Objectives: To evaluate the thermal changes and histologic alterations produced in ex vivo and in vivo specimens of oral mucosa by the quantum molecular resonance (QMR) scalpel. Materials and methods: Using electronic probes positioned within the mandibles of pigs, we measured temperature changes induced in the mucosa during incisions made with (1) a conventional cold blade; (2) a QMR blade; (3) a Nd:YAG laser (1064 nm); (4) an Er:YAG laser (2940 nm). We also evaluated the epithelial, connective, and vascular tissue modifications in 49 biopsy specimens of benign fibrous oral lesions collected with these same surgical instruments. Results: The QMR blade was the instrument that produced the smallest increases in temperature and the mildest histologic artifacts (0.9°C; 22.8 ?m). Conclusions: The QMR blade is a useful tool in oral surgery. © 2011 Elsevier Srl. All rights reserved.
