Brief Summary
Oral health has improved considerably in recent decades in Sweden, as well as in other countries. However, despite great improvements with regard to periodontal disease and dental caries in recent decades, global problems still persist, and as a consequence of retaining natural teeth high up in age, the risk for oral disease increases.

Outcome Measures
Primary Outcomes (7)
Periodontal disease
The severity of alveolar bone loss are based on bone levels at interproximal sites as seen on radiographs in the premolar and molar regions in both jaws. The diagnostic categories are (1)'no bone loss', defined as normal alveolar bone height in the molar and premolar regions (i.e., a distance ≤2 mm between the cemento-enamel junction and the alveolar bone crest (2) moderate bone loss, defined as alveolar bone loss \>2 mm but not exceeding one-third of the length of the roots, or if angular bony defects/furcation defects degree II and III are present on two to three teeth in the molar-premolar region; and (3)'severe bone loss', defined as alveolar bone loss exceeding one-third of the length of the roots, or if angular bony defects/furcation defects degree II and III are present on more than three teeth in the molar and premolar regions.

Risk factors for periodontal disease
A questionnaire is used to assess risk factors for periodontal disease.The outcome variables is: Education: * Up to secondary school * University or college of higher learning Economy for dental care: * No limited financial resources for dental care * Limited financial resources for dental care Marital status: * Married/cohabitant * Single living Tobacco use: * Current smoker * Former smoker

Oral Health Related Quality of Life
A 9-item survey instrument (Oral Impact on Daily Performance), using a five-point Likert scale, ranging from "never" (1), "less than once a month (2), 1-2 times a month (3), 1-2 times a week (4), and "every, or nearly every day" (5) was used. The questions are as follows: "during the past 6 months, how often have problems with your mouth or teeth caused any difficulty with: * Eating and enjoying food * Speaking * Pronouncing clearly * Doing light physical activities * Cleaning teeth * Sleeping and relaxing * Smiling, laughing and showing teeth without embarrassment * Maintaining usual emotional state without being irritable * Carrying out major work or social role and enjoying contact with people
