ABSTRACT
Unique anatomical deviations in canal structure are rare in anterior teeth, especially central incisors, and thus risk being overlooked. For successful intervention, a meticulous diagnostic procedure and treatment plan, significantly aided by cone-beam computed tomography (CBCT), are crucial. The case at hand explores the management of a maxillary left central incisor in a cleft palate patient, characterized by multiple developmental lobes, a bulbous crown, and an atypical root anatomy. The primary symptom was pain, accompanied by a history of trauma at age 8 years and ensuing tooth discoloration. Initial evaluations, augmented by CBCT, revealed pulpal necrosis in a single-rooted tooth with three distinct canals. Initial clinical examination was supplemented by electrical pulp testing, RadioVisioGraphy (RVG), and CBCT, after which the root canal therapy was initiated. Informed consent was obtained from the patient. The access cavity preparation resulted in a three-orifice cavity. Subsequently, the canals were enlarged and sufficiently debrided. Calcium-hydroxide was applied for 2 weeks before the commencement of apexification and obturation, followed by esthetic rehabilitation. This case highlights the importance of recognizing rare anatomical variations in anterior teeth and demonstrates the invaluable role of CBCT in both diagnosing and managing such complexities.
