The oral conditions of 1,993 young adults, 16-30 years old, constituting a statistically representative random sample of the population of Strasbourg, were studied. Plaque, calculus, and gingival indices were determined as well as DMFT and DMFS caries indices. All these indices showed a highly statistically significant linear correlation with age. Sex had a significant influence on caries indices but not on plaque, calculus, or gingival indices. Socioprofessional conditions had a very significant influence on caries and gingival indices but not much on plaque index and not at all on calculus index.
对1993名年龄在16至30岁之间的年轻人的口腔状况进行了研究，这些年轻人构成了斯特拉斯堡人口具有统计学代表性的随机样本。测定了菌斑、牙石和牙龈指数以及DMFT和DMFS龋指数。所有这些指数均显示与年龄存在高度统计学显著的线性相关性。性别对龋指数有显著影响，但对菌斑、牙石或牙龈指数没有影响。社会职业状况对龋和牙龈指数有非常显著的影响，但对菌斑指数影响不大，对牙石指数则毫无影响。
