Aim: Trauma to maxillary anterior teeth is a common reason for emergency room visits among children; therefore, the goal of this study was to evaluate the prevalence and related factors of such trauma among 9- to 14-year-old children in Yazd. Materials and methods: A sample of 1440 schoolchildren aged 9-14 years old, consisting of 720 boys and 720 girls, were randomly selected from 24 schools in Yazd. Ellis classification was used to record the dental injuries. Results: The prevalence found was 27.56%. The occurrence of trauma was significantly higher in male patients; furthermore, most of the dental trauma occurred in children between 9 and 10 years of age (47.38%). The most common type of injury was the 'enamel only' fracture; falls being the main cause of trauma. The most affected tooth was the maxillary central incisor Conclusions: The prevalence and most common causal factor of traumatic injuries to the maxillary anterior teeth in schoolchildren living in Yazd was approximately the same as that found in other countries.
