Retrospective study on the efficiency of the diode laser in the non-surgical treatment of paradontopathy

Abstract

Some studies have demonstrated that DL as an adjunct of SRP led to an improvement in some clinical parameters. Nevertheless, regarding gingival inflammation clinical parameters, some studies did not find positive results. Unlike SRP, conflicting results have been found in numerous clinical trials that evaluated the clinical efficacy of DL. Notably many studies that found significant differences in support of laser cohorts, there were questions regarding whether the results were clinically relevant, thus it was concluded that DL did not improve conventional treatment,especially regarding with long term results. The goal of this review is to evaluate the efficacy of using LD at 800-980 nm as an adjunct to non-surgical periodontal therapy in the treatment of periodontitis. In this review, only studies concerning the LD at 800-980 nm were included. From the methodological point of view, this study was carried out as a review of the literature in its methods of research, analysis and synthesis. The field was narrowed to select only randomized controlled clinical trials (RCTs) conducted from 2010 to 2020. In total there were 84 articles, eight of which were included in the review because they met the inclusion criteria. The clinical, microbiological and immunological parameters of the studies were compared. In four of the eight studies, the greatest benefits, in terms of clinical parameters, were obtained in patients treated with diode laser plus root planning and scaling (SRP) compared to the control group. The best results in favor of the use of the diode laser, in terms of immunological parameters, were found after 30 days.
