Abstract

In this study we present the results of two techniques in a group of 50 patients with gingival hyperplasia that were treated in the department of buco-maxillary surgery and laser unit. The majority of those patients had no teeth and had an incorrect adaptation of dental prosthesis. The first group (30 patients, 40 to 55 years) were submitted to conventional surgery with local anesthesia. The second group (20 patients, 40 to 55 years) were submitted to CO₂ laser surgery with local anesthesia. We were able to verify that the group treated with CO₂ laser had much less bleeding during laser procedure, had a better tolerance, and required less anesthesia. The immediate post-operative was smoother with almost no complaint of pain since edematous and inflammatory reaction were reduced. Concerning the late post-operative, the group submitted to conventional surgery presented a high degree of recidivous hyperplasia (60%) allowing a poor or no prosthesis readaptation. In the group treated with CO₂ laser the recidivous hyperplasia occurred in only 35% allowing a much better rehabilitation. This comparative study demonstrated more benefits and effective results of CO₂ laser surgery over conventional techniques.
