Information on previous traumatic dental injuries is important as they can lead to increased complications during orthodontic treatment and impact the treatment planning and outcomes. The aim of this study was to assess the knowledge of Jordanian orthodontists in orthodontic management of traumatized permanent teeth. Cross-sectional survey among active registered orthodontists using a questionnaire distributed by hand. The study included 139 orthodontists. Nearly half of orthodontists treated between one to three patients with a history of traumatic dental injuries in the past 3 months. Only 43.2% of the participant asked routinely about history of trauma. A vast discrepancy in times waited before orthodontic movement and in the orthodontic management approach of traumatized teeth was noted. A statistically significant negative relationship between age and knowledge level was found (p = 0.002). A significantly higher level of knowledge was found among participants who had fellowship or board certification than those having the high diploma degree (P-0.032) and also who had treated patients with history of dental trauma in the last 3 months than those who did not (p = 0.001). The knowledge of the surveyed orthodontists in both the recommended observation period before orthodontic treatment and management approaches of traumatized teeth during orthodontic treatment was insufficient. Years of clinical experience significantly affected knowledge, with older participants having lower levels of knowledge. Orthodontists who treated patients with history of dental trauma in the last 3 months had significantly higher knowledge in orthodontic management of traumatized teeth. Orthodontists needs to be aware of the proper timing and strategies on orthodontic management of traumatized permanent teeth to improve the long term prognosis and to reduce further complications during orthodontic treatment through proper management.
