上海市黄浦区9548名中学生青少年牙周炎的调查

目的：调查了解上海市黄浦区11－19岁中学生青少年牙周炎的患病率，以便早期发现、明确诊断和及时治疗。方法：2000年1月－2001年4月，对9548名学生（男性4739人，女性4809人）进行软垢指数，牙石指数、龈沟出血指数、社区牙周指数检查。结果：牙周炎患病率为0．76％，男：女＝1：1．03（P＞0．05）。随着年龄的增长，牙龈出血及牙行的检出率逐渐上升，牙周炎的患病率也逐渐增高。结论：上海市黄浦区9548名中学生青少年牙周炎患病率为0．76％，由于牙周病新分类的出现，这些病例需进行重新评价，还必须加强口腔卫生的宣教及防治工作。

Juvenile Periodontitis Survey in 9548 Middle School Students at Huangpu District in Shanghai

Objective 9548 middle school students from 11-19 age at Huangpu District in Shanghai were investigated to study the prevalence of juvenile periodontitis(JP). The purpose of the present study was to discover JP at early stage and make correct diagnosis, so the patients can be treated on time.Methods From January 2001 to April 2001, debris index(DI), calculus index(CI), sulcus bleeding index(SBI) and community periodontal index for treatment needs(CPITN) were examined in each student. Results In 9548 investigated (4739 males and 4809 females), prevalence of JP was 0.76%, the ratio of males to females was 1:1.03(P<0.05). With aging, the detectable rate of gingival bleeding and calculus was increasing, the prevalence of JP was also increasing.Conclusion Since the new classification system of periodontal disease was established, the above cases are worth reevaluating.We should also enhance oral hygiene of the young people.
