Diode Laser as an Adjunctive Treatment for Peri-implant Mucositis: A Systematic Review and Meta-analysis

The early detection and management of peri-implant mucositis may help in reducing inflammatory parameters and arrest disease progression to peri-implantitis. The potential therapeutic benefits of different adjunctive therapies, such as the diode laser, are still not completely understood. The objective of this systematic review and meta-analyses was to assess the outcomes of using diode laser on the management of peri-implant mucositis in terms of changes in periodontal parameters. Electronic databases were searched to identify randomised controlled trials (RCTs) that compared the combined use of mechanical debridement and diode laser with mechanical debridement alone. A specific risk-of-bias tool was used to assess the risk of bias. Data were analysed using a statistical software programme. In total, 149 studies were found. A meta-analysis of 3 RCTs showed no statistically significant differences in probing pocket depths (mean difference [MD], -0.36; 95% confidence interval [CI], -0.88 to 0.16; P = .18) or bleeding on probing (MD, -0.71; 95% CI, 1.58-0.16; P = .11) between the 2 groups at 3 months. In the management of peri-implant mucositis, the combined use of diode laser and mechanical debridement did not provide any additional clinical advantage over mechanical debridement alone. Long-term, well-designed RCTs are still needed.
