Dens invaginatus: case report

Dens invaginatus is one of the most frequent malformations in dental elements. It can affect all teeth, even primary and supernumerary ones. It consists of an invagination of the crown surface, which happens during odontogenesis and penetrates the interior of the pulp chamber of the dental elements involved. In some cases, it can reach the apical tooth area. The maxillary lateral incisor is the most common site of occurrence. Due to its complex and variable anatomy, the tooth may present pulp necrosis and open apex, making it difficult to salvage. Oehlers classified them into types I, II, and III according to their complexity. This article reviews the literature and describes the treatment of a maxillary central incisor with type II invagination. The invaginated structure in this case detached due to various instrumentations during the change of dressing phase, facilitating root canal filling. In conclusion, this case shows that many methods are capable of removing the invaginated area of a dens invaginatus type II.
