Abstract

Objectives: It is essential to measure and monitor the burden of dental caries and periodontal disease (PD) in Korea's ageing population due to their potential impact on morbidity, quality of life and economic condition. This study aimed to quantify the size of burden of dental caries and PD using the disability-adjusted life years (DALYs), and their trends. Methods: DALYs were estimated using incidence-based approaches to calculate the burden of dental caries and PD from 2013 to 2015 in Korea. Incidence and prevalence were estimated using medical claim data by specific algorithms. Additionally, sensitivity analysis was conducted to investigate possible weakness in the study methodology. To conduct the sensitivity analysis, we modified the algorithms to estimate prevalence and incidence. Results: The burden of dental caries and PD increased by 39.2% and 57.0%, respectively, between 2013 and 2015. In 2015, dental caries and PD ranked 11th and 25th, respectively, in terms of the leading causes of DALYs. The burden of dental caries was the most substantial in children aged 0-9 years, while that of PD was the most substantial among those in their ages of 40 and 50 (per 100 000 population). After sensitivity analysis with a modified disease algorithm, the magnitude of disease burden changed considerably. Conclusions: Dental caries and PD constitute substantial burdens in South Korea. Despite the known limitations, medical claims data can be a powerful resource for conducting timely and cost-effective measurements of oral health. In countries, where universal dental schemes are available, there is need to estimate the burden of oral disease using claims data, for methodical advances in the research field.
