Oral Health and Risk Factors for Oral Disease

Completed

• Conditions: Periodontal Diseases; Dental Caries; Quality of Life

• Registration Number: NCT04081025
• Lead Sponsor: Dalarna County Council, Sweden

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.

Detailed Description

Traditionally, the number of teeth has been a measure of good oral health, and the World Health Organization (WHO) stipulated goals of a minimum of 20 functional teeth at the age of 80 years have been reached in some industrialized countries. Oral Health means more than good teeth and is integral to general health. The relationship between oral and general health has been recognized. For example, periodontal disease is associated with diabetes and rheumatoid arthritis. The severity of periodontal disease and number of teeth have been associated with an increased burden of cardiovascular disease.

There is a lack of longitudinal studies of oral Health and risk factors for oral disease.

Primary Outcome Measures

Name	Time	Method
Periodontal disease	At one occasion (2018)	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 dental caries	Ten years (2008-2018)	Number of teeth with dental caries
Dental caries	At one occasion (2018)	Number of teeth with dental caries
Risk factors for periodontal disease	Ten years (2008-2018)	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	One occasion (2018)	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
