Cold lasers for photobiomodulation in pulpotomy of primary molars: A short review

Abstract

Photobiomodulation with diode lasers of 660 and 810 - 980 nm is used for the proliferation of fibroblasts and to enhance the healing of oral lesions or surgical wounds. It has the potential to stimulate the formation of reparative dentin and preserve pulp vitality. Photobiomodulation uses low-level laser therapy (LLLT) which works on the principle of supplying direct bio-stimulative light energy to the cells. Based on these characteristics, numerous studies are conducted on photobiomodulation with a diode laser for pulpotomy in primary molars. This review article aims to provide data to clinicians regarding varying parameters used for photobiomodulation in pulpotomy and their clinical outcomes in primary molars.
