition, children who only received dental care from the school dental service had reduced risk of having dental caries by more than one third (36%) as compared with those who received dental care from school dental service (SDS) as well as had additional dental problem solving visit outside SDS (Adjusted OR=0.64 and 95% CI=0.50, 0.90). It is concluded that exposure to HHS for a long duration (> than 10 years) increase the risk to have caries experience in permanent teeth of children.

A house to house random survey on elderly subjects was undertaken in the District of Klang in Malaysia. The objective of this study was to investigate the prevalence of oral mucosal lesions (OML) among the elderly in this area. The primary units in the sampling frame were the Enumeration Blocks (EBs) as defined under the population census. All households of the selected EBs were considered as sampling units and members aged 60 and above were considered as respondents. There was a slight preponderance of females, with the Malays comprising the majority of the subjects. Of the 486 respondents, mean aged 69.1 +/- 7.3 yr, 111 had at least one oral mucosal lesion, a prevalence of 22.8%. A total of 145 lesions were detected. The prevalence of OML was highest among Indians and least among the Chinese. The most common finding was tongue lesions, recording a prevalence of 10.7%, followed by oral pigmentation (4.9%) and white lesions (4.3%). Denture related lesions were comparatively low at 2.5%. Two cases of oral cancer if representative would give a relatively high prevalence of 0.4%.
The objective of this study is to share cost analysis methodology and to obtain cost estimates for posterior restorations in public sector dental clinics. Two urban and 2 rural dental clinics in Selangor state were selected. Only cases of 1 posterior restoration per visit by dental officers were included over 6 months. One capsulated amalgam type, 1 capsulated tooth-colored, and 1 non-capsulated tooth-colored material were selected. A clinical pathway form was formulated to collect data per patient. Annual capital and recurrent expenditures were collected per clinic. The mean cost of an amalgam restoration was RM 30.96 (sdRM 7.86); and tooth-colored restorations ranged from RM 33.00 (sdRM 8.43) to RM 41.10 (sdRM 10.61). Wherein 1 USD = RM 2.8. Restoration costs were 35% to 55% higher in clinics in rural areas than in urban areas. The findings demonstrate economy of scale for clinic operation and restoration costs with higher patient load. Costs per restoration were higher in rural than in urban dental clinics. More studies are recommended to address the dearth of dental costs data in Malaysia.
BACKGROUND: The rising burden of cancer in the developing world calls for a re-evaluation of the treatment strategies employed to improve patient management, early detection and understanding of the disease. There is thus an increasing demand for interdisciplinary research that integrates two or more disciplines of what may seemed to be highly unrelated and yet very much needed as strategies for success in research. This paper presents the processes and barriers faced in building partnerships in oral cancer research in a developing country.
METHODS: A case study was undertaken in a developing country (Malaysia) to assess the strengths and weaknesses of the situation leading to the formation of a multidisciplinary research partnership in oral cancer. Following the formalization of the partnership, further evaluation was undertaken to identify measures that can assist in sustaining the partnership.
RESULTS: The group identifies its strength as the existence of academia, research-intensive NGOs and good networking of clinicians via the existence of the government's network of healthcare provider system who are the policy makers. The major weaknesses identified are the competing interest between academia and NGOs to justify their existence due to the lack of funding sources and well trained human resources.
CONCLUSIONS: With the growing partnership, the collaborative group recognizes the need to develop standard operating procedures (SOPs) and guidelines for the sharing and usage of resources in order to safeguard the interest of the original partners while also attending to the needs of the new partners.
Identification of diagnostic markers for early detection and development of novel and therapeutic agents for effective patient management are the main motivation for cancer research. Biological specimens from large cohort and case-control studies which are crucial in providing successful research outcomes are often the limiting factor that hinders research efforts, especially in developing countries. Therefore, the Malaysian Oral Cancer Database and Tissue Bank System (MOCDTBS) were established to systematically collect large number of samples with comprehensive sociodemographic, clinicopathological, management strategies, quality of life and associated patient follow-up data to facilitate oral cancer research in Malaysia. The MOCDTBS also promotes sharing among researchers and the development of a multidisciplinary research team. The following article aims to describe the process of setting-up and managing the MOCDTBS.
