Efficacy of local antibiotic therapy in the treatment of per
The aim of this systematic review and meta-analysis was to state the efficacy of local administration of antibiotics in the treatment of peri-implantitis in terms of peri-implant probing depth (PPD) and bleeding on probing (BoP) reduction.

Electronic and manual literature searches were conducted. The screening process was done using the National Library of Medicine (MEDLINE by PubMed), Embase, and the Cochrane Oral Health. Twelve studies (365 patients and 463 implants) were included in the systematic review. After peri-implantitis treatment with local antibiotics, PPD was reduced by 1.40 mm (95% confidence interval: 0.82-1.98). When local antibiotics were applied, a 0.30 mm higher reduction of PPD was obtained than in the control group (95% confidence interval: 0.07-0.53). BoP attained an odds ratio value of 1.82 (95% confidence interval: 1.09-3.04), indicating that the likelihood of bleeding is almost two-fold when antibiotics are not locally administrated. Adverse effects were not found after applying local antibiotics.

The local antibiotic administration does reduce, without adverse effects, both peri-implant probing depths and bleeding on probing in patients affected by peri-implantitis, if compared to control groups without local antibiotic application. Patients with dental implants frequently suffer from peri-implantitis. Clinical features of peri-implantitis lesions include the presence of bleeding on probing and increased peri-implant probing depths. Both BoP and PPD have become reduced after the local administration of antibiotics.
