Cost-Effectiveness of Periodontitis Management in Public Sector Specialist Periodontal Clinics- A Societal Perspective Research in Malaysia



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.


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.


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). 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.


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.
