The purpose of this study was to compare the sealing ability gray mineral trioxide aggregate (GMTA), white MTA (WMTA), and both Portland cement as furcation perforation repair materials. A total 120 human mandibular first molars were used. After root canal obturation preparation furcal perforations specimens randomly divided into four groups 25 teeth each. In A, B, C, D filled with WMTA, GMTA, cement, type II respectively. Ten used positive controls no filling materials in 10 complete coverage two layers nail varnish negative controls. protein leakage model utilizing 22% bovine serum albumin (BSA) for evaluation. Leakage noted when color conversion reagent observed. behaved expected. found samples from group B other (white cement). There statistically significant differences between GMTA WMTA or but observed groups. It concluded that cements have better than MTA, can be recommended if present results are supported by vivo vitro studies. (J Oral Sci 51, 601-606, 2009)
