Abstract

AIM: To find out if dental erosion is more frequent nowadays, the objective was to compare the prevalence and severity of dental erosion among 16–18 year-olds in Norway in 2012 with 15 year-olds in 1985. Further, the intention was to investigate the incidence and progression of erosive lesions from age 15 to 21. METHODS: Two calibrated clinicians recorded dental erosion on study models from 1985 (n. 300; 150 girls/ 150 boys), at age 15 (born 1970). To record the incidence and progression of dental erosion, study models of the same individuals were examined at ages 18 (1988, n. 88) and 21 (1991, n. 35). The Visual Erosion Dental Examination (VEDE) system was used to score dental erosion on index surfaces; occlusal surfaces on permanent first molars and labial/ palatal surfaces on maxillary front teeth. CONCLUSION: Thirty years ago, the prevalence of dental erosion was in the same order as reported nowadays, but the condition seemed less severe.
