The experience obtained with 789 laser interventions used in oral surgery is summarized. In the first group, 756 patients were operated on by CO2 laser, in the second, 17 were treated with Nd:YAG laser, and in the third, 16 were treated simultaneously with both types of lasers. Among the outpatient interventions performed under local anesthesia were 233 precancerous conditions, 491 benign tumours, and 65 other lesions. Following CO2 laser interventions, the zone of the irreversible tissue damage did not exceed 300 μm in the instance of high energy cutting; it was almost 1 mm following Nd:YAG laser cutting, and it was 500 μm when cut by a combined laser beam. The precancerous conditions can successfully be treated by CO2 laser, especially by evaporation. The Nd:YAG laser leaves a broad necrotic zone. The combined application, however, is highly advantageous to treat vascular lesions and markedly hemophilic structures/hemangioma, epulis, tongue resection, and so forth. In oral surgery the combined use of the CO2 and Nd:YAG laser beams is extremely beneficial due to their excellent hemostatic effect.
