Periodontal condition in relation to the adherence to nutrient recommendations in daily smokers

Abstract Aim: To examine whether a healthy diet based on nutrient recommendations is associated with periodontal condition in smokers. Material and Methods: Daily smokers from the cross‐sectional Health 2000 Survey (BRIF 8901) in Finland were analysed in two age groups (30–49 and 50–79 years, n = 704 and 267) and according to the level of oral hygiene. Periodontal condition was measured as the number of sextants with gingival bleeding and teeth with ≥4 mm deepened periodontal pockets. Information on nutrition was collected by a validated food frequency questionnaire and measured using the Baltic Sea Diet Score (BSDS) and the Recommended Finnish Diet Score (RFDS). Results: In the total study population, no association between the scores and periodontal condition was observed. Among 30‐ to 49‐year‐old participants with good oral hygiene, diet scores associated inversely with the number of teeth with deepened periodontal pockets (p = .078 (BSDS) and p = .027 (RFDS)). Conclusions: In a representative sample of Finnish adults who smoke, a healthy diet was not associated with periodontal condition. Among a younger age group with good oral hygiene, a healthy diet associated with better periodontal condition. Age and oral hygiene appeared to modify the association between diet and periodontal condition
