This study characterized the interactions of mineral trioxide aggregate with a synthetic tissue fluid composed of a neutral phosphate buffer saline solution and root canal dentin in extracted human teeth using inductively coupled plasma-atomic emission spectroscopy, scanning electron microscopy, energy dispersive X-ray analysis, and X-ray diffraction. Mineral trioxide aggregate exposed to synth...

introduction : solubility of root filling materials is heavily influenced by the environment they are in contact with. this study compared the solubility of proroot mta in deionized water and synthetic tissue fluid. materials & methods: forty specimens of prepared mta were immersed in deionized water and synthetic tissue fluid (20 samples each). the solubility was assessed after 7 and 28 days. ...

The purpose of this paper was to study the reaction of rat subcutaneous connective tissue to the implantation of dentin tubes filled with white mineral trioxide aggregate (MTA), a material that will be marketed. The tubes were implanted into rat subcutaneous tissue and the animals were sacrificed after 7 and 30 days. The undecalcified pieces were prepared for histological analysis with polarize...

introduction: the purpose of this study was to compare the histocompatibility of white (wmta) and gray (gmta) mineral trioxide aggregate mixed with 0.12% chlorhexidine (chx) and distilled water (dw) in subcutaneous connective tissues of rats. materials and methods: the freshly mixed wmta and gmta with chx or dw were inserted in polyethylene tubes and implanted into dorsal subcutaneous connectiv...

introduction: candida albicans (ca) is by far the most common yeast of oral infections, including endodontic infections. the aim of this study was to evaluate and compare the antifungal effect of white-colored mineral trioxide aggregate (wmta) and portland cement (pc) using a tube-dilution test. materials and methods: wmta and pc were tested freshly mixed and after 24 h. the experiment was perf...

background and aim: formocresol (fc) is yet, the most common medication used for pulpotomy of primary teeth. however, its potential hazards including toxicity, mutagenicity and even some degrees of carcinogenicity are the remaining sources of concern to clinicians. this investigation was aimed at comparing the clinical success level of mta (case) treated pulps of primary teeth to that of formoc...

statement of problem: pulpotomy is the most common pulp treatment of primary molars. formocresol pulpotomy has enjoyed long-term clinical use and success, but concerns over its toxicity and mutagenicity have prompted research into other pulpotomy techniques. purpose: the aim of the present study was to compare the relative success of formocresol, ferric sulfate and mta pulpotomy methods in prim...
