Prevalence of traumatized permanent incisors in Jordanian children, according to age, sex and socio-economic class.
The purpose of this retrospective study was to analyse firstly the prevalence of firsty fractured permanent incisors, secondly their distribution according to age, sex and socio-economic class and thirdly the location of the trauma, in a population sample of schoolchildren from Jordan. The sample consisted of 3041 children aged 7-12 years enrolled in 6 public and private schools from the city of Amman and its outskirts. The prevalence of fractured permanent incisors was 10.5% (12.1% in boys and 8.8% in girls). The largest number of injuries was observed in the 11-12 years group (15.0%) and there was an increase of the prevalence of trauma associated with the increase of age. Significantly more boys suffered injuries than girls (P less than 0.01). The teeth most commonly injured were the maxillary central incisors (79.1%) and 85.2% of children sustained one fractured tooth only. The numbers of traumatized children in each of the low and middle socio-economic classes were significantly higher than those in the high socio-economic class.
