Paper Abstract

The Er:YAG laser has been studied for periodontal therapies, so much for removal of the subgingival calculus and its bactericidal effects. The proposal of this study is to evaluate the effectiveness of the Er:YAG laser in root planning in comparison to the traditional method, not surgical. Six recently extracted due top the disease periodontal, were cut longitudinally tends like this two half of the root. These half were separate in four groups. The first group is the natural tooth, the second group was accomplished to rot planing with Graceycurette. And in the third to Er:YAG laser with a contact tip, using a 45 degree angle in relation to the root; in the fourth group was scraped and planed with Er:YAG laser and complemented rot planing with Graceycurette. The used energy was of 60 to 300mJ and the frequency of 10 Hz accomplished with irrigation. The obtained results were similar in the groups 2 and 3 in comparison to the amount of smear-layer. In group 4 however, better result was obtained, because the image was much more regular and with less amount of smear-layer. The conclusion of the work is that with the association of the Er:YAG laser technique and Graceycurette the results are superior to the conventional treatment.
