Regenerative Endodontics: A Potential Solution for External Root Resorption (Case Series).
Journal of endodontics(2019)
Abstract
INTRODUCTION:Regenerative endodontic procedures (REPs) are aimed to treat apical periodontitis and promote root maturation of immature necrotic teeth. However, REPs are not intended to be a primary indication for treating or arresting external root resorption (ERR). The purpose of this study was to describe REP treatment in the cessation of ERR.
METHODS:Four cases (5 teeth) of posttraumatic immature teeth diagnosed with necrotic pulp and apical periodontitis or chronic apical abscess were treated with REPs using plasma-rich fibrin as a scaffold. All the teeth showed ERR and have been followed up to 3 years.
RESULTS:This case series shows how REPs arrested ERR. In 3 of the cases, replacement resorption was arrested, thus avoiding complications of ankylosis and the need for decoronation.
CONCLUSIONS:In addition to the known advantages of REPs, we show that REPs are a promising treatment modality for arresting ERR, warranting further clinical trials.
