Biological implant failures are primarily related to biofilm, which can lead to peri-mucositis and, further on, peri-implantitis. The 810-nm diode laser has an affinity for pigmented chromophores, so its use in the peri-implant sulcus has a significant bactericidal effect on the black-pigmented anaerobes such as Porphyromonas gingivalis. Therefore, it can be used to eliminate or reduce the bacterial count in the peri-implant sulcular fluid (PISF), thus increasing the life of the implants and reducing the chances of failure. The purpose of this study was to evaluate the efficacy of the 810-nm diode laser for the maintenance of dental implants and its use as a regular in-office tool for limiting the microbiological count in the PISF. Twenty patients undergoing implant treatment at the Department of Periodontology and Oral Implantology were randomly selected for the study. PISF samples were collected before and after the sulcus was lased with an 810-nm diode laser and sent for quantitative microbiological analysis using universal bacterial count, and the quantity of P gingivalis was evaluated using real-time polymerase chain reaction (PCR). The analysis revealed that after diode application, the median percentage drop in the microbial count was 76.67% and the median percentage drop in P gingivalis count was 99.28%. The use of an 810-nm diode laser resulted in the following outcomes: (1) drastic reduction in the total bacterial count around the implant and (2) significant reduction in the P gingivalis count, as evaluated by real-time PCR.
