Résumé
There is no reliable treatment procedure for peri-implant disease, despite the rise in its incidence. This study sought to evaluate the short-term safety and efficacy of antimicrobial photodynamic therapy (a-PDT) on peri-implantitis by assessing the volume of pus discharge after a-PDT. Patients with pus discharge from a peri-implant pocket were recruited from December 1st, 2019 to April 30th, 2020. The enrolled implants were randomly assigned to one of two groups, the irrigation and a-PDT groups. Their peri-implant pocket was irrigated with normal saline in the irrigation group, and a saline irrigation and subsequent a-PDT with toluidine blue (TB) was performed in the a-PDT group. The safety and efficacy of a-PDT were assessed 7 days after treatment. Twenty-five implants in 21 patients (irrigation group; 13 implants, a-PDT group; 12 implants) were registered. No complication was observed after a-PDT. Pus discharge was decreased in 7 of 12 implants (58.3 %) in the a-PDT group, and in 2 of 13 implants (15.4 %) in the irrigation group. According to Fisher's exact test, a-PDT resulted in a statistically significant decrease in pus discharge compared to irrigation alone (p = 0.0414). a-PDT was confirmed to be a safe treatment for peri-implantitis, and the short-term efficacy of a-PDT with TB on peri-implantitis was clarified. Nevertheless, its efficacy remains restricted, and a new combination therapy of a-PDT and decontamination procedures is expected to be developed in future.

BACKGROUND
BACKGROUND
There is no reliable treatment procedure for peri-implant disease, despite the rise in its incidence. This study sought to evaluate the short-term safety and efficacy of antimicrobial photodynamic therapy (a-PDT) on peri-implantitis by assessing the volume of pus discharge after a-PDT.
METHODS
METHODS
Patients with pus discharge from a peri-implant pocket were recruited from December 1st, 2019 to April 30th, 2020. The enrolled implants were randomly assigned to one of two groups, the irrigation and a-PDT groups. Their peri-implant pocket was irrigated with normal saline in the irrigation group, and a saline irrigation and subsequent a-PDT with toluidine blue (TB) was performed in the a-PDT group. The safety and efficacy of a-PDT were assessed 7 days after treatment.
RESULTS
RESULTS
Twenty-five implants in 21 patients (irrigation group; 13 implants, a-PDT group; 12 implants) were registered. No complication was observed after a-PDT. Pus discharge was decreased in 7 of 12 implants (58.3 %) in the a-PDT group, and in 2 of 13 implants (15.4 %) in the irrigation group. According to Fisher's exact test, a-PDT resulted in a statistically significant decrease in pus discharge compared to irrigation alone (p = 0.0414).
CONCLUSIONS
CONCLUSIONS
a-PDT was confirmed to be a safe treatment for peri-implantitis, and the short-term efficacy of a-PDT with TB on peri-implantitis was clarified. Nevertheless, its efficacy remains restricted, and a new combination therapy of a-PDT and decontamination procedures is expected to be developed in future.
