The effect of isopropyl alcohol desiccation on apical sealability of two commonly used endodontic cements.

The present study was undertaken to determine the ability of alcohol desiccation to improve the apical seal by removing residual moisture from the canal. From the results of this study, isopropyl alcohol did not improve the sealability of either Roth's 801 sealer or AH26 sealer. Thus, the employment of this technique should be questioned on the basis of the potential source of irritation of the alcohol and the addition of an extraneous procedural step.
