“…The maintenance of pulp vitality of the main canal is possible once the invagination presents no connection with the root canal system ( de Sousa & Bramante, 1998). When one of the canals is vital but there is contact between the two canals, a pulpotomy ( Kunert et al , 2017) or pulpectomy in the vital canal can be performed. In the literature, intervention in the main canal may not be necessary, especially in cases where the main canal has vital pulp or when there is no anatomical communication with the invaginated canal ( Gonçalves et al , 2002).…”

Nonsurgical endodontic management of dens invaginatus: a report of two cases

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.

This report describes the management of an uncommon case of dens invaginatus of a microdontic upper lateral incisor, with an extended apical lesion. Dens invaginatus is a developmental abnormality of a tooth where enamel and dentin fold into the pulpal space. This abnormal anatomy, and the separation of two distinct root canal spaces, complicates conventional treatment, making the apical portion inaccessible to instrumentation and impeding disinfection of the canal space. The coexistence of dens invaginatus affecting a microdontic tooth is a rare anomaly found in the literature. This case report describes a young female patient with dens invaginatus affecting a microdontic maxillary lateral incisor, combined with necrotic pulp and apical periodontitis. The conventional treatment was completed first to disinfect the coronal portion of the accessible pulpal space. At a subsequent appointment, it was completed by a surgical approach to cleanse and seal the apical part of the root canal space. The tooth was then restored, and the orthodontic treatment was initiated. One-year follow-up demonstrated a complete healing of the apical lesion.

Introduction: Dens invaginatus type 3, a severe form extending beyond the cementoenamel junction and exhibiting a second foramen into the lateral periodontal ligament or periradicular tissue. This anomaly may involve the periradicular tissue and cause pulpal necrosis and periradicular lesions. Case Report: An 11-year-old female patient was presented with slight swelling and periodic pus drainage from buccal gingiva of the maxillary left lateral incisor as her main complaint. Tooth had no pain on percussion or palpation, no color change, no caries and no mobility. Radiographic examination revealed that there was a radiolucent area on the mesial side of the coronal root. It was observed that this radiolucency was associated with apex of dens invaginatus. Because of continuous drainage through the canal, calcium hydroxide was replaced after 1 week with irrigated NaOCl. The drainage was under control after 3 weeks. Root canal treatment was applied to the malformed area by filling only the invaginated canal completely with MTA. Cavity was restored with light-cured resin composite. Results: Main pulp was kept vital and 2 years follow up showed periapical repair and absence of clinical symptoms. The patient was remained asymptomatic and pulp vitality was continued. Conclusion: Dens invaginatus is a dental malformation, which has a complicated treatment because of the complex root canal anatomy. It is very important to be able to identify and treat this dental malformation correctly.
