Abstract
The absence of a natural apical constriction in a nonvital young permanent tooth makes
endodontic treatment a challenge. There is a need to induce or create an apical barrier against,
which the obturating material can be condensed. Traditionally, calcium hydroxide is the material
of choice to induce apexification. Due to certain drawbacks such as prolonged treatment duration
and unpredictable apical barrier formation, it is being replaced by materials, which have a more
predictable outcome like mineral trioxide aggregate (MTA). One‑step apexification with MTA
reduces the treatment time when compared with traditional calcium hydroxide apexification,
which requires an average time of 12–19 months.
In one‑step apexification using MTA, the technical problem encountered is controlling the
overfill or underfill of MTA. The use of a matrix material helps to overcome this shortcoming.
Platelet rich fibrin (PRF) is an immune platelet concentrate, which can be used as a matrix, it also
promotes wound healing and repair. This case report presents a case of one step apexification
using MTA as an apical barrier and autologous PRF as an internal matrix.
