Objectives: This study aimed to conduct an epidemiological study of the prevalence and aetiology of traumatic dental injuries (TDI) in a sample of students aged 15 to 18 years resident in Kaohsiung City, Taiwan. A special interest was to identify the role of factors such as socio-economic status (SES), family structure, physical fitness and risk taking behaviour. It was hypothesised that adolescents experiencing TDI tended to have a lower SES, tended to live with non-birth parents, performed more risk taking behaviours and were less fit.

Material and Methods: A random sample of 6,504 fifteen-to-eighteen-year-olds from all senior high schools in Kaohsiung City, Taiwan, was selected. Each completed a supervised questionnaire and was examined using standard clinical procedures.

Results: The participation rate was 90.4%. Those participants that were male (OR=1.64, 95% CI: 1.43, 1.88), that lived with at least a non-birth parent (OR=1.28, 95% CI: 1.01, 1.63), that had a family head with a secondary level of education (OR=1.29, 95% CI: 1.11, 1.51), that had a higher Adolescent Risk Taking Scale score (OR=1.06, 95% CI: 1.04, 1.09), that had an overjet larger than five millimetres (OR=1.66, 95% CI: 1.41, 1.95), or that showed inadequate lip coverage (OR=1.36, 95% CI: 1.19, 1.55), were at greater risk of TDI. The prevalence of TDI was 20.0% (95% CI: 19.1%, 21.1%). Main causes of TDI were sports and leisure accidents (23.8%), followed by eating (15.8%), falls (15.3%), traffic accidents (7.6%), collisions (5.6%), inappropriate use of teeth (3.8%) and violence (2.9%). Up to 22.2% of TDI had unknown causes. II

Conclusions: In this study, risk taking behaviour was the leading determinant of TDI, greater than gender, family structure, family head's level of education, overjet and lip coverage. The prevalence of TDI in Taiwan was similar to that found in other countries. Sports and leisure accidents were the most common cause of TDI.
