Abstract
Objective: This study conducted oral health program with the fluoride topical and sealant application in elementary school in Laos for 3 years in order to estimate the effect of prevention for the program on school oral health in Laos.Methods: Three primary schools were selected as an experimental group and the comparison group. 1.23% APF gel was applied 3 times every year and sealant was applied on the permanent 1st Molar for grade 1 to 5 in experimental group and caries experience was examined by use of DSRL camera photo taking and image analysis technique. The data was compared with the experimental and comparison group for 3 years.Results: Fluoride topical application and sealant in children with mixed dentition showed no difference in dft and dfs index (p>0.05). and also not so much different between two as DMFT or DMFS index in permanent dentition (p>0.05). Caries prevention effect was estimated as showed 41.4% in third grade, 15.0% in forth grade, 20.9% in fifth grade in DMFT index and the prevention effect of DMFS index was 56.1% in third grade, 38.2% in forth grade and 31.9% in fifth grade. Conclusion: It would be a more effective for prevention for the caries in case of the continuous performing the fluoride and sealant application as one of the school oral health program in Laos.
