Idiopathic Intracoronal Resorption of Permanent Molars: A Report of Two Cases

Intracoronal resorption (IR) is a condition characterized by the presence of lesions in the dentin of unerupted or erupting teeth, usually located just below the enamel-dentin junction in the occlusal part of the crown. This article presents two cases of IR-one with and one without pulp involvement. In both cases, the teeth were asymptomatic, and the lesions were discovered during routine checkups. The first case presents pre-eruptive IR with pulp involvement in an immature mandibular molar. To preserve the vitality of the growth zone and complete root development, vital pulp therapy was performed through total coronal pulpotomy and application of Biodentine. The second case is also of a mandibular molar with incomplete root development, but although it initially resembled invasive cervical resorption, treatment revealed that the granulation tissue was surrounded by intact enamel and did not affect the pulp or root of the tooth. No carious lesion was found. The tooth was conventionally restored with a composite filling.
