COMPARISON OF EFFECTIVENESS OF MINERAL TRIOXIDE AGGREGATE AND CALCIUM HYDROXIDE IN APEXIFICATION PROCEDURE
An incompletely formed apex (open apex) is one of the most common features seen in immature permanent teeth after dental trauma. Endodontic treatment of open apex teeth presents with problems of overfilling and poor apical seal, thus it is imperative to create an artificial apical barrier or to induce apical closure with calcified tissue. Different materials have been tried for Apexification procedure, the most common are calcium hydroxide and mineral trioxide aggregate (MTA). The objective of this article was to compare the effectiveness of Mineral Trioxide Aggregate and Calcium hydroxide in creating apical closure.
This is a comparative study of 80 patients with Open Apex teeth. They were randomly allotted into two groups (Group A and Group B). In Group A( 40 patients), calcium hydroxide was used as an apexification material, While in Group B ( 40 patients) apical plugs were produced with mineral trioxide aggregates (MTA) followed by obturation.
In Group A,30 patients showed complete absence of lesion while in Group B, 37 patients showed complete healing. Ten patients showed no healing in Group A, because of improper packing of material into the canal, while only three patients showed no healing in Group B because of poor delivery of MTA to the apex. The results showed that 75% teeth had complete healing in Group A and 92.5 % had complete healing in Group B. The results of the study concluded that MTA is significantly better than Ca (OH)2 in Apexification of non- vital immature permanent teeth.
