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

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.
