Sealing quality of instruments cemented in root canals with polycarboxylate cements

Abstract

Stainless steel files were cemented in place as the master cone with Durelon, PCA, and Proco-sol. The treated teeth were immersed in, dye; after 2, 4, 8, and 16 days, they were examined for evidence of dye penetration. The depth of dye penetration for each group was compared with the use of the t test. The results showed that none of the test groups belonged to the same general distribution. Although PCA sealed better than Durelon, both were considered unsatisfactory when compared to Proco-sol.
