title: Evaluation of internal sealing ability of three materials.
abstract: Thirty-six maxillary central incisors were prepared in a manner similar to nonvital bleaching procedures. They were examined with respect to the degree of procion green dye penetration of dentin with and without heating. Cavit, IRM, and zinc phosphate cement were used to evaluate their sealing ability. Cavit and IRM provided better internal sealing of the dentin than did zinc phosphate cement.
