Aim: This report describes the clinical management of a dens in dente type 3 in a maxillary lateral incisor with five canals and acute apical periodontitis in a ten years old child.
Summary: An upper lateral incisor presenting dens in dente type III necrotic pulp and acute apical periodontitis was treated. After antibiotic therapy, root canal treatment was initiated and five root canals were located, four converging to an apical pulp chamber. All canals were enlarged using hand files, irrigated with sodium hypochlorite ultrasonically activated. Calcium hydroxide was placed into the canals. The patient missed his next appointment. Eight months after, the canals were re-instrumented, and calcium hydroxide was placed again. Three weeks later the five canals were filled with gutta-percha and an epoxy resin sealer, using a warm technique. Four of the canals were interconnected. Dens in dente was restored with a metal cast post with three retainers and a full porcelain crown. After three years, the periapical lesion showed healing.
Key learning points:
- Despite its very complex anatomy type III dens in dente can be successfully treated with conventional root canal treatment.
- To achieve success in each particular case when root canal therapy is needed, the clinician should be aware of the diverse clinical techniques available. The use of magnification with clinical microscope, ultrasonic activated irrigation, use of intracanal medication, and warm filling technique are encouraged.
- A restoration with a specific cast post, with three retainers, was used due to its particular root anatomy.
