RESUMO
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 < 0.001). Providers generally spent most on consumables while patients spent most on transportation. CONCLUSIONS: Cost of providing 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.

The aim of the present study was to determine the oral health status of 16-year-old Malaysian school children. The prevalence of caries was 75.5%. More than 60% of subjects had caries experience by teeth (DMFT) scores of 0-3. The largest component of the DMFT and caries experience by surface index was the filled component. Females had higher caries prevalence and caries scores than males. The mouth and tooth prevalences of enamel defects were 56% and 21.8%, respectively. The most common type of enamel defects observed were diffuse opacities, affecting 95.5% of affected subjects and 92.1% of affected teeth. One-third of subjects had healthy gingival conditions, 8.6% had bleeding gingivae, 55.1% had calculus and 3% had pockets. Less than 1% of subjects wore or required dentures. Cleft lip and/or palate was uncommon. This study shows that the prevalence of caries and DMFT scores have declined over the last 30 years.

OBJECTIVES: The aim of this study was to evaluate the cost-effectiveness of the national public sector specialist periodontal program in the management of periodontal disease. METHODS: This was a multicenter, time motion, prospective, economic evaluation study involving a total of 165 patients with periodontitis recruited from five selected specialist periodontal clinics. Treatment costs were measured in 2012 Malaysian ringgit (MYR) and estimated from the societal perspective using step-down and activity-based costing methods, and substantiated by clinical pathways. A cost-effectiveness analysis was done to compare the specialist periodontal program with a hypothetical scenario in which patients attend biannual dental visits only for regular dental check-up and scaling. The incremental cost-effectiveness ratio was defined as the difference in cost per gain in quality-adjusted life-years (QALYs) and clinical attachment levels (CALs). One-way scenario-based sensitivity analyses were carried out to assess the uncertainty of inputs. RESULTS: The average cost for managing patients with periodontitis was MYR 376 per outpatient visit and MYR 2820 per annum. Clinically, a gain of an average of 0.3 mm of CAL was attained at post-treatment (paired t test, P < .001). Patients gained an average of 3.8 QALY post-treatment (paired t test, P < .001). For cost-effectiveness analysis, the specialist periodontal program was more cost-effective than the hypothesized biannual dental visits, with incremental cost-effectiveness ratios of MYR 451 and MYR 5713 per additional QALY and millimeter CAL gained, respectively. CONCLUSIONS: It is very cost-effective for the public sector to provide specialist periodontal treatment for patients with periodontitis according to the World Health Organization criteria and when compared with conventional biannual dental treatment.
