Abstract

Introduction: The most common reasons for dental traumas during childhood and adolescence are falling, accidents and sporting events. The most frequently traumatized teeth are anterior teeth, leading to eating problems and unpleasant psychological effects. The aim of this study was to assess frequency of dental injuries, cause of these injuries and treatments rendered based on Iran Insurance Company files. Materials and Methods: In this descriptive/analytical study 400 files related to dental traumas of 7-12-year-old children were randomly selected from children injury files in Isfahan in 2010-2011, and the demographic data along with data on the traumatized teeth, etiology of trauma and the treatment rendered by the dentist were collected. Data were analyzed by SPSS 16 using descriptive statistical tests. Results: Frequency of dental injuries in governmental schools (75%) was higher than that in non-profit schools (25%) and higher in boys compared to girls. In addition, more injuries were found in the 10-12 age group in comparison with the 7-9 age group. The most frequently traumatized teeth were maxillary right central incisors and the most common etiology of trauma was sporting accidents. In 91.3% of cases, the tooth crown was fractured and in 14.2% of cases the root was fractured, with or without crown fractures. Filling (81.1%) was the most common treatment received and 17.4% of traumatized teeth had been extracted; 87.3% of injuries had been treated by general dentists and the remainder by specialists. Conclusion: Based on the results, gender and age were predisposing factors for dental trauma. The most frequently traumatized teeth were maxillary central incisors and the most frequent injury was crown fracture and filling was the most frequent treatment received.   Key words: Epidemiology, Etiology, Injuries, Treatment
