“…Although the teeth in the reported cases were in the maxilla, the present case was found in the mandible. [9][10][11] Embryologic timing of these two anomalies is different. Gemination occurs during the initial stage of tooth development, and DI occurs somewhat later during morphodifferantiation.…”

Aim:To present a case of a concomitant occurrence of dens invaginatus (DI) and gemination in a mandibular left lateral incisor.Background: DI is a developmental anomaly resulting from the invagination of a portion of a crown in the enamel organ stage of odontogenesis. It is commonly found in the maxillary lateral incisors but also occurs in the central incisors, premolars, canines, and molars in descending order of frequency. The occurrence of DI in the mandible is extremely rare. Gemination results from one tooth bud attempting to split into two. Geminated teeth present with a single root structure and rarely occur in mandibular teeth. Report:A 13-year-old girl presented with a chief complaint of spontaneous nocturnal pain in the mandibular left lateral incisor tooth. Intraoral examination revealed the tooth was enlarged with a notch on the incisal edge extending to the coronal 1/3 of the crown. The radiological examination revealed a Type 2 DI in a Type I geminated mandibular left lateral incisor. Summary: DI is clinically significant due to the possibility of the pulpal involvement; pulpitis, necrotic pulps, and chronic periapical lesions are often associated with this anomaly without clinical symptoms. Clinicians should be mindful of the possibility of DI when a tooth presents pulpitis without history of trauma or caries and examine the suspicious tooth and the periodontium radiographically.

“…Bilateral occurrence of this condition is frequently seen (5,13). There are several reports of dens invaginatus associated with other abnormalities such as taurodontism, microdontia, gemination, supranumerary tooth, and dentinogenesis imperfecta (13)(14)(15)(16). Teeth with dens invaginatus are often recognized clinically because of their unusual crown form.…”

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.

“…Morfis and Lentzari (8) do not speculate on the cause of clinical crown form of the tooth involved whereas Nazif and Laughlin (9) ascribe the enlarged clinical crown to gemination and claim the concommitant development of gemination and dens invaginatus to be "extremely rare". A similar case of gemination and dens invagination in a permanent maxillary lateral incisor has been described (10). A somewhat similar case has been ascribed as a result of trauma (11).…”
