Abstract Introduction: Treatment and follow up of traumatized teeth has ever been the concern of many dentists throughout the world. The matter sounds more concerning when the traumatized tooth is a permanent anterior tooth. Regarding to the importance of anterior permanent teeth in mastication, speaking and esthetic, and high prevalence of crown fracture in traumatic injuries of the permanent teeth, we decided to do this study. Objective: The aim of this study is to survey the etiology and prevalence of crown fracture of anterior permanent teeth in 2nd-5th grade children of primary school in Rudsar. Materials and Methods: The study was done by a descriptive and cross-sectional method. The sample consisted of 700 students of 2nd - 5th grade of primary school were randomly selected from 21 schools in Rudsar. Examination was done in natural light and the information about types of crown fracture, number of traumatized tooth, rate of over jet and over bite, lip seal, etiology of trauma and if treatment, registered in a questionnaire. The data were analyzed with SPSS software and Chi-Square test. Results: The prevalence of crown fracture among anterior teeth was 10.3%. The ratio of male to female patients was 1.1/1 Maxillary central incisors were most affected (83.5%) and the most common type of crown injury was enamel fracture (76.4%). Most injuries occurred at home (50%) and in summer (37.4%). Falls were the most frequent cause of dental trauma (37.5%). There was a tendency for children with an increased over jet, deep bite, open bite and lip incompetency to have experienced dental injuries. Conclusion: Considering the importance of anterior teeth and more frequency of trauma in summer, preventive education programs should be instituted in the region, directed at parents and schoolteachers, to inform them about the problems of dental trauma and to obtain cooperative attitude in treatment and good motivation.
