Single Visit- Apexification Using Mta and Autologous PRF as an Internal Matrix. A Case Series.

Abstract

Endodontic treatment is challenging in teeth with a blunderbuss canal and an open apex due to difculties in attaining an apical seal. Nonsurgical one-step apexication using materials such as mineral trioxide aggregate has been proposed to overcome the shortcomings of the traditional longterm calcium hydroxide apexication technique. In order to create an apical plug, there has to be some matrix against which MTA can be placed. Platelet-rich brin (PRF), a second-generation platelet concentrate, can be employed as a matrix material against which MTA can be condensed. This case series aims to present the treatment of an immature tooth with an open apex using a one-step apexication using autologous PRF membrane as an interior matrix and MTA as an apical barrier.
