Surgimed Med Dent J Jan ;1(2):14-7.

Objective: To investigate and understand the association between Traumatic Dental Injuries (TDI) and overjet in 14 year old children attending secondary schools in East London. Study Design: Cross-sectional survey design. Place of study: Data for this study was previously collected in 2002-03 by a Primary Care Trust in East London. Material and Methods: A total of 295, fourteen year old school children were included in the sample. The examiner recorded TDI to upper and lower incisors as well as the size of overjet. Following the clinical examination, participants completed a questionnaire which included information regarding how, when, where and what caused the TDI. Data analysis was done using SPSS version 12.0 and included descriptive statistics which was frequency distribution and cross-tabulation. Results: The results of the Chi-square analysis demonstrated TDI to be strongly associated with gender and increased overjet. Males (30.6%) had a higher prevalence of TDI than females (23.1%) and this was statistically significant (P=0.038). A child with increased overjet of more than 5mm was also found more likely to have TDI (42.7%) (P<0.001) Conclusion: These results bring us to the conclusion that traumatic dental injuries are associated with gender and overjet.
