All children in Sweden are entitled to regular, free dental care up to 20 years of age. While dental caries generally continues to decline, still there is a pronounced skewness in caries prevalence. Furthermore, the reported increase in dental erosion in young adults is cause for concern.
The aim was to study the prevalence of dental caries and dental erosion in a cohort of Swedish 20 year-olds, with special reference to the influence of previous caries experience and lifestyle as well as parental, socioeconomic and psychosocial factors.
The study was prospective, longitudinal and cross-sectional in design and based on registration of caries lesions, dental erosion, body adiposity status, saliva sampling, interviews, and questionnaires at 20 years of age. Data were available for the same cohort at 1, 3, 6 and 15 years of age. 499 subjects (74 percent of the original cohort) were included. Five individuals were subsequently excluded, leaving a final sample of 494.
74 percent of the subjects had initial and/or manifest caries lesions and/or restorations. The mean number of DimFS was 5.8 and the mean number of DmFS on occlusal surfaces of molars was 1.1. There was a strong relationship between caries activity at 3 and 6 years of age and approximal caries prevalence in premolars and molars at 20 years of age. Overweight/obese individuals had significantly higher caries prevalence than normal weight individuals. Parental, socioeconomic and psychosocial factors during infancy were related to approximal caries at age 20. Dental erosion was found in 75 percent of the individuals: 18 percent of these had extensive erosion. There was a significant association between caries and dental erosion. A relationship was found between dental erosion and lifestyle factors and overweight/obesity.
There is a strong relationship between caries prevalence at age 20 and caries experience in early childhood. Young adults show a high prevalence of dental erosion, but the severity is generally low. Overweight and obese individuals have more caries than normal weight individuals. Parental influence during the formative years has an impact on caries prevalence in young adulthood. In this cohort, dental caries and dental erosion at age 20 are related to overweight/obesity and lifestyle factors.
瑞典所有儿童直至20岁都有权享受定期的免费牙科护理。虽然龋齿总体上持续减少，但龋齿患病率仍存在明显的偏态分布。此外，年轻成年人中牙齿侵蚀的报告增加令人担忧。
本研究旨在调查一组20岁瑞典人的龋齿和牙齿侵蚀患病率，特别关注既往龋齿经历、生活方式以及父母、社会经济和心理社会因素的影响。
本研究采用前瞻性、纵向和横断面设计，基于20岁时龋齿病变、牙齿侵蚀、身体肥胖状况、唾液采样、访谈和问卷调查的记录。该队列在1岁、3岁、6岁和15岁时也有相关数据。纳入了499名受试者（占原队列的74%）。随后排除了5名个体，最终样本为494名。
74%的受试者有初始和/或明显的龋齿病变和/或修复体。DimFS的平均数为5.8，磨牙咬合面的DmFS平均数为1.1。3岁和6岁时的龋齿活动与20岁时前磨牙和磨牙邻面龋齿患病率之间存在密切关系。超重/肥胖个体的龋齿患病率显著高于正常体重个体。婴儿期的父母、社会经济和心理社会因素与20岁时的邻面龋齿有关。75%的个体发现有牙齿侵蚀：其中18%有广泛侵蚀。龋齿与牙齿侵蚀之间存在显著关联。发现牙齿侵蚀与生活方式因素和超重/肥胖之间存在关系。
20岁时的龋齿患病率与儿童早期的龋齿经历之间存在密切关系。年轻成年人牙齿侵蚀患病率较高，但严重程度一般较低。超重和肥胖个体比正常体重个体有更多龋齿。成长阶段父母的影响对年轻成年人的龋齿患病率有影响。在这个队列中，20岁时的龋齿和牙齿侵蚀与超重/肥胖及生活方式因素有关。
