The sealing ability of ProRoot MTA when placed as an apical barrier using three different techniques: an in-vitro apexification model.

Objective: To assess the sealing ability of ProRoot MTA when placed as an apical barrier using three different techniques.

Method And Materials: Sixty freshly extracted single-rooted human teeth were decoronated and standardized to a root length of 15 mm. The root segments were prepared with Gates Glidden burs to simulate a divergent open apex of immature teeth and randomly assigned into three experimental groups of 20 samples each.

A randomized clinical trial on the use of medical Portland cement, MTA and calcium hydroxide in indirect pulp treatment.

Objectives: Studies on indirect pulp treatment (IPT) show varying success rates of 73 to 97 %. The necessity of re-opening the cavity and the question of the optimal capping material is still under debate. The aim of this prospective in vivo study was to compare the clinical and microbiological outcomes of mineral trioxide aggregate (MTA), medical Portland cement, and calcium hydroxide on the dentin-pulp complex of permanent and primary teeth treated with two-step IPT.
