Abstract

Aim

This study describes a clinical case of type III dens invaginatus with an extensive periradicular lesion treated successfully.

Background

Dens invaginatus is a maldevelopment of the dental germ which occurs as a result of the invagination of the enamel organ. These cases may present difficulties with respect to its diagnosis and treatment because of canal morphology. The success of endodontic therapy requires a knowledge of dental anatomy and its anomalies.

Case report

A 17-year-old female patient is reported presenting right maxillary lateral incisor (tooth no. 7) classified as type III dens invaginatus with necrotic pulp and presence of an extensive radiolucid lesion. Endodontic treatment was recommended for tooth. However, intracanal exudate was present, suggesting a resistant infection. Enucleation of the lesion was performed as a complementary approach. The root canal obturation was carried out by the gutta-percha thermoplastification technique with root canal sealer, followed by restoration of the tooth. Healing of the lesion with hard tissue formation was confirmed at follow-up.

Conclusion

A combination of endodontic and surgical treatments were fundamental to the maintenance of the tooth. The treatment was considered successful.

Clinical significance

Root canal therapy of dens invaginatus should be based on a thorough clinical and radiographic evaluation. The knowledge of classification and anatomical variations of teeth with dens invaginatus are of great importance for correct treatment.
