Trauma to anterior teeth in children could become a long-term problem to dental health. 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.
儿童前牙外伤可能会成为影响牙齿健康的长期问题。在很大程度上，相关牙医的处理措施将决定临床结果，而这些措施又与他们的知识水平相关。本研究的目的是调查牙医对儿童上颌恒切牙外伤处理的知识掌握情况。一份包含19个关于牙齿外伤治疗管理方法问题的自填式问卷被邮寄给了澳大利亚维多利亚州的693名牙医。回复率为61%。这项调查发现，一些受访者对不同类型的外伤有足够的处理知识，而另一些人则没有正确的信息。大约一半的牙医认为牛奶是脱出牙齿首选的口外储存介质，再植后应固定7 - 10天。很大一部分牙医在理解导致替代性牙根吸收（61%）和外部炎性牙根吸收（74%）的生物学机制方面知识不足。总体而言，本次调查的受访者在儿童上颌恒切牙外伤处理方面仅表现出中等水平的知识。持续专业发展项目可能是改善这一知识短板的一种方式。
