An in vitro dye leakage study was performed to compare the apical microleakage of Ketac-Endo root canal sealer with that of Roth's 801E and AH26 sealers. Sixty-four single-rooted human teeth were instrumented and randomly divided into four groups. Three groups were obturated with laterally condensed gutta-percha and either Roth's 801E, AH26, or Ketac-Endo as the sealer. A fourth group was obturated using a single master cone and the Ketac-Endo sealer. The teeth were suspended in 1% methylene blue dye for 6 days. The teeth were then longitudinally sectioned and evaluated for linear apical dye penetration. In general, Ketac-Endo root canal sealer showed greater dye penetration than Roth's 801E and AH26. There was no statistical difference in leakage between the laterally condensed Ketac-Endo group and the single-cone-obturated Ketac-Endo group.

D008709 Methenamine An anti-infective agent most commonly used in the treatment of urinary tract infections. Its anti-infective action derives from the slow release of formaldehyde by hydrolysis at acidic pH.
