To evaluate the progression of dental erosion in 13-14 year-olds after 4 years, and its association with lifestyle and oral health.
227 randomly selected 13-14 year-olds from a Public Dental Clinic, Örebro, Sweden, were investigated. A clinical examination was performed which included dental caries/gingival/plaque status, as well as grading of dental erosion at the tooth surface and participant levels in "marker teeth", including buccal/palatal surfaces of 6 maxillary anterior teeth (13-23), and occlusal surfaces of first molars. An interview and a questionnaire regarding drinking habits and other lifestyle factors were completed. All investigations were repeated at follow-up. The participants were divided into high and low progression erosion groups and logistic regression statistics were applied.
175 individuals participated at follow-up. Progression occurred in 35% of the 2566 tooth surfaces. 32% of the surfaces had deteriorated by one severity grade (n=51 individuals) and 3% by two grades (n=2 individuals). Boys showed more severe erosion than girls at the follow-up. Among the variables predicting greater progression, a lower severity of erosive wear at baseline had the highest OR (13.3), followed in descending order by a "retaining" drinking technique, more frequent intake of drinks between meals, low GBI and lesser sour milk intake, with reference to the baseline recording. Using these five variables, sensitivity and specificity were 87% and 67% respectively, for predicting progression of erosion.
Progression of erosive lesions in Swedish adolescents aged 13-14 years followed up to age 17-18 years was common and related to certain lifestyle factors.
In permanent teeth, dental erosion may develop early in life and its progression is common. Dental health workers should be made aware of this fact and regular screenings for erosion and recording of associated lifestyle factors should be performed.
评估13 - 14岁青少年4年后牙齿侵蚀的进展情况及其与生活方式和口腔健康的关联。
对从瑞典厄勒布鲁市一家公共牙科诊所随机选取的227名13 - 14岁青少年进行调查。进行了临床检查，包括龋齿/牙龈/牙菌斑状况，以及对“标记牙”牙齿表面和参与者层面的牙齿侵蚀程度分级，“标记牙”包括6颗上颌前牙（13 - 23）的颊面/腭面以及第一磨牙的咬合面。完成了关于饮酒习惯和其他生活方式因素的访谈及问卷调查。所有调查在随访时重复进行。将参与者分为侵蚀进展高分组和低分组，并应用逻辑回归统计分析。
175名个体参与了随访。在2566个牙齿表面中，35%出现了进展。32%的表面恶化了一个严重程度等级（n = 51人），3%恶化了两个等级（n = 2人）。随访时男孩的侵蚀比女孩更严重。在预测进展程度更高的变量中，基线时侵蚀性磨损严重程度较低的OR值最高（13.3），其次依次为“保留式”饮酒方式、餐间更频繁饮用饮料、低牙龈出血指数（GBI）以及较少摄入酸牛奶，以基线记录为参照。使用这五个变量，预测侵蚀进展的敏感性和特异性分别为87%和67%。
对13 - 14岁瑞典青少年随访至17 - 18岁，侵蚀性病变进展情况常见且与某些生活方式因素相关。
在恒牙中，牙齿侵蚀可能在生命早期就出现且进展情况常见。牙科保健人员应了解这一事实，并应定期进行侵蚀筛查及记录相关生活方式因素。
