青岛市口腔医生对乳牙牙外伤处理的认知调查

目的研究青岛地区口腔医生对乳牙牙外伤处理的认知水平。 方法利用2018年8月青岛市儿童口腔疾病预防公益项目培训会议期间，向参会医生发放经过验证的调查问卷，进行乳牙牙外伤处理认知调查，使用χ²检验对结果进行统计分析。 结果调查相关口腔医生170名，共回收有效调查问卷168份（98.8%）。结果分析：青岛地区口腔医生对乳牙折断性损伤处理方案选择的正确率为53.57%，对乳牙牙脱位性损伤处理方案选择的正确率为72.62%，对乳牙全脱位处理方案选择正确率为58.33%。卡方检验显示，不同医疗机构和不同职称的口腔医生在大多数问题的选择正确率上没有明显差异（P>0.05），第7、9、11、13题中，儿童口腔医生对乳牙外伤处理方案选择正确率分别为88.9%、55.6%、97.2%和91.7%，非儿童口腔医生选择正确率分别为67.2%、13.7%、76.2%和81.1%，差异均具有统计学意义（χ²⁷ = 6.844，P₇ = 0.009；χ²⁹ = 17.3，P₉<0.001；χ²¹¹ = 9.056，P₁₁ = 0.003；χ²₁₃ = 2.291，P₁₃ = 0.130）。 结论青岛市口腔医生对乳牙牙外伤处理方案的选择整体正确率较低，不同的医疗机构和不同职称的口腔医生在处理方案的选择上没有明显差异，儿童口腔医生对乳牙外伤处理方案选择的正确率更高。

Evaluation of knowledge among dentists in treatment of traumatic injuries in primary teeth in Qingdao

ObjectiveThe purpose of the present study was to assess the knowledge of dentists in Qingdao regarding the management of dental traumatic injuries of primary teeth. MethodsDuring the training meeting of Qingdao children′s oral disease prevention project in August 2018, a validated questionnaire was distributed to participating doctors to conduct a cognitive survey on the management of primary teeth trauma. The chi-square test was used for statistical analysis of the results. Results170 dentists were investigated and 168 questionnaires were collected (98.8%) . The results showed that the correct selection of the treatment plan for the fracture injury of primary teeth by the dentists in Qingdao was 53.37%. The accuracy of the treatment for the luxation injury of primary teeth was 72.62%. while which was 58.33% for the primary teeth avulsion. Chi-square test results showed that, there was no significant difference in the correct rate of most questions between different medical institutions and dental doctors with different professional titles (P>0.05) . In questions 7, 9, 11 and 13, the correct rate of Pediatric dentists in choosing the treatment plan for primary teeth trauma was respectively (88.9%, 55.6%, 97.2%, 91.7%) , and those of Non-pediatric dentists were 67.2%, 13.7%, 76.2%, 81.1% respectively. The differences were statistically significant (χ²⁷=6.844, P₇=0.009; χ²₉=17.3, P₉<0.001; χ²₁₁=9.056, P₁₁= 0.003; χ²₁₃=2.291, P₁₃=0.130) . ConclusionsThe overall accuracy of the treatment for primary teeth trauma among dentists was low in Qingdao. There was no significant difference between different hospitals and dentists with different professional titles. Pediatric dentists were more likely to have a higher rate of accuracy choice in treatment options for luxation injury and avulsion.
