The purpose of this study is to compare clinical outcomes (change in bleeding sites (BOP) and probing depth reduction (PPD) after mechanical debridement of implant surfaces at sites exhibiting plaque induced inflammation with or without adjunctive antimicrobial photodynamic therapy (aPDT) and assess the microbiologic profile of plaque samples before and after treatment with or without aPDT samples.
