BACKGROUND/AIM: There are few studies of caries development and caries-related factors from early age to young adulthood. The aim of the present study is to analyse caries prevalence in 20-year-olds in relation to their previous caries experience.
Oral health from 3 to 20 years of age was followed longitudinally in a cohort of 499 individuals. The clinical and radiographic incidence of caries and restorations in 494 20-year-olds was related to caries data at 3, 6 and 15 years of age.
Twenty-six per cent of the 20-year-olds were caries-free. The mean number of initial and manifest lesions and restorations (Di + mFS) was 5.8. Initial lesions comprised 40% of the Di + mFS. Of the occlusal surfaces of molars and premolars, 12 and 4%, respectively, had manifest caries or restorations. Compared with individuals who had been caries-free during childhood (primary dentition) and adolescence, those with a history of caries activity while growing up had statistically significantly more approximal lesions at the age of 20 (DmFSa 0.6 vs. DmFSa 4.6, respectively). Those with manifest caries during childhood but caries-free at 15 years had a low caries prevalence at 20 years of age (DmFSa 1.3). Few new lesions developed after age 15. However, 50% of initial lesions at this age had progressed to manifest lesions at age 20.
There is a relationship between caries prevalence at age 20 and early caries experience.
背景/目的：从幼年到青年期，有关龋齿发展和相关因素的研究较少。本研究的目的是分析 20 岁人群的龋齿患病率与既往龋齿经历的关系。
对 499 名个体进行了为期 3 至 20 年的口腔健康纵向随访。将 494 名 20 岁人群的临床和放射学龋齿发生率和修复情况与 3、6 和 15 岁时的龋齿数据相关联。
26%的 20 岁人群无龋齿。初始和明显病变及修复（Di + mFS）的平均值为 5.8。初始病变占 Di + mFS 的 40%。磨牙和前磨牙的咬合面中，分别有 12%和 4%出现明显龋齿或修复。与儿童期（乳牙期）和青春期无龋齿的个体相比，在成长过程中有龋齿活动史的个体在 20 岁时近中面的病变数量明显更多（DmFSa 0.6 比 DmFSa 4.6）。儿童期有明显龋齿但 15 岁时无龋齿的个体在 20 岁时龋齿患病率较低（DmFSa 1.3）。15 岁后很少有新病变发展。然而，该年龄组的 50%初始病变在 20 岁时已进展为明显病变。
20 岁时的龋齿患病率与早期龋齿经历有关。
