title: Periodontal status in university students.
abstract: The periodontal status of 217 5th-year students (aged 25-26 years and born in Helsinki) at the University of Helsinki was assessed. The students had been eligible for community-based dental care free of charge until the age of 18 years, after which they could obtain low-cost dental care from the Helsinki Student Health Service. Their periodontal status was determined according the community periodontal index of treatment needs; gingival retraction was recorded when 1 mm or more of the cementum was exposed. Code 0 sextant was found for 67% of the women and 57% of the men. 20% of the students examined had sextant scoring of code 3; no-one had code 4 sextants. 69% of the women and 49% of the men had gingival retraction, in average 1.5 +/- 0.5 mm. No correlation was found between the frequency of toothbrushing or the hand used for brushing and the number of retractions, nor did the number of healthy sextants correlate with the frequency of retractions. The findings emphasize the importance of better guidance regarding qualitative aspects of oral hygiene at home.
