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. The ulceration is often deep and shows spontaneous but delayed healing. If proper treatment is not instituted on time, the necrosis can reach deep into the bone causing sequestrum formation and ultimately leading to palatal perforation. Here, we report a case of palatal perforation in a male patient followed by surgical interventions and follow-up.

Odontome is most common benign odontogenic tumour. Radiographically and histologiclly it is characterized by production of mature enamel, dentin, cementum and pulp tissue. The structural relationship vary from nondescript mass of dental tissue referred to as complex odontome and multiple well-formed teeth (denticles) known as compound odontome. Odontomes are often found during routine radiographic investigations and are the most common cause of delayed eruption of the permanent teeth and sometimes it may itself erupt in the oral cavity. We are presenting a case series of complex odontomes with varied clinical features and radiographic appearances which may be helpful for the clinician to achieve accurate diagnosis in order to avoid subsequent complications.
