Comparison of Dentoalveolar Trauma Patterns Between E-Scooter and Bicycle Accidents in a German Urban Area: A Retrospective Study

<b>Objectives:</b> The increasing popularity of electric scooters (E-scooters) has led to a rise in trauma-related injuries, particularly in the craniofacial region. This study aims to compare dentoalveolar trauma (DT) patterns between E-scooter and bicycle accidents in a German urban area to identify differences in injury characteristics, risk factors, and treatment approaches. <b>Materials and Methods:</b> This retrospective study analyzed 178 patients treated for DT following E-scooter (n = 56) or bicycle (n = 122) accidents between January 2022 and December 2022 at a single oral and maxillofacial surgery department in a German urban area. Demographic, clinical, temporal, and therapeutic data were collected and statistically compared. <b>Results:</b> E-scooter patients were significantly younger (mean age: 33.6 vs. 47.0 years, <i>p</i> < 0.001) and predominantly female (85.7% vs. 26.2%, <i>p</i> < 0.001) compared to bicycle patients. E-scooter accidents more frequently occurred at night (69.6%) and on weekends (62.5%) and were significantly associated with alcohol consumption (55.4%) and low helmet use (8.9%). Clinically, E-scooter accidents resulted in more complex dental injuries, including a higher incidence of root fractures (14.3% vs. 0%, <i>p</i> < 0.001), complicated crown fractures (25.0% vs. 9.0%, <i>p</i> = 0.004), and crown-root fractures (32.1% vs. 9.8%, <i>p</i> < 0.001). Mandibular injuries were more prevalent in the E-scooter group, and concomitant facial fractures (excluding alveolar) were also more common (28.6% vs. 19.7%, <i>p</i> = 0.018). <b>Conclusion:</b> E-scooter accidents are associated with a distinct DT pattern involving younger, often alcohol-intoxicated, and helmetless patients, typically presenting with more severe and complex DT-injuries. These findings highlight the urgent need for targeted prevention strategies, legislative measures on helmet use, and clinician awareness of specific trauma profiles linked to E-scooter use.
