Abstract

Introduction:

This case report presents the treatment of a 16-year-old boy with a maxillary lateral incisor (tooth #10) presenting with Oehlers type II dens invaginatus and diagnosed with previously initiated therapy and asymptomatic apical periodontitis.

Methods:

A regenerative endodontic procedure (REP) was performed for the tooth but complicated by apically displaced mineral trioxide aggregate (MTA). Clinical and radiographic examination was undertaken yearly, and a cone-beam computed tomography scan was taken to investigate further the formation of hard tissues within the root canal. Subsequently, tooth #10 was re-accessed and then root-filled with MTA.

Results:

There was complete periapical healing, thickening of the dentinal root walls, and completed apex formation 3 years after REP. Hard tissue formation was noted within the root canal, on the root canal wall, and the root apex through clinical and radiographic examination. Less hard tissue formation was noted on the labial root canal wall where the displaced MTA was located, which was identified on the cone-beam computed tomography scan.

Conclusions:

This report demonstrates that REP can potentially provide excellent treatment outcomes for structurally compromised teeth. REP should be considered as a first-line treatment before proceeding with a root filling when root development is incomplete, but attention to technical detail is essential.
