Comparison of two full‐mouth approaches in the treatment of peri‐implant mucositis: a pilot study

Objectives: The aim of the present study was to test the hypothesis that an additional full‐mouth disinfection results in a greater clinical and microbiological improvement compared with sole mechanical debridement within one session in patients with peri‐implant mucositis and treated chronic periodontitis. Material and methods: The study included 13 partially edentulous patients (mean age 51.5 years) with treated chronic periodontitis and 36 dental implants with mucositis (bleeding on probing and/or a gingival index ≥1 at least at one site at baseline, absence of peri‐implant bone loss during the last 2 years before baseline). After randomized assignment to a test and a control group, patients received a one‐stage full‐mouth scaling with or without chlorhexidine. Clinical and microbiological examination was performed at baseline, after 1, 2, 4 and 8 months. Additional microbial samples were taken 24 h after treatment. Microbiological analysis was performed by real‐time polymerase chain reaction. Results: Both treatment modalities resulted in significant reductions of probing depth at implant sites after 8 months, with no significant group differences. The bacteria at implants and teeth could be reduced in every group 24 h after treatment; however, this reduction was not significant after 8 months. Conclusions: Both treatment modalities led to an improvement of the clinical parameters and a temporary reduction of the microflora at implants with mucositis, but without significant inter‐group differences after 8 months.
