BACKGROUND/AIM: Injuries to the primary dentition affect children's esthetics, function, and mental health. They may also affect the development of the permanent teeth. The knowledge of dentists about deciduous tooth trauma is rarely evaluated. The aim of this study was to evaluate the knowledge and attitude of dentists in China regarding traumatic dental injuries to primary teeth.
A self-administered online questionnaire containing questions on demographic data and knowledge based on a clinical scenario was given to a purposive sample of dentists, recruited by a non-probability convenience sampling method. The chi-square test was used for statistical analysis, with the significance level set at P <.05.
A total of 394 out of 409 dentists provided valid data. There was no significant difference in demographic data. Questions about the treatment of hard dental tissue injuries in primary teeth presented a correct-response rate of 66.4%, with the highest correct-response rate for enamel fracture (n = 368, 93.4%) and lowest for complicated crown-root fracture with pulp exposure (n = 104, 26.4%). Questions about treatment of luxation injuries in primary teeth presented a correct-response rate of 66.6%, with subluxation presenting the highest correct-response rate (n = 391, 99.2%). Factors associated with higher correct-response rates were specialist disciplines, educational qualifications, workplaces, experience of injured teeth treated, and educational experience about primary tooth trauma. No significant differences were found in the correct-response rates of dentists with different years of work experience. Lack of cooperation from children was considered a major obstacle for treatment. Special lectures and Internet courses were the most preferred methods of obtaining knowledge.
The results suggest that it is necessary to enhance dental trauma education for dentists in China. More attention needs to be paid to trauma in primary dentition to ensure adequate treatment for traumatized primary teeth.
背景/目的：乳牙外伤会影响儿童的美观、功能和心理健康，也可能影响恒牙的发育。但目前很少评估牙医对乳牙外伤的知识了解程度。本研究旨在评估中国牙医对乳牙创伤性损伤的知识和态度。
采用方便非概率抽样方法，对 409 名牙医进行了一项基于临床情景的问卷调查，内容包括人口统计学数据和知识。采用卡方检验进行统计分析，显著性水平设为 P <.05。
共有 394 名牙医提供了有效数据。人口统计学数据无显著差异。在治疗乳牙硬组织损伤的问题上，正确回答率为 66.4%，其中釉质裂伤的正确回答率最高（n = 368，93.4%），复杂冠根折伴牙髓暴露的正确回答率最低（n = 104，26.4%）。在治疗乳牙脱位伤的问题上，正确回答率为 66.6%，其中半脱位的正确回答率最高（n = 391，99.2%）。与更高的正确回答率相关的因素包括专科、教育程度、工作场所、治疗过的受伤牙齿的经验以及关于乳牙创伤的教育经验。不同工作年限的牙医正确回答率无显著差异。儿童不配合被认为是治疗的主要障碍。专题讲座和互联网课程是获取知识的最受欢迎方法。
结果表明，有必要加强中国牙医的牙外伤教育。需要更多关注乳牙外伤，以确保对受伤的乳牙进行充分的治疗。
