ABSTRACT

The number of reported traumatic injuries has been increasing in recent years, particularly that of dentaltrauma in children and adolescents. While the risks associated with dental trauma in this population have beenincreasingly realized, domestic reports on this issue seem to be insufficient. The purpose of this study was to investigate the prevalence of dental trauma and to evaluate the relevant riskfactors and the level of self-recognition. 1,371 adolescents attending middle schools at Yangsan were surveyedvia clinical examination and questionnaire; the results were as follows:According to the clinical examination, the overall prevalence of dental trauma was 16.8% with preponderanceof males (19.2%) compared to females (13.7%) (p < 0.05). The average number of injured teeth per adolescentwith a history of trauma was 1.34. Comparing the prevalence, maxillary central incisors and enamel fractureoccupied the highest ranks by tooth type and mode of trauma, respectively. Class II division 1 malocclusion andoverjet exceeding 8.0 mm were identified as significant risk factors (p < 0.05). The degree of self-recognition ofdental trauma showed a low coincidence rate compared with results of the clinical examination. Males expresseda higher level of satisfaction toward the results of treatment for dental trauma than females (p < 0.05).
