Palatal Necrotic Ulcer Following Local Anesthesia: A Rare Complication

The everyday practice of dentistry relies heavily on achieving adequate local anesthesia. Even though the safety record of
local anesthetic agents is high, complications do occur. Palate is a favorable site for soft-tissue lesions. Various factors
such as direct effects of the drug, blanching of the tissues during injection, relatively poor blood supply, and reactivation
of the latent forms of herpes can all promote to tissue ischemia and a lesion in the palate. Among various complications,
anesthetic necrotic ulcer is a rare and uncommon condition occurring mostly in the hard palate possibly after a local
anesthetic infiltration. We report a case of palatal ulceration in a female patient after the administration of a local anesthetic
to the right posterior hard palate and follow-up
