title: Periodontal conditions in a Swedish city population of adolescents: a cross-sectional study.
abstract: The aim of this epidemiological survey was to analyze the periodontal conditions of 19-year old individuals in an urban area of Sweden, with special reference to gender and socioeconomic factors. A randomized sample of 272 individuals living in Göteborg, Sweden, was clinically examined with regard to oral hygiene, gingivitis, periodontal pockets, probing attachment loss (PAL) and gingival recession. Bitewing radiographs were used for assessments of alveolar bone level (ABL) and dental calculus. A questionnaire-based interview regarding oral hygiene habits was included. Data were analyzed with regard to differences between gender and socioeconomic grouping. The subjects showed a mean plaque score of 59% and a gingivitis score of 44%. 70% of the adolescents had a plaque score of > or = 50%, whereas corresponding figure for gingivitis was 37%. 27% of the subjects had at least one tooth with gingival recession. The mean prevalence of sites with probing depth of > or = 6 mm was 0.5, and the prevalence of PAL > or = 2 mm was 0.7. A radiographic bone level of > or = 2 mm was observed at on average 0.8 teeth per subject. Females had significantly less plaque and gingivitis than males and significantly higher number of teeth with gingival recession. There were no clinically significant differences in periodontal conditions between socioeconomic groups. In conclusion,the survey revealed higher prevalence of plaque and gingivitis among male than female adolescents but no differences between socioeconomic groups.
