Low Level Laser Therapy: Its Expanded Tentacles in Dentistry, Review

Background: The introduction of lasers and more specifically Low Level Laser Therapy (LLLT) has been historic in almost every field of dentistry. LLLT nowadays have several applications in many dental fields. The non-invasive treatment of oral diseases is an important aim of modern dentistry. Laser effects have not yet been investigated widely, however as a safer option to traditional therapy they have the ability to become known. Objectives: In this review we aim to highlight the mechanism of action and the effects of LLLT. We also aim to highlight how different wavelengths and energy applied can have a distinct impact on the effectiveness of LLLT. Methodology: The search for articles was carried out on the Google Scholar, PubMed, and Web of Science. The articles selected were the most recent, original ones, and that evaluated the use of LLLT in dentistry. Conclusion: The advantages of this particular laser LLLT are multidirectional, and thus the effects became multifold. Improved knowledge and ongoing work in this direction has culminated in a better awareness of the LLLT's stimulatory, antiinflammatory and biogenerative activity, not just on soft tissue but also on hard tissue. Finally, we provide insight on its current and potential future applications.
