青岛市市南区小学教师对学龄儿童外伤全脱出牙应急处理的认知水平调查

目的了解青岛市市南区小学教师对学龄儿童外伤全脱出牙应急处理的认知水平现状。 方法2019年3—4月，利用青岛市第一次口腔流行病学调查的机会，采用分层随机抽样的方法，抽取青岛市市南区12所小学597名小学教师，对其进行问卷调查，应用卡方检验对结果进行统计分析。 结果本调查共回收有效问卷540份，85.9%教师为女性，15.2%的教师接受过牙外伤相关教育，89.6%的教师没有见过外伤全脱出牙。15.2%的教师知道全脱出牙齿的正确紧急处理方式；对全脱出牙采用良好保存介质的教师，58.7%选择0.9%氯化钠溶液，8.3%选择牛奶，6.3%选择含在孩子口中；关于全脱出牙的就诊时间，认为应该即刻就诊的教师人数比例为56.5%。86.9%的教师问卷得分低于4。不同教龄教师间问卷得分差异有统计学意义（χ² = 9.445，P = 0.002），是否接受过牙外伤教育的教师间问卷得分差异也有统计学意义（χ² = 13.148，P<0.001）。 结论青岛市市南区小学教师对学龄儿童外伤全脱出牙应急处理认知水平不高，应加强小学教师牙外伤知识的宣教。
