[Efficacy of prevention of periodontal diseases].

In the present study the results of individual programmes of dental care conducted in a selected population of young adults were shown. The periodontal status was recorded using GPM/T, CPITN, QHI index criteria. In the period of 18 months there was no progression of gingivitis. The severity of gingivitis was clearly reduced, but the percentage distribution was not influenced. The results of the study indicate directions for prevention, diagnosis and therapy. In order to reduce the incidence of the diseases dental care should be concentrated on the motivation and instruction of oral hygiene, plaque control and removal of dental calculus. The findings of the study confirm that a prophylactic programme can prevent more severe gingivitis and marginal periodontitis.
