Systematic review of the adjunctive use of diode and Nd:YAG lasers for nonsurgical periodontal instrumentation.
OBJECTIVE
The aims of this study were (1) to conduct a literature search and systematically evaluate the additional therapeutic effects of pulsed Nd:YAG or diode laser use in patients with periodontitis, (2) to assess evidence supporting the additional benefit of laser-mediated periodontal treatment in conjunction with scaling and root planning (SRP) (not as monotherapy), and (3) to interpret the evidence presented in retrieved publications.


BACKGROUND
Opinions about the additional use of diode lasers in the nonsurgical treatment of plaque-induced periodontal lesions are conflicting. The April 2011 American Academy of Periodontology's "Statement on the Efficacy of Lasers in the Non-Surgical Treatment of Inflammatory Periodontal Disease" asserted that the use of a laser as monotherapy or in addition to nonsurgical periodontal instrumentation conveyed no advantage.


METHODS
After initial screening, 23/77 potentially relevant articles and abstracts identified through electronic and manual searches of the MEDLINE(®)/PubMed database and the Cochrane Central Register of Controlled Trials (1990-2012) were included in this review.


RESULTS
A meta-analysis could be performed. The results indicate that Nd:YAG or diode laser, used in an adjunctive capacity to SRP, may provide some additional benefit, in 6 month studies, compared with mechanical debridement.


CONCLUSIONS
The results show the adjunctive benefits that diode laser treatment can provide when it is used as an adjunct to nonsurgical periodontal treatment in adults with chronic periodontitis. Further long-term, well-designed, parallel randomized clinical trials are needed to assess the effectiveness of the adjunctive use of the diode laser, as well as the appropriate dosimetry and laser settings.
