Use of the 940nm diode laser as a complement in the endodontic treatment of a necrotic tooth with acute periapical lesion

Objective: To report on the use of diode laser as a complementary tool in the endodontic treatment of a necrotic mandibular molar with an acute periapical lesion. Case presentation: A 38-year-old male patient presented with acute pain in the right mandibular region. Clinical and radiographic evaluation confirmed pulp necrosis and acute periapical abscess in tooth 4.6. A standard protocol of chemical irrigation with sodium hypochlorite (5%) and EDTA (17%) was used, complemented with diode laser in high power mode for disinfection and low power for photobiomodulation. Tomographic control at five months showed periapical healing and bone regeneration. Conclusion: The integration of diode laser as an adjuvant to endodontic therapy can improve tissue regeneration, making it a potential complementary tool in complex cases.
