摘要: Abstract Several physical properties of nine commercial root canal sealers were evaluated in vitro and compared with those two experimental endodontic materials based on polycarboxylate formulations. Flow, setting time, compressive strength, radiopacity, adhesion to dentin, solubility evaluated. The zinc oxideeugenol typically low strength high solubility. These the Diaket polyvinyl resin sealer showed no dentin. epoxy AH26 superior respect flow, adhesion; this material was high. formulation significantly higher values over adhesion, reduced tensile adhesive bond dentin twice that AH26. A wide variation tested empirical nature these "sealers." Further testing is indicated.
