Methods This cross-sectional study was carried out in three pub-lic kindergartens in Qingdao Shinan-Zone,China.The study consisted of 434 children aged 3 to 6. Caries statuses and the black stain on teeth were assessed by two calibrated dentists using WHO criteria. The questionnaires were done by parents,which included the time of children's brushing,the frequency of brushing and eating seafood,the use of antibiot-ics and so on. Data were analyzed using SPSS15.0 statistics software. Results The prevalence of black stain was 14.75% among these 434 children. There was no significant difference between male and female children. The caries prevalence of children with black stain was 43.5%,significantly lower than the children without black stain(62.7%,P<0.001).
