Contemporary endodontic treatment choices for adult patients with dens evaginatus and apical periodontitis: a case report with a 2-year follow-up.

Dens evaginatus (DE) frequently leads to pulp exposure and subsequent pulpal inflammation, pulpal necrosis, and periapical inflammation. This case report describes the application of regenerative endodontic therapy and mineral trioxide aggregate (MTA) apexification in a 22-year-old man with mandibular second premolars affected by DE and apical periodontitis. Regenerative endodontic therapy was performed after thorough debridement and placement of calcium hydroxide in the root canal of the left premolar. In contrast, an apical plug of MTA was placed prior to gutta percha compaction in the root canal of the right premolar. Both teeth were restored with adhesive composite resin. A 2-year follow-up examination revealed complete periapical healing.
