OBJECTIVES:The aim of this study was to evaluate etiology, types of traumatic dental injuries and their treatment in patients who referred to Yeditepe University, Faculty of Dentistry. METHODS:The study was based on the clinical data of the one hundred sixty one traumatized teeth in 92 patients (35(38%) girls and 56(72%) boys) with a mean age 7.6±3.5 (ranging 1 to 14,2) and the mean followed up 1.72±1.28 years. WHO classification for dental trauma was used. The etiology and localization of trauma, traumatized teeth classification, treatment and complications were evaluated both primary and permanent teeth. RESULTS:From the 161 teeth affected, 69(42.9%) were in primary teeth and 92(57.1%) in permanent teeth. The highest frequency of trauma occurred in the 6-12 year age group. Overall boys significantly outnumbered girls by approximately 1:1,6. The most common type of injury in the primary and permanent teeth was seen as luxation (38%) and enamel fracture (20%) of the maxillary central incisors, respectively. Falls were the major sources of trauma both the primary (90%) and the permanent teeth (84%). In the primary dentition, the most common type of soft tissue injury is contusion (62.5%) and in the permanent dentition, it is laseration (49%). The most of the treatment choice was determined as examination only and extraction in primary teeth (58% and 24.6%, respectively) while it was applied as restoration and pulpectomy in permanent teeth (31.5% and 18.5%, respectively). Complications were recorded on 37 teeth (23%) with a most common type of necrosis (10,5%) and dental abscess (7,4%). CONCLUSION:The study showed that boys were more prone to dental traumas than girls. Falls were more frequent trauma type with a high complication risk. It reveals that the time of the immediate treatment showed the important predisposing factors that increase the success of treatment and decrease the risk of complication.
