    Background: The main aim of this cross-sectional study was to investigate the prevalence and severity of erosive tooth wear and its association with dental caries and socio-demographic factors among middle-aged Finnish adults. Methods: Of the total Northern Finland Birth Cohort 1966 (n = 12,058), a convenience sample (n = 3181 adults) was invited for an oral health examination of which 1962 (61.7 %) participated, comprising the final study group. Clinical examinations were carried out by trained and calibrated dentists. Erosive tooth wear was assessed by sextants using the Basic Erosive Wear Examination Index (BEWE, 0-18) and dental caries at surface level using the ICDAS criteria (0-6). Socio-demographic data were obtained from a postal questionnaire. A logistic regression model was generated to test the association of the variables. Results: The prevalence of erosive tooth wear was 75 % and the mean of the BEWE sum score was 3.4 (SD 3.30). Almost half of the members needed non-invasive or invasive measures to prevent further progression of the condition. Of those with erosive lesions, 14.6 % suffered from severe erosive tooth wear. There was a strong positive relationship between the presence of severe erosive tooth wear (BEWE sum score >= 9) and male gender and restorative treatment need. Conclusions: Erosive tooth wear is a common finding in Finnish adult population; almost one in ten suffer from severe erosive tooth wear. Restorative treatment need seems to be associated with severe erosive tooth wear.

    Objective: The aim was to evaluate the association of behavioural and socioeconomic factors with the occurrence of periodontal disease and dental caries, paying special attention to the simultaneous occurrence of these diseases. Materials and methods: The study population consisted of 5255 dentate persons aged >= 30 years from a nationally representative survey. Caries and probing pocket depth were recorded by tooth and calculated in relation to the number of existing teeth. The groups were: non-affected (A), the two most affected quintiles for periodontal disease with little or no dental caries (B), the two most affected quintiles for dental caries with little or no periodontal disease (C) and the two most affected quintiles for both periodontal disease and dental caries (D). Presence of dental plaque was determined, and behavioural and socioeconomic factors were established. Results: Dental plaque, smoking, lack of regular dental check-ups, older age and a basic level of education were strongly associated with the simultaneous occurrence of periodontal disease and dental caries. Conclusions: There are many behavioural and socioeconomic factors that associate with the occurrence of both periodontal disease and dental caries. These factors also increase the risk of individuals having these diseases simultaneously.
