Periodontal pathogens in patients treated with dental implants

Aim: Aim of this study was to compare presence of periodontal pathogens around teeth and implants in patients treated with dental implants using a comercially available PCR test Material and Methods: 25 patients were treated with 50 implants, mean time since implantation 24.5 ± 12.27 months. Bacteria tested were: Aa, Pg, Pi, Tf and Td, clinical indeces were recorded Results: Presence of bacteria around teeth and implants was: 68.8% and 75% for Aa, 82% and 87% for Pg, 31% and 25% for Pi, 88% and 94% for Tf and 87% and 68% for Td. Strong correlation was found between presence of bacteria around teeth and implants (p<0.01). No difference was found in clinical indices between teeth and implants. Very strong correlation was found between time since implant placement and presence of Aa and Td, and weaker corrrelation for Pi and Tf. Conclusion: Similar periodontal pathogens can be found around teeth and implants in patients treated with dental implants, which indicates that periodontal infection needs to be addressed before planning implant therapy, especially in periodontitis susceptible patients.
