Comparação tomográfica do reparo de lesão periapical ultizando o laser de alta e baixa potência: relato de caso

Abstract

INTRODUCTION: Periradicular lesions can be symptomatic or asymptomatic, leading to extensive bone resorption when severe. Endodontic treatment aims to treat or prevent the development of these lesions. To achieve a positive outcome, it is essential to understand the internal root anatomy, considering possible anatomical variations. In addition to this procedure, the use of high and low-power lasers is applied to induce atoms or molecules to emit light at a specific wavelength. OBJECTIVE: To report a clinical case of endodontic treatment, focusing on the regression of an extensive periapical lesion resulting from a diagnosis of chronic periapical abscess, using high and low-power lasers. METHODOLOGY: This study involved a patient who required endodontic treatment

on the upper central incisors, diagnosed with chronic periapical abscess. A three- dimensional imaging examination, Cone Beam Computed Tomography (CBCT),

was performed. The treatment was carried out in multiple sessions, using additional disinfection methods with intracanal medication, agitation of the irrigating solution, and application of high and low power laser. RESULTS: It is expected that there will be regression of the apical lesion with the combined use of high and low-power laser protocols, along with intracanal medication. CONCLUSION: The use of laser in endodontics is highly relevant to modern dentistry. When combined with intracanal medication changes, it proves to be very effective in treating periradicular lesions. Thus, endodontic treatment, when performed with proper prognosis, presents a high success rate after appropriate follow-up.
