Traumatised Anterior Teeth In A Sample Of 12-13 Year-Old Malaysian Schoolchildren

Abstract

In Malaysia the School Dental Service (SDS) provides comprehensive dental treatment with the aim of rendering the child dentally fit before leaving primary school at 12 years. Hence the purpose of this study was to investigate I) the prevalence and treatment needs of traumatised permanent incisors and 2) to assess their relationship to the degree of incisor overjet amongst 12-13 year-old schoolchildren. The sample comprised of 1519 schoolchildren attending 20 secondary government and government-aided schools in Klang district. There were 772 boys and 747 girls. The sampling procedure involved a multistage, clustered and stratified random sampling. The prevalence of traumatic injuries in permanent incisors was 2.6% which confirmed the results of a previous local study. Boys suffered more trauma than girls with a ratio of about 1.5:I. A majority (77.5% ) of the children had one tooth affected. The most commonly affected teeth were the upper central incisors (91.8%) followed by the lower central incisors (4.1%). A high percentage (57.5%) of children with traumatised anterior teeth had increased overjet (>3mm). Almost all cases (93.9%) required two or more surface fillings. However the majority of affected children (56%) were satisfied with their appearance. It is concluded that traumatic dental injuries should be incorporated as part of the treatment plan for the SDS and appropriately managed soon after occurrence or not later than 12 years after which they leave the SDS. Future epidemiological studies should also give due emphasis to the relative importance of traumatised teeth in children.
