摘要
目的 调查中专学生第一恒磨牙的龋齿发生情况。方法 采用肉眼直视法 ,采取整群抽样的方法对 10 80名 15～ 2 0岁中专学生口腔中第一恒磨牙的龋齿发生情况进行检查并记录。结果 随年龄增长 ,男生第一恒磨牙的患龋率无明显变化规律 ,女生的患龋率呈增高趋势 ,三组同年龄段女生的患龋率均明显高于男生 ,且存在显著差异 (15～组 :χ2 =7 6 0 ,P <0 0 1;17～组 :χ2 =11 33,P <0 0 1;19～ 2 0岁 :χ2 =15 0 6 ,P <0 0 1) ;左下第一恒磨牙的患龋率最高 ,为 7 2 2 % ,右上第一恒磨牙的患龋率最低 ,为 3 0 6 % ;刷牙与不刷牙之间存在显著差异 (χ2 =2 0 0 4 ,P <0 0 1) ;城区与乡村之间无显著差异 (χ2 =0 0 2 9,P >0 0 5 )。结论 锦州地区中专学生第一恒磨牙的患龋率较高 ,口腔的预防保健及治疗工作任重道远。少吃零食、多参加体育锻炼、保持口腔清洁 ,是预防龋齿的有效措施。
Objective To survey the tooth decay of the first molars among the secondary school students. Methods Through observation with our own eyes,we examined and made a record of 1080 students chosen at random from age 15 to 20. Results As they grew older,the prevalence of the first molars among the boys had no obvious changes while that among the girls was on the rise.The prevalence of the tooth decay of the latter was definitely higher than that of the former,with some distinctions(Age 15～: χ 2=7.60,P<0.01,Age 17～:χ 2=11.33,P<0.01,Age 19～20:χ 2=15.06,P<0.01),the prevalence of the left mandibular first molar was the highest ,7.22%,that of the right maxillary first molars was the lowest,3.06%,there was distinction between those who often brush teeth and those who don't (χ 2=20.04,P<0.01),no distinction between the rural and urban people (χ 2=0.029,P>0.05). Conclusions The prevalence of the tooth decay of the first molars among the secondary school students in Jinzhou is high.Oral health care and the treatment of stomatological diseases still have a long way to go.To eat less snacks ,take more exercise and keep mouths clean are effective measures to prevent tooth decay.
