Effects of low‐level laser therapy on collagen expression and neutrophil infiltrate in 5‐fluorouracil‐induced oral mucositis in hamsters

Abstract

This study supports two mechanisms of action for LLLT in reducing mucositis severity. The increase in collagen organization in response to the 35 mW laser indicates that LLLT promotes wound healing. In addition, LLLT also appears to have an anti-inflammatory effect, as evidenced by the reduction in neutrophil infiltrate.
