“…Furthermore, substantial postoperative clot formation was observed. The poor treatment outcome in control teeth is in part attributed to the presence of an extrapulpal blood clot after pulpotomy, preventing direct contact of the calcium hydroxide, antibacterial capping agent, with the underlying pulp tissue (9,28).…”

Background:The purpose of this research was to evaluate the factors affecting the outcome of localized laser pulp surgery in the canine model. Study Design/Materials and Methods: Pulpal exposures 2 mm and 5 mm in diameter were prepared in eight healthy teeth in each of five dogs. The total of 40 teeth were left open to infection from the oral cavity for 3 hours or 72 hours; 2-3 mm of surface pulpal tissue were then removed using a fresh diamond bur or a CO 2 laser emitting @ 9.3 m, at 3.5 W average power in the Superpulse mode. Teeth were monitored clinically and radiographically by one blinded, pre-standardized clinician for 3 months. Results: Chi-square test and Fisher's Exact test (2-tail) results associated laser treatment with significantly better clinical and radiographic outcome (P < 0.001). Using regression analysis, duration of pulpal exposure to contamination by the oral environment was identified as primary determinant for treatment outcome within the laser-treated and control groups (P = 0.0018). Conclusion:Clinical preconditions significantly affect the outcome of pulp surgery treatments.

The experience obtained with 789 laser interventions used in oral surgery is summarized. In the first group, 756 patients were operated on by CO 2 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 CO 2 laser interventions, the zone of the irreversible tissue damage did not exceed 300 mum in the instance of high energy cutting; it was almost 1 mm following Nd:YAG laser cutting, and it was 500 mum when cut by a combined laser beam. The precancerous conditions can successfully be treated by CO 2 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 CO 2 and Nd:YAG laser beams is extremely beneficial due to their excellent hemostatic effect.
