title: Use of mineral trioxide aggregate in the open apex of a maxillary first premolar.
abstract: Mineral trioxide aggregate (MTA) has shown potential as a root-end filling material. This clinical case describes the successful treatment of a premolar with an open apex using MTA and the warm gutta-percha technique. The results suggested that MTA may be used as an apical filling material in permanent teeth with multiple canals.
