    Abstract:
    OBJECTIVE: The study was carried out to assess the prevalence of traumatic injuries to the permanent incisors of 14-year-old schoolchildren in Newham in 1998-99, the treatment needed and to compare the results with data from 1995-96. Also, to test whether different levels of deprivation within an area would increase the risk of dental injury. BASIC RESEARCH DESIGN: A cross-sectional study was carried out. One dentist (SM) carried out all dental examinations. Upper and lower permanent incisors were examined for dental injuries. The examiner recorded the type of damage sustained, any treatment carried out and the treatment need. PARTICIPANTS: 411 14-year-old schoolchildren in Newham in 1998-99. Results The prevalence of traumatic injuries was 43.8% (95% CI 39.0, 48.7) in 1998-99, compared to 23.7% (95% CI 22.0, 25.5) in 1995-96. Boys sustained statistically significantly more dental injuries than girls, 50.2% and 37.1% respectively (P<0.01). In 1998-99 92.7 per thousand incisors were damaged, 6.7 per thousand incisors were treated and 28.9 per thousand incisors needed treatment. Two components of the Jarman Index were associated with dental injuries. Overcrowded household was statistically significantly related to dental injuries in both studies. Ethnicity was associated with dental injury in 1998-99, but not tested in 1995-96. CONCLUSIONS The prevalence of traumatic dental injury in Newham increased from 23.7% to 43.8% between 1995-96 and 1998-99, it was higher than the overall prevalence in the United Kingdom (17%) and its treatment had been neglected. Area-based measures of deprivation such as an overcrowded household and ethnicity were predictors of traumatic dental injuries.
