Management of 2 teeth diagnosed with dens invaginatus with regenerative endodontics and apexification in the same patient: A case report and review

摘要

Introduction This review and case report present the treatment of a 10-year-old boy with both permanent maxillary lateral incisors demonstrating Oehlers type II dens invaginatus and pulpal involvement. Treatment was complicated by dental anxiety, supraventricular tachycardia, immature tooth development, and facial cellulitis. Methods An infected necrotic pulp of the permanent maxillary left lateral incisor was treated by apexification and endodontic treatment with mineral trioxide aggregate. The necrotic pulp of the permanent maxillary right lateral incisor was treated with canal debridement and dressing under general anesthesia. Results Periapical healing of both teeth occurred, with the right lateral incisor showing continued root growth, thickening of the dentinal root walls, and completed apex formation. This tooth responded normally to pulp testing. Twenty-eight months after initial treatment, the right lateral incisor displayed progressive sclerosis of the canal. Conclusions This case demonstrates possible pulpal regeneration of an infected maxillary right lateral incisor with dens invaginatus and an immature apex after minimal canal debridement.
