Abstract

Background: Dens invaginatus is a developmental anomaly that often presents significant diagnostic and therapeutic challenges, especially in Type IIIb cases. This report describes the successful non-surgical endodontic management of a maxillary lateral incisor with Type IIIb dens invaginatus.

Case Report: A 16-year-old female presented with pain and swelling associated with tooth #12. Clinical and radiographic evaluation revealed a Type IIIb dens invaginatus with a large periapical lesion. CBCT imaging confirmed the invagination extending through the root with a lateral exit. Non-surgical endodontic treatment was performed [1], including cleaning, shaping, calcium hydroxide dressing, and single cone technique obturation with bioceramic sealer.

Outcome: At 6-month follow-up, the tooth was asymptomatic with visible radiographic healing.

Conclusion: Non-surgical endodontic therapy can be an effective treatment option for Type IIIb dens invaginatus when supported by CBCT assessment and meticulous endodontic technique.
