Nonsurgical endodontic treatment of dens invaginatus with large periradicular lesion: a case report.
The endodontic treatment of teeth with severe Type 3 dens invaginatus, characterized by an infolding of enamel and dentin, extending deep into the pulp cavity near the root apex, may be complicated and challenging. Because of the bizarre root canal anatomy and widely open apex, a combination of nonsurgical and surgical endodontic treatment or extraction is the most common choice of therapy. This article describes a nonsurgical endodontic treatment of a tooth with severe Type 3 dens invaginatus and an associated large periradicular lesion. After complete removal of the invaginated central mass of hard tissue and long-term calcium hydroxide treatment, nonsurgical endodontic treatment was performed. Complete healing of the periradicular lesion was observed at 25-month and 74-month follow-up examinations.
