introduction: the aim of the present study was to evaluate the biocompatibility of two modified formulations of portland cement (pc) mixed with either titanium oxide or both titanium oxide and calcium chloride. methods and materials: polyethylene tubes were filled with modified pcs or angelus mta as the control; the tubes were then implanted in 28 wistar rats subcutaneously. one tube was left e...

apexification is a method of inducing apical closure for non-vital immature permanent teeth. during this treatment a mineralized barrier is induced [with long term calcium hydroxide (ch) treatment]; or artificially created [with mineral trioxide aggregate (mta) plug]. this article describes two cases of apexification in immature necrotic teeth treated with these two different techniques. after ...

The aim of this study was to compare the effectiveness of white mineral trioxide aggregate and gray mineral trioxide aggregate with different thicknesses and light curing glass ionomer cement when used as a barrier material in intracoronal bleaching procedures. In this study, 130 freshly extracted, caries free human permanent single rooted maxillary canine teeth were used. The teeth were random...

background and aims. mineral trioxide aggregate and calcium hydroxide are considered the gold standard pulp-capping materials. recently, portland cement has been introduced with properties similar to those of mineral trioxide aggregate. histopathological effects of direct pulp capping using mineral trioxide aggregate and portland cements on dog dental pulp tissue were evaluated in the present s...

introduction: mineral trioxide aggregate is being widely used for root end filling, pulp capping, perforation repair, and other endodontic procedures. recently, a material similar to proroot mineral trioxide aggregate (pmta) was developed in iran named root mineral trioxide aggregate (rmta) with the claim of having the exact result of original mta. the purpose of this study was to compare the a...

The histologic response to intentional perforation in the furcations of 28 mandibular premolars in seven dogs was investigated. In half the teeth, the perforations were repaired immediately with either amalgam or mineral trioxide aggregate; in the rest the perforations were left open to salivary contamination before repair. All repaired perforations were left for 4 months before histologic exam...
