Clinical attachment level gain of lasers in scaling and root planing of chronic periodontitis: a network meta-analysis of randomized controlled clinical trials

Lasers in Medical Science volume 35, pages 473–485 (2020)Cite this article

Abstract

The objective of this study was to evaluate the clinical attachment level (CAL) gain of Er:YAG, Er,Cr; YSGG, Nd:YAG; and diode laser (DL) as monotherapy or adjunctive to scaling and root planing (SRP) of chronic periodontitis by network meta-analysis (NMA). Randomized controlled clinical trials (RCTs) about lasers applied in SRP of chronic periodontitis were searched from PubMed, Cochrane Library, Web of Science, Ovid, Science Direct, Wan Fang, and China National Knowledge Infrastructure (CNKI) databases up to September 2018 and from references of selected full-texts and related reviews. Standard mean differences and 95% confidence intervals were counted for CAL gain. The random effects NMA were performed in STATA software. There were 25 RCTs about CAL gain at 3 and/or 6 months after lasers were applied in SRP. No inconsistency was detected. Er:YAG as monotherapy gained significantly more CAL at 3 months than did SRP; no significant differences were detected among other comparisons. In terms of CAL gain at 3 months, the ranking result from best to worst was as follows: Er:YAG as monotherapy, DL adjunctive to SRP, Er:YAG adjunctive to SRP, Er,Cr;YSGG as monotherapy, Nd:YAG adjunctive to SRP, and SRP. In terms of CAL gain at 6 months, the ranking result from best to worst was as follows: DL adjunctive to SRP, Nd:YAG adjunctive to SRP, SRP, Er:YAG adjunctive to SRP, and Er:YAG as monotherapy. Laser-assisted periodontal treatment could be superior to SRP alone and could serve as a good adjunctive treatment tool.
