Abstract

To investigate whether the adjunctive use of diode laser provides additional benefits to scaling root planning alone in patients with chronic periodontitis, a meta-analysis was conducted according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement and the Cochrane Collaboration. A literature search was performed on seven databases, followed by a manual search. Weighted mean differences and 95 % confidence intervals were calculated for the clinical attachment level, probing depth, and changes in the plaque and gingival indices. The I (2) test was used for interstudy heterogeneity. Visual asymmetry inspection of the funnel plot, Egger's regression test, and the trim-and-fill method were used to investigate publication bias. All outcomes were evaluated at 6 months. No significant differences were observed for any investigated outcome of interest. No evidence of heterogeneity or publication bias was detected. These findings suggested that the use of diode laser as an adjunctive therapy to conventional nonsurgical periodontal therapy did not provide additional clinical benefit. However, given that few studies were included in the analysis, and that three of the five included studies had a high risk of bias, the results should be interpreted with caution. Important issues that remain to be clarified include the influence of smoking on clinical outcomes, the effectiveness of adjunctive diode laser on microbiological outcomes, and the occurrence of adverse events. Future long-term well-designed parallel randomized clinical trials are required to assess the effectiveness of the adjunctive use of diode laser, as well as the appropriate dosimetry and laser settings.
