上海五个区小学卫生教师对儿童牙外伤了解程度的调查与分析

Survey and analysis of elementary school health teachers' knowledge about children's dental trauma in five districts of Shanghai

目的调查上海五个区小学卫生教师对儿童牙外伤的了解程度,并分析其影响因素。方法采用随机抽样的方法,从上海所有19个区县中随机抽取5个区,对这5个区所有小学共306名卫生教师进行关于儿童牙外伤的问卷调查,用构成比及卡方检验对结果进行统计分析。结果在调查的5个区中一共收到了301份有效的卫生教师问卷。61.8%的教师表示接触过牙外伤;接受过专门关于牙外伤教育的教师人数比例为34.3%。3.7%的教师选择对全脱位牙齿进行即刻再植;对全脱位牙齿采用湿性保存媒介的教师有9.0%(含在口中)、45.5%(放在盐水中)1、8.3%(放在牛奶中);关于全脱位牙齿的就诊时间,认为应该在30 min内治疗的教师人数比例为46.8%。结论上海五个区小学卫生教师对儿童牙外伤的了解仍十分有限,今后需要加大对这类人群关于儿童牙外伤的宣传力度。

Objective This study was designed to assess the knowledge and analyze the possible affecting reasons of the elementary school health teachers in five districts of Shanghai about children＇ s dental trauma. Methods Five dis- tricts were randomly sampled from all nineteen districts in Shanghai （including urban and rural areas）. All of the elementa- ry school health teachers in these districts, 306 in total, were surveyed about children＇ s dental trauma voluntarily. The questionnaires were recycled and analyzed using constituent ratio and chi-square test. Results Our survey received a total of 301 valid questionnaires in five districts. According to the statistical results, 61.8% of the teachers have met children＇ s dental trauma. The proportion of health teachers who have received special education on dental trauma is 34.3%. For the avulsion case, very few health teachers （3.7%） will choose to put the avulsed tooth back into the alveolar pocket. When choosing the storage media for avulsed tooth, 18.3% of the health teachers choose milk; 45.5% of the health teachers choose physiological Saline ; 9.0% of the health teachers choose to let the child put the avulsed tooth in mouth. As for the extra-oral time for avulsed tooth, 46.8% of the teachers think that the avulsed tooth should be treated within half an hour. Conclusions This study showed that although elementary school health teachers faced children＇ s dental trauma, they actually showed poor knowledge regarding this area. The survey reinforces the need for educational campaigns to edu- cate elementary school health teachers about children＇ s dental trauma in our future work.
