Little new evidence on the prevalence of injury to the anterior teeth of children has been reported in the past five years and, in South Africa, trauma to the teeth of children in different ethnic groups has not been compared respectively. The purpose of this investigation was to determine the prevalence of dental trauma using well-defined criteria and to sample a specific age-group. Five regions were chosen and 1035 children in the eleven-year age-group were examined. No statistical significance was found between the ethnic groups related to the amount of injury sustained. For all groups, boys received more injuries than girls. The most common injury was fracture of the enamel of the maxillary central incisor. With 15 percent of the children receiving some level of trauma by age eleven years, this is one of the main dental treatment needs for South African children.
在过去五年里，关于儿童前牙损伤患病率的新证据报道很少，而且在南非，尚未分别比较不同种族儿童牙齿的外伤情况。本调查的目的是使用明确的标准确定牙齿外伤的患病率，并对特定年龄组进行抽样。选择了五个地区，对1035名11岁年龄组的儿童进行了检查。在各民族之间，就所遭受的损伤程度而言，未发现统计学上的显著差异。对于所有组，男孩比女孩受伤更多。最常见的损伤是上颌中切牙牙釉质骨折。到11岁时，15%的儿童受到了某种程度的外伤，这是南非儿童主要的牙齿治疗需求之一。
