title: Importance of clinical examination and diagnosis. A case of dens invaginatus.
abstract: A case report is presented that shows a radiolucent lesion between the maxillary left lateral incisor and canine tooth, both of which were vital. The cause of the lesion was initially unclear. The patient was to be treated surgically, however, precise examination made it clear that the cause of the radiolucent lesion was due to the exposure of a second canal because of attrition of the lateral incisor crown. The final diagnosis of the tooth was dens invaginatus. This case highlights the importance of careful examination and correct diagnosis.
