title: Oral hygiene in a group of supervised patients with fixed prostheses.
abstract: The oral hygiene, the gingival condition, pocket depth, and the incidence of caries on crowned teeth were studied during a period of 5 years in a group of patients (114) who had been treated with fixed dental prostheses. Prior to the prosthetic treatment, the patients received periodontal treatment. During the study, the subjects participated in an oral hygiene program. Crown margins were located sub-gingivally, at the gingiva and supra-gingivally. When the crown margins were located sub-gingivally, there was an increase in Gingival Index scores 2, and in pocket depth, compared to supra-gingival placement. An improvement of gingival health was recorded where the crown margins were located supra-gingivally. Caries lesions developed on 3.5% of the tooth surfaces which had recieved crowns.
