Objective: This article aimed to study the effect of LED Phototherapy (LED-PHT) (?630?nm or ?850?nm) on mast cells on the dorsum of the tongue of rodents.
Background Data: Vasodilatation is one of the reported effects of laser light on tissues. Laser light is able to induce the release of mediators responsible for vasodilatation, such as those produced by mast cells.
Purpose: This study aimed to evaluate, histologically, the effect of low-level laser therapy (LLLT) (λ660 nm) on DMBA chemically induced lesions of the oral mucosa of hamsters.
Background Data: Squamous cell carcinoma (SCC) is the most common neoplasm of the oral cavity. It is aggressive, highly proliferative, invasive, and metastatic.
