Abstract:
ObjectiveTo study an application of a method of improving the quality of sampling in review to determine the light areas of endemic fluorosis(referred to as endemic fluorosis) in quality control. Methods Of 15 light endemic fluorosis township(town), six were randomly sampled, and the prevalence of dental fluorosis in 22 village primary school children aged 8 to 12 were reviewed to determine the improved quality of sampling in Xuyong county Sichuan province. ResultsSix townships(towns) were selected by simple random sampling from 15 endemic fluorosis townships(towns) for review inspection in Xuyong country. A total of 22 villages were verified, accounting for 22.7％ of the total 97 villages verified. Of the 416 children for review inspection of dental fluorosis, 383 children were positive. The consistent rate of children' s dental fluorosis was 92.07％, and the verification to be slight villages was up to 21 endemic villages, accounting for 95.45％. ConclusionsThe application of a method of improving the quality of sampling can improve the efficiency of quality control, and improve the accuracy. It is a novel quality control method.
