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...

introduction: the aim of this study was to compare the chemical compounds of white proroot mineral trioxide aggregate (wmta) hydrated at different ph environments. methods and materials: mixed samples of wmta were kept in acidic (ph=5.4), neutral (ph=7.4) and alkaline (ph=9.4) environments for 48 h. then, x-ray diffraction (xrd) analysis was performed for both hydrated and powder forms of wmta....

objectives: maintaining pulp vitality is a main goal in restorative dentistry. introduction of pulp capping agents paved the way to eliminate the shortcomings of these materials and obtain successful restorations. on the other hand, nanotechnology is an emerging field of science with increasing use in dental materials. this study sought to assess the effect of addition of nano-tio2, nano-sio2 a...

background and aims. substituting chlorhexidine (chx) for water has been shown to enhance antimicrobial activity of mineral trioxide aggregate (mta). the purpose of this study was to compare the compressive strength of mta mixed with distilled water, 0.12% and 0.2% chlorhexidine. materials and methods. mta was mixed according to manufacturer’s instructions in group i (n = 20). in groups ii & ii...

objective: in a cavity prepared through endodontic surgery, application of a material to provide apical seal and prevent bacterial and tissue exudates is of great importance. the purpose of this study was to compare the sealing ability of biocalex with white mta, gray mta, and amalgam as root-end fillings. materials and methods: sixty-six single-rooted extracted human teeth were cleaned, shaped...

objectives: mineral trioxide aggregate (mta) is extensively used in endodontics. however, mta is difficult to handle because of its granular consistency, low mechanical properties and initial looseness. the objective of this study was to assess the compressive strength (cs), diametral tensile strength (dts), and ph of set mta using methyl cellulose as liquid. materials and methods: white proroo...
