This study evaluated the prevalence of dental trauma for patients attending the emergency dental clinic at the University of Alberta Hospital between 2006-2009. Patients’ examination and treatment charts were reviewed.
Total number of patients’ charts was 1893.The prevalence of different types of trauma was 6.4 % of the total cases (117 patients). Trauma cases were identified according to Ellis classification and as modified by Holland et al., 1988.
Logistic statistical model showed that 21.7% were Ellis class I trauma, 16.7% were Ellis class II trauma, and 6.7% were Ellis class III. In addition, 11.7 % presented with avulsion, 7.5 % presented with dentoalveolar fracture and 7.5% presented with sublaxation. Also, 17.55 % presented with tooth displacement within the alveolar bone, 3.3 % presented with crown fracture with no pulp involvement, 4.16 % presented with crown fracture with pulp involvement and 3.3 % presented with root fracture. In conclusion, the general prevalence of dentoalveolar trauma in patients attending the emergency clinic at the University of Alberta is less than other reported percentages in Canada or other countries.
