Evaluation of the Topical Effect of Probiotic Mouthwash in the Treatment of Patients with Peri-Implant Mucositis.

Peri-implant mucositis is a reversible inflammatory process of the soft tissue surrounding a dental implant. If left untreated, peri-implant mucositis can evolve into peri-implantitis, which leads to the loss of the supporting bone around the implant. The treatment of peri-implantitis is of special importance, since peri-implantitis can be very expensive and troublesome for both the patient and the dentist and a lack of complete resolution can lead to a low probability of implant success. This study aims to evaluate the effects of probiotic tablets on the condition of patients with peri-implant mucositis after scaling. In this double-blind randomized intervention trial, packages containing 14 probiotic capsules or a single-dose placebo were provided to 25 volunteer patients after scaling among those called to a private clinic in Mashhad. During the research process, we used the probing depth (PD) index and the bleeding on probing (BOP) index to diagnose peri-implant mucositis before and after the 28-day period. According to the study findings, on the day of scaling and 4 weeks after scaling and mouthwash use, there was a statistically significant difference in BOP index values between the probiotic group and the placebo group (P < 0.001). There was no difference in PD index values between these two groups. In conclusion, probiotic treatment can be used in interventions, prevention, and dentists' recommendations to alleviate or eradicate peri-implant mucositis.
