Dens invaginatus is a developmental anomaly resulting from epithelial invagination of the tooth crown before calcification. Endodontic treatment of teeth affected by dens invaginatusmay be difficult and complex due to aberrant anatomy. Combined orthograde and surgical approaches for successful treatment of dens invaginatus are effective. This report describes the successful treatmentand results atthe 12-month follow-up of a maxillary lateral incisor showing dens invaginatus type II, a large periapical lesion and an open apex by using combined surgical and endodontic treatment.

An unusual case of dens invaginatus on a mandibular second molar: a case report.
Restor Dent Endod

Faculty of Dental Surgery, University of Strasbourg, Strasbourg, France.
The present case report describes the endodontic treatment of a type III B dens invaginatus (DI) in a three-rooted mandibular second molar since the invagination invades the root and extends apically. Clinical and cone-beam computed tomography examination of the mandibular second molar showed a broadened coronal morphology, DI, a third root, periapical radiolucency, and compression of a distal root canal by the invagination, which developed an atypical semilunar shape. The tooth was diagnosed with pulpal necrosis, symptomatic apical, and peri-invagination periodontitis.

This report highlights successful management of a rare case of a mandibular premolar with Oehler's Type IIIb Dens Invaginatus (DI) and peri-invagination periodontitis with guided intentional replantation without root canal treatment. A 22-year-old female patient reported with discomfort and a sinus tract associated with tooth number 21. Clinical examination and cone beam computed tomography revealed tooth number 21 had an Oehler's Type IIIb DI with peri-invagination periodontitis.

Background: Dens invaginatus is a developmental abnormality originating from tooth development, including coronal invaginatus and radicular invaginatus. The reported incidence varies greatly due to diagnostic techniques, classification criteria and race. The incidence of dens invaginatus in China was not clear, and the impact of dens invaginatus on periodontal support tissue were rarely reported.

Unlabelled: Regenerative endodontic treatment (RET) has been suggested for the treatment of traumatized necrotic immature teeth. There are only a few reports of using RET to treat a horizontal root fracture. The aim of this paper is to describe successful regenerative retreatment in a tooth with a horizontal root fracture and dens invaginatus.

Article Synopsis
- - Dens invaginatus (DI) is a rare dental condition that occurs when the enamel organ grows into the dental papilla, making treatment and diagnosis difficult due to its unusual canal structure.
- - A case study examined a 12-year-old boy with DI affecting his maxillary lateral incisors, showcasing unique clinical and radiographic features.
- - The treatment involved sealing the invagination with flowable composite and using an etchant and bonding agent, highlighting a multidisciplinary approach that can improve patient outcomes in dental care.
