title: Dental caries in a group of 15 to 16-year-olds from Göteborg. Part I.
abstract: 301 adolescents aged 15 to 16 years (158 girls and 143 boys) were examined for caries under standardized conditions during the fall and spring terms of 1987/88. Clinical examinations, performed by two calibrated examiners were supplemented with posterior bite-wing radiographs which were assessed by one of the examiners. The mean DFT and DFS scores (incipient lesions included) were 9.8 and 19.4, respectively. The mean DFS score (dentin lesions+restorations) was 6.4. On average 1.9 surfaces had frank cavities or recurrent lesions and 13 surfaces had incipient lesions. Occlusal surfaces contributed 75%, approximal 21% and bucco-linqual 4% to the manifest component of the DFS score (4.8, 1.4 and 0.2 surfaces, respectively). 3% of the incipient lesions were found occlusally, 51% approximally and 46% bucco-linqually (0.4, 6.6 and 5.9 surfaces, respectively). Only 3% of the participants were completely free from caries, whereas 9% had no dentin lesions or restorations. 15% of the subjects with the highest caries prevalence averaged 15.8 dentin lesions or restorations. A tendency towards polarization of low and high caries prevalence groups was observed. Totally 91% of the individuals had occlusal caries, 82% approximal and 76% bucco-lingual, whereas dentin lesions or restorations had 88%, 42% and 14%, respectively.
