[Localized periodontal recession--only caused by the chronic brushing trauma?].

Localized periodontal recession (LPR) is not rarely found in adults: 10.4% in subjects age 16-19 years, 24.8% in 20-24-year-old persons, and 46.8% in the age group of 35-44 years (N = 11,401 subjects). There is an accumulation of LPR-patients, who referred to the Department of Periodontology, in young adults. Patients suffering from LPR show, in comparison to healthy people, a smaller diameter of the canine's apical basis both in the maxillary and mandibular arches, a smaller circumference of the alveolar crest as well as an upper canine-crown which is turned out from the teeth arcus in a more labial direction. The vestibular sites of teeth 44, 23, 34, 13, 14, 24, and 43 are mainly affected by LPR. Right-handers generally show more and stronger LPR in both arches as well as a smaller value of oral hygiene index. The chronic trauma of teeth brushing is very important in the pathogenesis of the LPR. Prevention of LPR involves individual oral health education to protect the vestibular gingiva from chronic brushing trauma.
