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.
这项回顾性研究的目的是，首先分析约旦学龄儿童样本中恒牙列切牙外伤的患病率，其次分析其按年龄、性别和社会经济阶层的分布情况，第三分析外伤发生的部位。样本包括安曼市及其郊区6所公立和私立学校的3041名7至12岁儿童。恒牙列切牙外伤的患病率为10.5%（男孩为12.1%，女孩为8.8%）。受伤人数最多的是11至12岁年龄组（15.0%），且外伤患病率随年龄增长而增加。男孩受伤人数明显多于女孩（P<0.01）。最常受伤的牙齿是上颌中切牙（79.1%），85.2%的儿童仅一颗牙齿受伤。社会经济阶层低和中等的儿童外伤人数显著高于社会经济阶层高的儿童。
