沈阳地区大学新生牙周状况及口腔卫生习惯调查分析

Investigation of periodontal status and oral hygiene practice in the freshmen of university students in Shenyang

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),CPI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。错畸形是影响牙周健康的危险因素。

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.
