Caries experience of 5–6-year-old and 12–13-year-old schoolchildren in central and western Nepal

Objective: To describe and analyse the caries experience and caries prevalence in the deciduous dentition of 5–6-year-old schoolchildren and in the permanent dentition of 12–13-year-old schoolchildren in western and central Nepal. Design: Non-randomised cross-sectional surveys conducted by trained and calibrated examiners. Setting: Surveys were conducted in private and government rural and urban schools at 10 sites along the Terai and the foothills in eight districts of western and central Nepal. Subjects: A total of 2,177, 5–6-year-old and 3,323, 12–13-year-old schoolchildren from urban and rural areas were examined under WHO Pathfinder methodology. Outcome measures: Prevalence of caries and dental caries experience (dmft/DMFT). Results: The caries prevalence and mean dmft score of 5–6-year-olds was 67% and 3.3 (urban 64% and 2.9; rural 78% and 4.0). The caries prevalence and mean DMFT score of 12–13-year-olds was 41% and 1.1 (urban 35% and 0.9; rural 54% and 1.5). The d/D-component constituted almost the entire dmft/DMFT index. Conclusion: The recorded prevalence of untreated dental caries in schoolchildren requires an appropriate oral health response based primarily on prevention and health promotion. Foremost in this regime would be the promotion and use of accessible and affordable fluoridated toothpaste.
