Abstract:


Purpose: Traumatic dentoalveolar injuries (TDI) affect approximately 4.5% of the population annually. This 13-year retrospective review examined TDI trends at a pediatric hospital and level-one trauma center in Columbus, OH.



Methods: Children ≤18 years with TDI (Jan 2012–Dec 2024) were identified via Epic electronic health records. Mechanisms of injuries (MOI) were classified into 15 categories and 6 sports subcategories. Trends in mechanism, dentition, and demographics were analyzed.



Results: In total, 7,147 TDI encounters, 4,416 (62%) males and 2,731 (38%) females, were included. Mean age at time of TDI was 7.99 years (SD 4.46). Permanent TDI (4,729, 66%) exceeded primary (2,418, 34%). The most common MOI in the permanent dentition was fall (2,106, 45%), followed by hit by object (767, 16%), and sports injury (652, 14%). The most common MOI in the primary dentition was fall (1,957, 81%) followed by hit by object (206, 9%), and bicycle (83, 3%). Basketball (233, 36%) was most common sports injury in the permanent dentition, followed by baseball/softball (146, 22%) and football (72, 11%). Total numbers of TDI increased from 287 in 2012 to 793 in 2024.



Conclusions: TDI rates significantly increased from 2012 to 2024. While new etiologies like trampoline or scooters emerge, falls continue to be the most common MOI. Males experienced more TDI than females. Permanent dentition injuries predominated in this population. Basketball was the most common sports injury. Evolving trends in TDI and increasing population highlight the importance of new and informed prevention strategies.
