Prevalence and causes of fractured permanent incisors in 12-year-old suburban Nigerian schoolchildren.
The aim of the study was to assess the prevalence and causes of traumatic dental injuries to the permanent dentition of 12-year-old school children in Ile-Ife, a suburban population in the south west of Nigeria. A dental trauma cross-sectional survey was carried out through clinical examination of upper and lower permanent incisors and interviews with 415 (212 boys, 203 girls) 12-year-old children attending private and public secondary schools in Ile-Ife, in 2004/2005 by one calibrated examiner. Garcia-Godoy's classification was used. The prevalence of traumatic dental injuries was 12.8%. There was no statistical difference in the prevalence between boys and girls P > 0.05. The most common cause of injuries was falls (49.1%), followed by traffic accidents (13.2%), collision against objects or people (11.3%) and misuse of teeth 9.4%. The commonest type of injury was enamel fracture alone (9.9%), followed by enamel-dentine fracture (4.8%). Majority of the accidents occurred at home (60.4%), followed by school (26.4%). The prevalence of traumatic dental injuries was on the increase among suburban Nigerian children in Ile-Ife and it has a potential to be considered an emerging public health problem.
