title: Risk indicators for dental erosive wear among 18-yr-old subjects in Oslo, Norway.
abstract: The aim was to investigate risk indicators associated with dental erosive wear among 18-yr-old subjects in Oslo, Norway. Of 3,206 adolescents invited to participate in a screening examination for erosive wear, 1,456 were examined (giving a response rate of 45%). As part of the examination all participants completed a self-administered questionnaire. Associations between the presence of erosive lesions and the possible risk indicators were assessed by logistic regression analyses, taking into account the hierarchical relationships between the independent variables. Of all 18-yr-old subjects examined, 38% had at least one tooth with erosive lesions. Multivariate analyses showed significant associations between the presence of erosive wear and being male, brushing teeth once per day or less, episodes of vomiting, daily/weekly episodes of gastro-oesophageal reflux, consumption of fruit juice and sugary soft drinks several times per day, as well as consumption of sugary soft drinks daily to once per week. In conclusion, in addition to gender, dietary habits such as frequent consumption of fruit juice and sugary soft drinks, and the occurrence of reflux and vomiting, appear to be risk indicators for erosive wear. When counselling adolescents at risk, the gender-specific risk indicators should be taken into account.
