Possibility of "Spongio cement" usage for root canal opturation

Abstract

The aim of this study was to evaluate of apical and canal opturation quality of polymethyl metacrylate based material for canal opturation. Investigations were included 60 extracted human single root teeth. Root canals were opturated by standard endodontic technic with three different materials. Teeth were decalcificated and enlightened in 2% methyl salicilate solution. Linear dye penetration was measured with bynocular magnifying glass with 25x magnification. Results showed that the highest apical dye penetration in canals opturated with PMMA based material in relation of AH-26 and Sealapex. Middle value of linear dye penetration in canals opturated with PMMA based material where smear layer was removed was significantly les then in group of teeth where smear layer present.
