Within a national epidemiological study conducted in France by the 16 Faculties of Dentistry, 946 school-children aged 6 to 15 years were randomly selected and examined in East of France. The Dental Faculty of Strasbourg studied the following departments: Doubs, Jura, Bas-Rhin, Haut-Rhin and Territoire de Belfort. Twenty per cent of the 12 year old children had a DMFT of 0, whereas by the age of 15 this percentage felt to 7%. The mean DMFT and DMFS of the 12 year old children were respectively of 4.6 and 8.7. The mean plaque index varied from 1.2 to 1.5 for all age groups. The mean calculus index increased progressively with age from 0.1 to 0.6. The mean gingival index was almost constant until the age of 8 (0.6 to 0.8). It reached 1.2 at 9 and remained unchanged until 15.
在法国16所牙科学院进行的一项全国性流行病学研究中，946名6至15岁的学童被随机选中并在法国东部接受检查。斯特拉斯堡牙科学院研究了以下地区：杜省、汝拉省、下莱茵省、上莱茵省和贝尔福地区。12岁儿童中有20%的龋失补牙面数（DMFT）为0，而到15岁时，这一比例降至7%。12岁儿童的平均龋失补牙面数（DMFT）和龋失补牙面总和（DMFS）分别为4.6和8.7。所有年龄组的平均菌斑指数在1.2至1.5之间。平均牙石指数随年龄增长从0.1逐渐增加到0.6。平均牙龈指数在8岁之前几乎保持不变（0.6至0.8）。9岁时达到1.2，并一直保持到15岁。
