To a large extent, the management actions of the dentists involved will determine the clinical outcome and, in turn, these actions will be related to their levels of knowledge. The aim of this study was to investigate dentists' knowledge of managing traumatic injuries to maxillary permanent incisors in children. A self-completion questionnaire containing 19 questions on management methods of treating dental trauma was mailed to 693 dentists in Victoria, Australia. The response rate achieved was 61%. This survey found that some of the respondents had adequate management knowledge for the different types of traumatic injuries, while others did not have the correct information. Approximately half the dentists considered milk as the preferred extraoral storage medium of choice for avulsed teeth and a period of 7,10 days splinting after replantation. A large proportion of dentists showed inadequate knowledge with regard to understanding the biological mechanisms causing replacement root resorption (61%) and external inflammatory root resorption (74%). Overall, the respondents to this survey demonstrated only a moderate level of knowledge in management of traumatic injuries to maxillary permanent incisors in children. Continuing professional development programmes may be a means of improving this deficient knowledge base. [source]

Background.,, Dental trauma is common among children, and the maxillary permanent central incisors are the most often affected teeth. Aim.,, This study aimed to investigate the risk factors for injury to maxillary permanent incisors and the upper lip among Tanzanian schoolchildren aged 8,14 years. Design.,, A cross-sectional study involving 1119 children. The risk variables investigated included age, gender, lip competence, and overjet. The corresponding proportions of injuries and the relative risk (with 95% confidence interval) were calculated and tested by Fisher's exact test. Logistic regression was applied to ascertain the strength and direction of the association of the risk variables to injuries, and backward selection was used to test significant risk factors. Results.,, About 24% of the children had trauma to maxillary incisors, 45% had incompetent lip whereas 31% had increased overjet. Age, gender, overjet, and lip competence showed significant association with injuries to upper lip and maxillary incisors. Boys had sustained more injuries than girls, with a higher relative risk for luxation injuries. Enamel fracture was associated with overjet combined with lip competence, whereas enamel dentine fracture without pulp involvement was related to gender. Luxation injuries were associated with gender, tooth avulsion with overjet, and lip competence. Injury to the upper lip was associated with age. Conclusion.,, Male gender, increased overjet, and lip incompetence were the main risk factors of getting trauma to maxillary incisors, whereas age was the risk factor for injury to the upper lip.
