Effect of low-level laser therapy during non-surgical periodontal treatments on pocket depth and HbA1c in type 2 diabetic patients

Abstract

Introduction: Periodontal diseases are generally divided into two groups: Gingivitis and periodontitis. Diabetes Mellitus is a group of metabolic diseases that are characterized by increased blood sugar levels (due to defects in insulin production or insulin resistance or both). The aim of this study was to investigate the effect of low-power laser in non-surgical periodontal treatments on pocket depth and HbA1c in type 2 diabetic patients. Methods: Relevant articles were reviewed through searching Embase, PubMed, Google Scholar, Scopus in the 10-years from 2015 to 2021. Cochrane collaboration tool was used to evaluate the quality of articles. Results: From 160 studies, 120 articles were selected after removing duplicate articles and finally 6 studies were reviewed. The test group, which was under diode laser radiation, showed a greater decrease in pocket depth during the three and six-month follow-up. Diode laser irradiation with SRP during 3 and 6 months led to more changes in HbA1C levels. Conclusion: Low level lasers can be used well in non-surgical periodontal treatment in type 2 diabetic patients.
