沈阳地区大学新生牙周状况及口腔卫生习惯调查分析

摘要

Objective: To investigate the periodontal status and the oral hygiene practice in the freshmen of university students in Shenyang. Methods: 497 subjects(205 males and 292 females) were requested to fill a questionnaire for their oral hygiene practice. Periodontal status was evaluated by measuring community periodontal index (CPI) , calculus index (CI) , gingival index (GI) , sulcus bleeding index (SBI) and probing depth (PD). Data were stastistically analysed. Results: The average detection section of calculus in the subjects was 3. 86 ±0. 088, calculus detection rate was 90. 3% of the subjects. The prevalence SBI was 59. 8% . The prevalence of gingivitis was 90.5%. Malocclusion was correlated with the CPI. The earlier the initial brushing, the lower number of segment calculus detected. Conclusion: The freshmen of university students in Shenyang have poor periodontal status. Malocclusion is an important risk factor related to periodontal health.%目的:调查沈阳地区大学新生的牙周健康状况,分析口腔卫生习惯对这一特殊人群牙周健康的影响.方法:按照WHO 1997年制定的口腔健康调查基本方法,对497名大学一年级新生(男205人,女292人)的牙周健康状况进行检查,并采取问卷调查的方式了解其相关的口腔卫生习惯.通过SPSS 11.0统计软件进行Spearman相关性分析和多元线性回归分析.结果:该人群总的牙石检出率为90.3%,牙石检出平均区段为3.86±0.088;牙龈出血检出率为59.8%,牙龈炎患病率为90.5%;CPI指数为1、2、3的人数合计为86.5%.错(牙合)畸形与社区牙周指数(CPI)存在相关性(rs=0.126,P<0.01).初次刷牙时间越早,牙石检出区段数越低(rs=0.091,P<0.05),CPl分值也越低(rs=0.095,P<0.05).结论:沈阳地区大学新生牙周状况较差,牙周疾病的流行以慢性龈炎为主.错(牙合)畸形是影响牙周健康的危险因素.
