上海市某卫校学生口腔卫生习惯与患龋状况的调查分析

目的 建立17～19岁学生龋齿发病基线资料,探讨龋病与口腔卫生习惯等相关性。方法 采用WHO标准检查1027名女学生牙齿,以DMFT评价龋状况,同时对学生进行口腔卫生习惯问卷调查。结果 学生患龋率为54％,DMFT为1.3;龋病与每日刷牙次数、每次刷牙所用时间及牙齿软垢指数没有显著相关性,而与经常使用含氟牙膏有显著相关性(P<0.05);有睡前吃零食习惯和经常喝碳酸饮料者在患龋人群中的比例明显高于非龋人群(P<0.01);刷牙时出血者在有龋人群中的比例低于无龋人群(P<0.01);认为定期检查无所谓及治疗时疼痛者在有龋人群中的比例高于无龋人群;认为无必要定期检查及牙病能够忍受者在无龋人群中的比例高于有龋人群(P<0.01);评价自身牙齿健康者在无龋人群中的比例高于有龋者;对自身牙齿不满意者在有龋人群中的比例高于无龋者(P<0.01)。结论 加强学生口腔卫生观念、改变不良生活习惯和口腔卫生习惯,有益于降低龋齿发病率。

An Investigation of Oral Health Habits and Dental Caries of Students from a Health School in Shanghai

Objective To collect the information of pathogenic base line of dental caries of students in the Health School attached to Shanghai Second Medical University and to explore the correlation between dental caries and oral health habits. Methods Standards of WHO were adopted to examine the teeth of 1 027 female students and DMFT was applied to estimate the dental caries condition. The students were asked to finish an oral health habit investigation questionnaire. Results The dental caries rate of the school was 54% , while DMFT was 1.3. There existed no significant difference ( P > 0.05) . Based on dental caries, daily brushing frequency, brushing times and teeth dirt index, there existed significant difference among the persons using fluoride toothpaste ( P < 0.05) . Those who had the habit of snacking and drinking carbonate drinks before sleeping suffered from more dental caries than those without it(P<0.01). Those with dental caries were fewer than those without them. Brushing teeth with toothbleeding happened more in those with dental caries than those without it ( P < 0.01) . Periodic oral examinations and oral pain occurrence were thought of no importance in more with dental caries than those with it. Periodic oral examinations and oral pain tolerance were thought unnecessary in more without dental caries than those with it. Those with no dental caries evaluated their teeth health more than those with it. Those with dental caries were more dissatisfied with their teeth health than those without it( P < 0.01) . Conclusion It was helpful to decrease the student morbidity of dental caries by strengthening the students' sense of oral hygiene and by changing the bad living habits and oral health habits.
