Abstract
The composition of oral cavity fl ora is very complex. The purpose of this study was to analyze the clinical periodontal parameters and the composition of the subgingival microfl ora in patients with implant-supported restorations. 28 randomly selected patients were included in the study, mean age 46.7; they had no medical record of periodontal diseases and were not periodontally controlled since the placement of the implants. Mean plaque index was 1.04 ± 0.84, probing depth 2.59 ± 1.13 and gingival bleeding index 1.50 ± 0.84. By method of paper-point sampling of subgingival microfl ora, Actinobacillus actinomycet emcomitans, and four other conditionally pathogenic anaerobic bacteria - Fusobacterium nucleatum, Prevotella intermedia, Prevotella oralis and Campylobacter rectus in 57% patients were found. These results indicate that the fi ndings of plaque and colonization of potentially pathogenic bacteria in 57% of the patients might cause periimplantitis and might lower the success rate of the biological durability of implant-supported restorations, indicating the need for professional control of the subjects.
