Dens Invaginatus

Endodontic treatment of two maxillaryincisors with dens invaginatus is reported. Invaginated teeth present technical difficulties with respect to their management because of complicated canal morphology. This case was treated by conventional root canal treatment. The signs and symptoms ceased after the treatment. At follow up examination after 18 and 20 month the teeth were asymptomatic and radiographically showed sound periodontal and periapical tissue.

Dens Invaginatus

Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. This report presents regenerative endodontic treatment of a necrotic immature tooth with Oehler’s type III dens invaginatus of a nine-year-old female patient. A diagnosis of dens invaginatus (Oehler’s type III) and a large periapical lesion was established with the aid of cone-beam computed tomography (CBCT). In the presented case contrary to the classic revascularization protocol, mechanical instrumentation was performed which apparently did not interfere with the regeneration process. After mechanical instrumentation of the invaginated canal by manual K-files, the invaginated canal space was disinfected by triple antibiotic paste followed by blood clot induction from the periapical tissues and the placement of mineral trioxide aggregate. At one-year follow-up, the tooth remained clinically asymptomatic. Radiographic examination revealed complete healing of the periapical lesion. At the 20-month follow-up, the radiographic examination also showed that the open apex was closed and the walls of the root canal were thickened.

Dens Invaginatus

SummaryBackground/Aim: Dens invaginatus is a developmental anomaly of teeth. The endodontic treatment of these teeth may be difficult because of adversity in accessing the root canals and also complicated variations of internal structure. In this case, the report is presented the nonsurgical management and follow-up of a tooth with class II dens invaginatus with an open apex and sinus tract.Case Report: In the radiographic examination, there are two root canals; a primary (main) canal and an invaginated canal. The main canal wide-open at the portal of exit and associated with a large chronic periapical lesion extending to the apex of the maxillary left central incisor. An invaginated canal was not reaching the apex. In a clinical examination, a sinus tract was detected in the labial gingiva. After apexification with using MTA was applied, the endodontic treatment was completed. In 12 month recall, a gray discoloration was detected and internal bleaching with 35% hydrogen peroxide was applied. Finally, the tooth was restored using composite resin. 12 months follow-up radiographs revealed resolution of periapical radiolucency, trabecular bone formation, and closure of the root apex with the totally asymptomatic tooth.Conclusions: The case report shows that tooth with DI that has wide apex and sinus tract can be treated with non-surgical methods, such as immature tooth without anomalies.

Dens Invaginatus

Dens invaginatus is a malformation affecting mainly the superior lateral incisors. It is defined as an infolding of the crown hard tissues, including the enamel and dentin, and can extend up to the root apex. Root canal treatment of this abnormality is considered difficult due to the complex anatomy presented by these teeth. This case series presents nonsurgical endodontic treatment in two cases of dens invaginatus (type II and III) in maxillary lateral incisors. This nonsurgical or conventional endodontic treatment results in healing of the periapical lesions associated with both cases, with no need for extra intervention e.g. surgical or invasive management. The manual instrumentation associated with sodium hypochlorite and calcium hydroxide were able to completely heal the lesions. Radiographic exams were carried out to control and asses the healing. Nonsurgical treatment was successful in both cases with adequate repair after a 6-year follow-up with radiographic and tomographic assessments.

Dens Invaginatus

Dens invaginatus consists of a malformation that occurs during the tooth development phase. More-severe cases may affect both the crown and the root. The endodontic treatment is more complex and challenging. The purpose of this article is to report the nonsurgical endodontic treatment of a mandibular canine diagnosed with an Oehler’s dens invaginatus type IIIb with an acute periapical abscess. The treatment consisted of treating the invagination while maintaining the vitality of the pulp tissue. A radiographic six-month follow-up confirmed the apical pathosis’s resolution, while the clinical evaluation confirmed the maintenance of a healthy pulp. The endodontic treatment can be successfully performed when an early and correct diagnosis is established. Cone-beam computerized tomography and magnification are extremely useful when approaching such cases.

Dens Invaginatus

Dens invaginatus is a rare malformation of the teeth resulting from the invagination of the tooth crown before biological mineralization occurs. In most cases, the thin or incomplete enamel lining of the invagination cannot prevent the entry of bacteria into the pulp, which leads to pulp necrosis with an eventual periapical inflammatory response. The treatment options include preventive sealing or filling of the invagination,root canal treatment, endodontic apical surgery and extraction. The root canal treatment of such teeth is often complicated because of their anatomical complexity. This case describes a successful non-surgical endodontic treatment of a maxillary lateral incisor with type 2 dens invaginatus with a large periradicular lesion. At follow-up examinations after 6 and 12-months, the tooth was asymptomatic and the healed lesion was evident radiographically.
