sealing ability of three different materials to repair furcation perforations using computerized fluid filtration method

Background. the present study aimed to evaluate the sealing ability of three different calcium silicate-based materials in furcation perforations. methods. seventy-six human mandibular molar teeth were selected. perforations were created in the center of the pulp chamber floor. the experimental teeth were randomly divided into three groups (n = 22). perforations were repaired with mta angelus, endocem mta, or endosequence bioceramic root repair material fast set putty (bc-rrm putty). microleakage of the different repair materials to be tested was measured by computerized fluid filtration method at 24- and 72-hour intervals. results. for each time interval, no statistically significant difference was observed between the groups. for endocem mta and bc-rrm putty groups, the difference between the leakage values measured at both periods was not statistically significant (p > 0.05). however, there was a significant difference for the mta angelus group (p < 0.05). conclusion. all the calcium silicate-based materials used in the present study showed similar performance in repairing furcation perforations at 24- and 72-hour intervals. keywords: bc-rrm putty, endocem, endosequence, fluid filtration, furcation, perforation, mta.
