<i>In vivo</i> clinical and histological thermal effect of a 445 nm diode laser on oral soft tissues during a biopsy

Blue diode laser emits a 445 nm wavelength light, which is extremely effective with hemoglobin, and has an optimal hemostatic effect. This work analyzes its thermal effects clinical efficacy, when used to perform excisional biopsies. Forty-two biopsies were performed the laser; then, extent of perincisional was evaluated patients followed up. Average alteration on epithelial tissue 507.07 µm, connective 320.39 µm. In all cases, it possible obtain histological diagnosis. Diode lasers can be safely biopsies; various intra- postoperative advantages confirmed.
