Apexification of permanent immature teeth using MTA – a report of cases

Abstract

Immature permanent teeth with necrotic pulp require endodontic treatment different than conventional procedure. Proper root canal treatment and correct filling of such teeth is hardly possible due to open wide apices. Apexification is a method that enables to create hard apical barrier. Until recently the most common material in this method was calcium hydroxide. It is highly effective, however using calcium hydroxide requires long time treatment up to 24 months with many appointments to create mineral apical barrier. This may lead to fracture of the root`s thin walls end tooth extraction. Currently, the MTA (Mineral Trioxide Aggregate) preparation is recommended in the apexification procedure to close open apex of immature teeth. It enables to carry out apexification procedure during one or two appointments. The aim of this study is to describe 5 cases of apexification in posttraumatic and due to caries non-vital immature teeth using MTA. In the following period of observation in all the presented cases a positive treatment result was obtained. In all the presented cases a positive treatment result was obtained.
