Abstract: Objective This study aimed to investigate the prevalence of dental fluorosis and related oral diseases in Tianjin and analyse the influence of dental fluorosis on the oral health status of 12-14-year-old adolescents in Tianjin.Methods Stratified cluster random sampling was used for sampling. Data collection was combined with oral health examination and questionnaire survey.Results The prevalence rate of dental fluorosis was 43.7%, and the community index of dental fluorosis (CFI) was 0.97. The prevalence of dental fluorosis was mild. The prevalence rate of dental fluorosis in the urban area was 63.9%, and the CFI was 1.47. The level of dental fluorosis in the urban area was moderate, and a significant difference was noted between the urban and rural areas. The prevalence of dental caries was 33.5%, the decay missing filling tooth rate was 0.67, the gingival bleeding rate was 61.3% and the calculus rate was 55%. These rates of fluorosis were higher than those of non-fluorosis. The self-evaluation of fluorosis adolescents influenced social interaction, and teeth grinning was more affected than non-fluorosis.Conclusion The prevalence of dental fluorosis in Tianjin is mild, and public health measures are necessary to control the concentration of fluoride in water. The preva-lence of dental caries is high, especially in the first and second permanent molars. Professional oral health preven-tion for fluorosis adolescents should be strengthened, and further actions on oral health promotion are necessary.

Key words: dental fluorosis, random sampling survey, decay missing filling tooth, oral health education
