A periodontal survey applying CPITN was carried out in almost 500 male and female factory workers, 35-44 yr of age, in Shanghai, P.R. China. Calculus and shallow pockets were most frequent. Deep pockets of 6 mm and over were seldom found. The mean number of missing teeth was only 2.7 (out of 32). Problems associated with third molars seem to provide the largest immediate oral health problem.
在中国上海,对近500名年龄在35至44岁之间的男女工厂工人进行了一项应用社区牙周指数(CPITN)的牙周调查。牙结石和浅牙周袋最为常见。很少发现6毫米及以上的深牙周袋。平均缺失牙数仅为2.7颗(共32颗牙)。与第三磨牙相关的问题似乎是当前最大的口腔健康问题。
