Dens invaginatus in first mandibular premolar.
A case of dens invaginatus in a mandibular first premolar with periapical lesion is presented in which it was possible to perform non-surgical endodontic therapy. Dens invaginatus is a developmental malformation of teeth which results from abnormal morphodifferentiation. Due to their abnormal anatomical configuration, invaginated teeth present technical difficulties in their clinical management. The treatment modalities available to the clinician include: endodontic therapy, endodontic surgery, combined treatment, or extraction. In this case the treatment of choice, selected according to clinical and radiographic considerations, was endodontic therapy of the main root canal.
