“…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.

Aim:The aim of this study was to determine the prevalence of dens invaginatus in a sample of Turkish dental patients.Materials and Methods:The sample included 6, 912 panoramic radiographs from different Turkish dental patients. The ages of the patients ranged from 18 to 50 years. A tooth was considered having dens invaginatus if an infolding of a radiopaque ribbon-like structure equal in density to enamel was seen extending from the cingulum into the root canal. Maxillary and mandibular teeth were evaluated on panoramic radiographs to determine the type of dens invaginatus using Oehlers’ classification.Results:The overall incidence of patients with dens invaginatus was 0.17%. Dens invaginatus were detected in 15 teeth of a total of 192 150 teeth to give a tooth prevalence of 0.008%. Maxillary lateral incisors were most commonly affected teeth in the mouth (80% of cases), followed by maxillary canine teeth (20% of cases). The bilateral incidence of a symmetrical distribution was 25%.Conclusion:The occurrence of dens invaginatus among this Turkish population was rare. Attention should be paid to the presence of dens invaginatus and the treatment problems associated with it.
