Background: Dens invaginatus is a developmental dental anomaly resulting from an invagination of dental tissues folding from the outer surface towards dental pulp. The aim of this systematic review and meta-analysis was to determine the prevalence of dens invaginatus using cone beam computed tomography (CBCT).
Material And Methods: A systematic review was conducted following PRISMA statements. The research question was: What is the prevalence of dens invaginatus in the adult population assessed by CBCT? The MeSH terms were used to search articles published in the electronic database PubMed. Studies were selected considering predetermined eligibility criteria. The Robins-I tool developed by Cochrane was used to assess methodological quality and risk of bias.
Results: Four studies were included in this systematic review, including 2009 CBCT images. The overall prevalence of dens invaginatus was 9.0% (95% CI = 7.2 - 10.8%; < 0.001). Three studies were considered of low risk of bias.
Conclusions: The results of this systematic review and meta-analysis show that prevalence of dens invaginatus using CBCT was higher than previous estimations carried out with conventional radiographs. Therefore, an early identification and a correct management of invaginated teeth is essential for improving the prognosis of these teeth. It can be concluded that teeth with dens invaginatus should always be studied using CBCT. Dens invaginatus, Dens in dente, Dental anomalies, CBCT, Cone beam computed tomography.

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.
Endodontic management of a rare case of Type III Dens invaginatus in a maxillary canine combined with a previous occurrence of dental trauma.

Dens Invaginatus (DI) is a developmental anomaly which eventually leads to pulp necrosis and has several clinical implications in sufficient instrumentation and obturation of the root canal system. The present clinical report presents a rare case of a maxillary canine affected with DI leading to pulp necrosis combined with a previous dental trauma, which also led to irreversible pulp damage of the adjacent lateral incisor. A 14-year-old male patient with a history of dental trauma at the right maxillary region, one year earlier, was referred with pain and swelling at the apical area of the right maxillary canine.

Background: Regenerative endodontic procedures (REPs) are innovative treatments aimed at restoring damaged dental structures. However, the effect of orthodontic movement on REP-treated teeth is not well understood and may have significant long-term consequences. This study aimed to evaluate the impact of orthodontic movement on a mature permanent tooth associated with dens invaginatus that has undergone a regenerative endodontic procedure (REP).

Abstract: Dens invaginatus (DI) is a congenital dental anomaly characterized by the presence of a tooth that resembles a "tooth within a tooth." Conversely, dens evaginatus (DE) is a developmental anomaly distinguished by an additional tubercle or cusp on the tooth's crown.
