The aim of this review was to investigate the additional effects of diode laser irradiation in combination with nonsurgical periodontal therapy. An electronic search of publications was established from three electronic databases: Cochrane, PubMed and Web of Science. The search strategy used a combination of controlled vocabulary and free-text words. Inclusion and exclusion criteria were defined by the authors before the start of the study. The inclusion criteria were all studies published in English language, randomized controlled trials, based on human subjects. All trials were designed to evaluate the efficacy of the diode laser therapy as an adjunct to nonsurgical periodontal therapy in the treatment of chronic periodontitis patients. All studies analyzed are not older than five years. The search resulted in 188 titles. After the analysis of the abstracts, an article was excluded because it was not relevant for the study and two because it treated aggressive periodontitis. At the end only 6 articles were included in the qualitative analysis. The potential role in chronic periodontal disease treatment of diode laser is still not demonstrated. Several studies regard the diode laser therapy, but there is still heterogeneity for what it concerns research and clinical protocols. As a result, several randomized controlled trials are needed to obtain certain data.
Keywords: chronic periodontitis; diode laser; laser therapy; periodontal disease.
