Low-level laser therapy as technique auxiliary in treatment periodontal

Abstract

The purpose of this study is to present a literature review about the use of low-level laser therapy in periodontics emphasizing the new information related in studies that have been made. The main objective is to contribute to clinical use by periodontists. The reviewed articles shows that diode laser therapy helps to decrease the number of microorganisms and bleeding in the periodontal pocket. The biomodulation action generated from this kind of laser accelerates the periodontal tissues repair. Moreover, studies shows that it is possible to obtain an anti-inflammatory and analgesic action induced by the application of low-level laser, respective, because it increase the mast cells and inhibit cyclooxygenase, not converting aracdonic acid in prostaglandin. The laser shows efficiency in the detection of subgingival calculus and in reduction of hypersensitivity dentine that occurs after scaling. It was also observed an increase on the fibroblasts proliferation due to the application of low-level laser, that can bring benefits to regenerative periodontal therapy. So, it possible to conclude that low-level laser can be used in the dental office associated to conventional basic therapy.
