AN IN-VITRO EVALUATION OF THE SEALING ABILITY OF SUPER-ERA CEMENT USED AS A ROOT-CANAL SEALER

Forty-six extracted human teeth, 26 maxillary central incisors, and 20 mandibular incisors were instrumented with flared preparations, The m axillary and mandibular incisors were prepared to #50 and #30 master a pical file sizes, respectively, Ten maxillary and mandibular teeth wer e obturated with a single gutta-percha (GP) cone and Super-ERA cement, Ten maxillary and mandibular incisors were obturated with laterally c ondensed GP and Roth 801 sealer. Six maxillary incisors were used as c ontrols, Apical leakage of India ink was measured using a stereomicros cope after clearing the teeth, Results showed significantly less leaka ge in the mandibular incisors filled with GP and Super-ERA (p < 0.05). There was no significant difference in leakage when comparing the max illary central incisors (p > 0.05). In this in vitro study, root canal obturation with a single GP cone and Super-ERA showed promise as an e ffective way to eliminate or reduce apical microleakage, Further studi es are needed to test the ability to use this obturation method clinic ally.
