The use of cone beam computed tomography in the conservative management of dens invaginatus: a case report

Abstract

AIM: To report the use of cone beam computed tomography (CBCT) in the assessment of dens invaginatus. SUMMARY: Chronic periradicular periodontitis associated with an infected invagination was diagnosed in an immature mandibular lateral incisor tooth. A CBCT scan revealed essential information for the management of the tooth. There was no communication between the invagination and the main root canal. Endodontic treatment was carried out on the invagination. The root canal with a vital pulp was left untreated, thus allowing the tooth to mature and continue to develop. KEY LEARNING POINTS: * The true nature of dens invaginatus cannot always be estimated from conventional radiographs. * Cone beam computed tomography is a useful diagnostic tool in the management of dens invaginatus.
