Efficacy of mechanical debridement with adjunctive probiotic therapy in the treatment of peri-implant mucositis in cigarette-smokers and never-smokers

Abstract

Background: Efficacy of mechanical debridement (MD) with adjunctive probiotic therapy (PT) in the treatment of peri-implant mucositis (PiM) in cigarette-smoking and never-smoking subjects remains uninvestigated. Purpose: The aim was to assess the efficacy of MD with adjunctive PT in the treatment of PiM in cigarette-smoking and never-smoking individuals. Materials and Methods: Patients with (group I) and without PiM (group II) were included. Demographic data was collected using a questionnaire. Treatment-wise, patients in groups I and II were subdivided into: (a) Patients that underwent MD with adjunct PT (using Lactobacillus reuteri); and (b) MD alone. In all groups, probing depth (PD), plaque index (PI), and bleeding on probing (BOP) were measured at baseline and compared after 3- and 6-months. Baseline peri-implant crestal bone levels were also measured. Sample-size estimation was performed, and statistical comparisons were done using one-way analysis of variance and Bonferroni post-hoc adjustment tests. P values under.05 were deemed significant. Results: Eighty individuals (group I: 40 cigarette-smokers and group II: 40 never-smokers) with PiM participated in this study. At all-time intervals, no significant difference in PD, PI, and BOP were observed in all patients in group I. At 3-months' follow-up, the differences in BOP (P
