Endodontic therapy for dens invaginatus in a maxillary second premolar

A unique approach to endodontic therapy for dens invaginatus in a maxillary second premolar is presented. The management of the case included the placement of calcium hydroxide in the root canals for 5 months, followed by obturation with gutta-percha and sealer.

Apical closure of mature molar roots with the use of calcium hydroxide.

Calcium hydroxide may induce apical root closure in affected mature teeth as well as in immature teeth. Once an apical hard tissue barrier is formed, a permanent root canal filling can be safely condensed. Two cases are described in which calcium hydroxide induced apical root closure in mature molar teeth where the apical constriction was lost because of chronic inflammatory process.
