Abstract
Objectives: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.Methods: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.Results: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.
Highlights
To establish prospective treatment modalities and public awareness of potential causes and consequences of dentoalveolar trauma, it is very important to establish provincial, national and international prevalence of dental trauma and its causes
The present study presents a relatively low prevalence of dental trauma, but still this low percentage represents a large number of patients
This study suggests initiation and implementation of public awareness studies that aims towards prevention and potential treatment strategies of dentoalveolar traumatic injuries
Summary
To establish prospective treatment modalities and public awareness of potential causes and consequences of dentoalveolar trauma, it is very important to establish provincial, national and international prevalence of dental trauma and its causes. Previous reports on the prevalence of dental trauma showed different percentages of dental trauma in different parts of the world. Reports on the prevalence of dental trauma in 519 children between ages of 6 to -11 years old in Italy was 21% with male/female ratio of 1.69 [1]. Petti et al.1996 reported that higher dentoalveolar trauma prevalence was among the 9 year-old children (26.9%) compared to other age groups with enamel fractures being the most frequent trauma type (67.0%), followed by enamel-dentine fractures (19.3%) and concussions (8.3%). Another report on the prevalence of dental trauma in Sweden in children between 7-17 years old showed that the prevalence was 11.7% with a
