Fluid flow evaluation of Fuji Triage and gray and white ProRoot mineral trioxide aggregate intraorifice barriers.
The purpose of this study was to compare coronal leakage in teeth with 2-mm intraorifice barriers of Fuji Triage glass ionomer, gray mineral trioxide aggregate (MTA), and white MTA using a fluid flow model. Forty anterior teeth were decoronated, instrumented, and obturated. Teeth were divided into positive and negative controls and 3 experimental groups receiving 2-mm barriers of Fuji Triage glass ionomer, gray MTA, or white MTA. Fluid movement was tested 3 times for each tooth, and means were calculated. Data were analyzed with one-way analysis of variance and Student-Newman-Keuls (alpha = .05). Fluid movement means and standard deviations were as follows: Fuji Triage, 0.47 +/- 0.45 mm; gray MTA, 0.49 +/- 0.44 mm; white MTA, 0.52 +/- 0.23 mm; and positive controls, 3.57 +/- 1.13 mm. No significant differences were found among the experimental groups. However, positive controls leaked significantly more than all experimental groups at P <.001.
