Trauma to anterior teeth results in crown root fracture in 5% of cases. Calcific healing of a complicated oblique crown root fracture is rarely reported in literature. This article highlights the calcific healing of a traumatized maxillary central incisor with crown root fracture. This unique observation of healing following trauma was confirmed with the use of spiral computed tomography and Hounsfield units.
