目的:调查了解驻川西高原某部新兵社区牙周指数变化情况,为防治牙周疾病提供参考依据。方法:选择驻川西高原某部新兵254例,采用世界卫生组织1997年制定的口腔健康调查基本方法,分别在进驻高原时和驻高原1年后,调查新兵的牙周健康状况,以社区牙周指数(CPI)作为牙周健康观察指标。结果:本组254例,共调查口腔区段1524个。驻高原1年后,新兵早期牙周病和晚期牙周病CPI阳性率均显著或非常显著高于进驻高原时(P<0.05,P<0.01);牙周健康、牙龈炎、牙石CPI阳性率,与进驻高原时比较,差异不显著(P>0.05)。其中,口腔43~33区段牙周健康CPI阳性率非常显著低于进驻高原时(P<0.01),早期牙周病和晚期牙周病CPI阳性率显著或非常显著高于进驻高原时(P<0.05,P<0.01);其余区段牙周健康、牙龈炎、牙石、早期牙周病及晚期牙周病CPI阳性率,与进驻高原时比较,均差异不显著(P>0.05)。结论:驻川西高原某部新兵1年间牙周疾病CPI阳性率有所升高,其中下前牙区段CPI变化显著,应加强牙周疾病防治。
Objective: To investigate the changes of periodontal index of some recruits in western Sichuan Plateau to provide reference for prevention and treatment of periodontal disease. Methods: A total of 254 recruits from the western Sichuan Plateau were recruited. Using the basic method of oral health survey established by the World Health Organization in 1997, the periodontal health status of recruit was investigated respectively one year after entering the plateau and the plateau. Index (CPI) as a periodontal health indicators. Results: The group of 254 cases, a total of 1524 oral investigation of the mouth. The positive rate of CPI in periodontal disease and periodontal disease in recruits was significantly or very significantly higher than that in stationed plateau (P <0.05, P <0.01) after one year in plateau. The positive rate of periodontal health, gingivitis and calculus CPI , Compared with the stationed in the plateau, the difference was not significant (P> 0.05). The positive rate of periodontal CPI was significantly lower in the period from 43 to 33 (P <0.01), and the positive rate of CPI in early periodontal disease and late periodontal disease was significantly or significantly higher than that in the stationed plateau <0.05, P <0.01). The positive rates of CPI in periodontal health, gingivitis, calculus, early periodontal disease and periodontal disease in the remaining sections were not significantly different from those in the period of entering the plateau (P> 0.05). Conclusion: The CPI positive rate of periodontal disease in one recruits in western Sichuan Plateau increased in one year. The CPI in lower anterior segment changed significantly, and the prevention and treatment of periodontal disease should be strengthened.
