OBJECTIVES. To investigate the level of knowledge about emergency management of dental trauma among Hong Kong primary and secondary school teachers. DESIGN. Questionnaire survey. SETTING. A teachers' union that unites 90% of teachers in Hong Kong. PARTICIPANTS. Randomly selected primary and secondary school teachers. RESULTS. Only 32.8% of respondents correctly stated that a person sustaining dental trauma should go to dentists directly. In all, 73.1% of teachers correctly stated that a dental trauma patient should go for treatment immediately. Only 32.5% knew that a fractured tooth should be put in liquid. Even fewer (23.2%) realised that the displaced tooth should be repositioned back to the original position. Relatively more respondents (74.7%) understood that an avulsed baby tooth should not be put back. Disappointingly, only 16.3% of teachers knew that an avulsed permanent tooth should be replanted. Furthermore, only 29.6% of teachers thought that they were able to distinguish between deciduous teeth and permanent teeth, whilst 20.4% correctly identified at least one of the appropriate mediums: milk, physiological saline or saliva, for storing an avulsed tooth. Teachers who previously received first-aid training with dental content or acquired dental injury information from other sources, scored significantly higher than teachers without such training or acquired information. CONCLUSION. The knowledge on emergency management of dental trauma among primary and secondary school teachers in Hong Kong is insufficient, particularly on the handling of permanent tooth avulsion and the appropriate storage medium for avulsed teeth. Receipt of first-aid training with dental contents and acquisition of dental injury information from other sources were positively correlated with knowledge in managing dental trauma.
目的。调查香港中小学校教师对牙科创伤急救管理的认知水平。设计。问卷调查。地点。团结了香港 90%教师的教师工会。参与者。随机抽取的中小学教师。结果。只有 32.8%的受访者正确指出，发生牙外伤者应直接去看牙医。总共 73.1%的教师正确指出，牙外伤患者应立即就医。只有 32.5%的人知道应将折断的牙齿放入液体中。更少的人（23.2%）意识到应将脱位的牙齿复位到原来的位置。相对较多的受访者（74.7%）明白应将脱位的乳牙不拔回。令人失望的是，只有 16.3%的教师知道应将脱位的恒牙再植。此外，只有 29.6%的教师认为他们能够区分乳牙和恒牙，而 20.4%的教师正确识别了至少一种合适的储存介质：牛奶、生理盐水或唾液，用于储存脱位的牙齿。接受过含牙科内容的急救培训或从其他来源获取过牙科损伤信息的教师，得分显著高于未接受过此类培训或获取过此类信息的教师。结论。香港中小学校教师对牙科创伤急救管理的知识不足，尤其是对恒牙脱位的处理和脱位牙的合适储存介质。接受过含牙科内容的急救培训和从其他来源获取过牙科损伤信息与处理牙科创伤的知识呈正相关。
