Isopropyl Cyanoacrylate as a Root Canal Sealer: Cianocrilato isopropilico como un sellador deconductos

Isopropyl cyanocacrylate was evaluated as a root canl sealer by comparing it with three commercial sealers. Six groups of 20 teeth were studied: a negative control group in which apical openings were plugged with wax; a positive control group in which canals were filled with gutta-percha without any sealer; and four experimental groups in which the canals were filled with gutta-percha along with either Hydron, AH-26, Grossman, or isopropyl cyanoacrylate as root canal sealers, respectively. After obturation, the roots were immersed in India ink for 24h. The extent of leakage through the apical openings was measured. Canals filled with guttapercha in conjunction with isopropyl cyanoacrylate did not differ significantly from those in the waxplugged control group in the extent of leakage. In contrast, canals obturated with commercial sealers showed significantly more leakage (p<0.01).
