Apexification with calcium hydroxide has become the standard treatment choice to provide an apical stop and avoid possible overfilling.
The main purpose of apexification is to induce the formation of a mineralized barrier at the apex so that the obturation materials do not get thrown into the periapical tissues. However, it is a very time-consuming procedure.
Mineral Trioxide Aggregate (MTA) has been indicated as a suitable material for apexification of immature roots based on its ability of inducing hard tissue formation.
