OBJECTIVES: This study sought to determine the prevalence of esthetic problems due to dental @entity3296 , and determine the relationship of different @entity1388 exposure histories to the occurrence of these problems. METHODS: In 1993-94 2,715 @entity1 in grades 2 and 3 and 3,297 adolescents in grades 8 and 9 were examined by four dentists. Questionnaires detailing exposures to various @entity1388 technologies were collected from 3,022 of these study @entity1 . Esthetic ratings of the @entity1 ' @entity1347 were made by the examiners, the @entity1 themselves, and their parents using questionnaires designed for this purpose. RESULTS: Data indicate that 46 percent of the @entity1 had dental @entity3296 . Only 40 percent had @entity3296 on anterior maxillary teeth. The prevalence of esthetic problems ranged from about 1 percent to 4 percent, depending on how an esthetic problem was defined. Esthetic problems as defined by the @entity1 were more prevalent for the "over 11" age group. Logistic regression results demonstrated significant associations between several of the classifications of esthetic problems and the use of @entity1388 supplements and dentifrices, and exposure to fluoridated water during the third year of life. CONCLUSIONS: Results suggest that the prevalence of esthetic problems is low in the communities surveyed, and that exposure to any number of @entity1388 technologies in the third year of life can increase a @entity1 's risk for this problem.
