Difference of Two Antiseptic Gels for the Treatment of Peri-Implant Mucositis on Plaque Index and Bleeding Score: A Randomized Controlled Clinical Study

Aim: To analyze and compare the effectiveness of two antibacterial gels in the treatment of mucositis. Methods: After signing the informed consent, in accordance with the Helsinki Declaration of 1975, revised in 2000, 21 patients were included in the study and divided by randomization into two groups. At the baseline, the modified bleeding index (mBI) and plaque index (PI) values were measured, and an oral hygiene and implant disinfection session was carried out. The session was repeated at 7, 15, and 30 days and after 2 and 3 months from the baseline. Two products were used—a bioadhesive gel in the test group and a 1% chlorhexidine gel in the control group. Results: Due to three dropouts, the final sample was composed of 18 patients. An improvement in periodontal indices was observed, similar to mBI and PI values, in both groups. There were no complications except for the appearance of pigmentations in the control group. Conclusions: The antibacterial power and effectiveness of the two gels are comparable. Considering the small sample size of the study cohort, further studies are needed to validate the results obtained from this pilot study.
