Regenerative endodontic protocol in immature teeth: clinical case reports

Regenerative endodontic treatment

Abstract

This paper aimed to describe the treatment protocol for immature teeth with necrotic pulp by inducing revascularization and using bioceramic material. Case 1 presents a dens invaginatus type I in tooth (#22) with tooth mobility, pulp necrosis and presence of fistula. Case 2 shows tooth (#35) with an atypical incomplete root apex formation. Irrigation was performed with 3% sodium hypochlorite gel, 17% EDTA, and 2% chlorhexidine digluconate in both cases. Calcium hydroxide dressing was kept in the root canals for 30 days. Then, apical bleeding was induced, root canals were filled with blood clot, and bioceramic material was placed in the cervical third. After 4-year and 2-year follow-up, clinical and radiographic evaluations highlighted periapical bone repair and tooth in function. Therefore, the long-term results suggest that the regenerative endodontic protocol used was successful and can be a therapeutic option for immature teeth with pulp necrosis.
