  To determine the etiology and types of TDIs among traumatized patients admitted to Gondar University Hospital Dental Clinic (GUHDC) between September 2013 and August 2015.
  
  
  
  A retrospective descriptive study design was conducted using previous medical records of 309 patients. Records were retrieved, reviewed and analyzed.
  
  
  
  A total of 309 dental traumatic patients with a mean age of 24.32±5.47 were admitted to the GUHDC. It was found that TDIs were most frequent in males (80.3%), 21-30 age range (47.2%) and rural residents (58.3%). Interpersonal violence (74.1%) and road traffic accidents (23.3%) were the most common etiological factors. The study also revealed that maxillary central incisor was the most frequently affected tooth.
