Recent research trends in tissue regeneration by the biostimulation effect using low-level laser

Nowadays laser gets attention again as a novel method in various treatment fields, such as oral surgery, endodontic and periodontal treatment, etc. Also biostimulation is an special area that we can't pass over. Biostimulation means that low-level laser irradiation promotes the regeneration process in bone, soft tissue, and peri-implant tissue. Although the mechanism has not been elucidated, many reports have supported the biostimulation effect and it is generally accepted. In this feature article, researches up to now were reviewed to know the trends and future research focus.
