Dens invaginatus in primary maxillary molar: a rare case report and review of literature

Treatment opinions for dens invaginatus: A case series

Dens invaginatus (DI) is a rare congenital dental malformation characterized by enamel or cementum folded into dentine. Such teeth are susceptible to caries, pulp infection or necrosis and periradicular lesion. The complex anatomy of this disease results in difficult treatment and a high rate of therapeutic failure. Therapeutic options, such as debriding and filling invagination, root canal treatment (RCT) and intentional replantation, vary according to the morphology and infection of the involved tooth. The present study reports five cases of DI with chronic apical periodontitis. The treatment strategies and procedures, including RCT, removing the invagination, intentional replantation and surgical treatment, are discussed according to the classification and the condition of pulp and periapical tissue. The study also reports the prognosis: All patients were followed up for ≥12 months and all teeth demonstrated periapical healing and clinical asymptomatic. In summary, appropriate treatment is based on accurate analysis of the anatomical variation in different types of DI and intentional replantation is a reliable and viable treatment to preserve the tooth.

Conservative management of dens in dente

Dens Invaginatus (DI) or dens in dente is an uncommon anomaly which mostly affects permanent lateral incisors, and it is very rare in molars. This article presents the conservative endodontic management of four different cases of DI and a discussion of the endodontic literature for this malformation. Three upper lateral incisors Type II, IIIa and IIIb, and an upper first molar Type II are shown. The most conservative approach possible was carried out. Three of the cases were obturated using the continuous wave technique. In one of the cases, it was possible to treat only the invagination with MTA and preserve the pulp vitality of the main canal. To make a correct diagnosis and to treat in the most conservative way possible, a DI is necessary to know its classification and use tools such as CBCT and magnification.

A Rare Case of Radicular Dens Invaginatus (Dens in Dente) in a Dog

A rare case of radicular dens invaginatus (dens in dente) was found during dental cleaning of a 5-year-old male Rottweiler dog. Radiographic examination revealed intense radiopacity, which extended from the crown to the apical root region of the affected tooth. Macroscopically, the crown of the left maxillary first molar tooth (209) had irregular and deformed buccal and lingual surfaces. Microscopic examination revealed dentine invagination in the pulp cavity in of the crown and root and pulp necrosis. Based on the gross, radiographic and histological findings, a diagnosis of radicular dens invaginatus was made.

Dens invaginatus (dilated odontome) in mandibular canine

Dens invaginatus is a developmental malformation of teeth related to shape of the teeth. Affected teeth show a deep infolding of enamel and dentin starting from the tip of the cusps and may extend deep into the root. It results from the invagination of the enamel organ into the dental papilla before calcification has occurred. Teeth most affected are maxillary lateral incisors. The presence of dens invaginatus in mandibular canine is extremely rare. The tooth was symptomatic in that it was mobile and was oriented horizontally. This article presents a case of symptomatic dens invaginatus in mandibular canine.
