Abstract

Introduction. Implants can be colonized by microorganisms from oral biofilms and may affect peri-implant tissues health. Among these bacteria, pathogens typically associated with periodontitis can be found, such as Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis, as well as Gram negative enteric bacilli not typically associated with periodontal diseases.
Objective. Superinfecting bacteria were characterized from peri-implant lesions in patients with history of periodontitis.
Materials and methods. Sixty-eight implants were studied in 55 patients; the average patient age was 56 years. Forty-nine implants had peri-implant lesions and 19 were considered stable. Subgingival samples were obtained in affected and stable implants. The samples were streaked on Mac-Conkey agar and incubated at 37°C for 24 hours. The colonies were identified with the kit-BD BBL Crystal E/NF®.
Results. Superinfecting organisms were detected in 20 patients--they were seen more frequently at diseased implants (n=15) than at healthy implants (n=5). The prevalence of superinfecting bacteria on the selected implants was 33.8% (n=23/68). These bacteria were more prevalent among affected implants (n=17 or 25%) than those with stable implants n=6 (8.8%). Klebsiella pneumoniae was the most frequent Gram negative rod detected (n=12).
Conclusions. One-third of the implants had superinfecting organisms. Implants with a peri-implant lesion had a higher frequency of superinfecting bacteria. Klebsiella pneumoniae was the most common superinfecting organism isolated. A multiple infection caused by superinfecting bacteria was present only at diseased implants. These microbial agents potentially affect implant stability.
