The Efficacy of Implant Surface Decontamination Using Chemicals during Surgical Treatment of Peri‐implantitis: A Systematic Review and Meta‐Analysis

AlexandrosSfakianakis shared this article with you from Inoreader The Efficacy of Implant Surface Decontamination Using Chemicals during Surgical Treatment of Peri‐implantitis: A Systematic Review and Meta‐Analysis via Journal of Clinical Periodontology ABSTRACT Aim To answer the following PICOS question: in adult patients with peri-implantitis, what is the efficacy of surgical therapy with chemical surface decontamination of implant surfaces in comparison with surgical therapy alone or surgery with placebo decontamination, on probing pocket depth (PD) reduction and bleeding on probing (BoP)/suppuration on probing (SoP), in randomized controlled clinical trials (RCTs) and non-RCTs with at least 6 months of follow-up? Materials and Methods Six databases were searched from their inception up to May 20, 2022. Data on clinical outcome variables were pooled and analyzed using mean differences (MDs), Risk Ratios (RR) or Risk Differences (RD) as appropriate, 95% confidence intervals (CI), and prediction intervals (PIs) in the case of significant heterogeneity. Primary outcomes were determined as changes in PD and BoP/SoP. Secondary outcomes were detrmined as radiographic marginal bone loss (MBL), implant loss, and disease resolution. PROSPERO registration number: CRD42022325603. Results Six RCTs - two moderate, three high, and one low risk of bias (RoB) studies - were included. These studies test the adjunctive effect of photodynamic therapy (PDT), chlorhexidine (CHX), and administration of local antibiotics (LAbs) during surgery on the clinical outcome. In a single 12-month study, the adjunctive use of local antibiotics showed a clinically relevant reduction of PD )MD= 1.44; 95% CI [0.40; -2.48] and MBL (MD= 1.21; 95% CI [0.44; 1.98]; one trial, 32 participant). PDT showed a small but significant reduction in BoP (MD= 7.41%; 95% CI [0.81; 14.00]; P=0.028; two trials; 42 participants). Treatment with CHX resulted in no significant changes in PD, BoP, or MBL compared to placebo saline solution. None of the interventions affected disease resolution and implant loss. Certainty of the evidence was very low for all outcome measures assessed. Conclusions Within the limitations of this systematic review and the meta-analysis, adjunctive use of chemicals such as PDT, CHX, LAbs for surface decontamination during surgery of peri-implantitis cannot be recommended as superior to standard debridement procedures (mechanical debridement +/- saline).
