| pubmed-article:8957837 | pubmed:abstractText | The aim of this study was to investigate the prevalence, aetiology and types of injuries to permanent incisors among 459 Jordanian schoolchildren aged 10-12 years, 234 from urban Amman and 225 from rural South Shouna. The prevalence of injuries in Amman was 19.2% (23.9% in boys, and 14.9% in girls) and in South Shouna 15.5% (19.1% in boys and 12.2 in girls). Significantly more boys than girls suffered injury. The difference in prevalence between urban and rural children was not statistically significant. The most common type of injury in both communities was enamel fracture, and the most common causes of injury were falls and collisions with other children. Children with an overjet greater than 5 mm sustained significantly more injuries to the incisor teeth than children with normal overjet. | lld:pubmed |
