Necrose de palato por excesso de anestésico local: relato de caso clínico.

Necrosis of the hard palate is an uncommon yet significant complication that can occur due to the improper use of local anesthetics during dental procedures. The objective is to present a clinical case report of a patient treated at the dental clinic of the Afya Centro Universitário São Lucas presenting with a clinical presentation of aseptic necrosis of the palate with a history of extensive surgery involving complications. This is a case of a necrotic lesion in the palatal region after receiving multiple local anesthetic injections during dental treatment. Clinically, an ulceration was observed, accompanied by tissue loss and exposure of the bone in the hard palate. The diagnosis was made through the analysis of clinical features and the exclusion of possible infectious or systemic causes. Treatment included the administration of medications to relieve pain, followed by low-level laser therapy sessions every two days, which led to complete healing in two weeks. We conclude that laser therapy is highly effective, eliminating the need for surgical intervention, alongside the use of proper anesthetic techniques respecting the recommended maximum dose, to avoid iatrogenic complications and expand knowledge and awareness regarding complications arising from the improper use of local anesthetics.
