HIGH-INTENSITY DIODE LASER IN ENDODONTIC PRACTICE - CLINICAL CASE REPORT

Abstract

Knowledge of root anatomy demonstrates that standard shaping procedures, intracanal medication and irrigation are not sufficient for total bacterial elimination. This study aims to demonstrate a clinical case in which chemomechanical preparation was performed, associating the usage of a high-intensity diode laser, in an attempt to regress a lesion associated to a primary infection. A 15-years old patient had an endodontic treatment initiated after demonstrating a radiolucent lesion between teeth 11 and 12. Patient did not reported pain and had a history of trauma in the anterior teeth. Percussion and vitality tests were performed, both presenting negative results. Both teeth were accessed and prepared as suggested by the standard protocols but, before the application of intracanal medication, a high-intensity laser was applied, in spiral movements to provide contact with all intraradicular walls, in a pre-established protocol of time and energy. After finishing the treatment, radiographs were taken, as well as clinical examination, after two and four months. It was observed that the use of laser as an adjunct to the endodontic treatment allowed a considerable regression of the lesion. Despite the success obtained in this case, the performance of studies is necessary to define a protocol for the application of laser.
