Adjunctive effect of mouthrinse on treatment of peri-implant mucositis using mechanical debridement: A randomized clinical trial.

ABSTRACT

AIM: To study effect of delmopinol hydrochloride (DEL) in comparison with chlorhexidine digluconate (CHX) and a placebo (PLA) in addition to non-surgical mechanical debridement in patients with peri-implant mucositis. MATERIALS AND METHODS: Eighty-nine patients with at least one implant diagnosed with peri-implant mucositis were randomly assigned to one of three study groups (DEL, CHX and PLA). Professional non-surgical mechanical debridement was performed at baseline. Mouth rinsing was carried out by the patients twice a day in addition to their regular oral hygiene practices. Assessments of efficacy were performed for the primary outcome - Implant bleeding on probing (IBOP%) and secondary outcomes - modified Bleeding Index (mBI) and modified Plaque Index (mPI) at 1 and 3 months. RESULTS: At 3 months, there was statistically significant reduction in IBOP% and mBI within the study groups compared to baseline. However, there was no statistically significant difference between the study groups at 3 months follow-up. Moreover, there was a statistically significant difference according to mPI at 1 month between the chlorhexidine and placebo group (p = .004). CONCLUSIONS: This study confirms that mechanical debridement combined with oral hygiene instruction is effective in treatment of peri-implant mucositis. The clinical effects between groups were comparable.
