Abstract
BACKGROUND AND AIM: Furcal perforation is one of the main causes of failure in endodontic treatments, and these perforations have a poor prognosis. The best choice for sealing perforations is bioceramic materials. The aim of this study was to compare the sealability of four mineral trioxide aggregate (MTA) materials. MATERIALS AND METHODS: In this in vitro experimental study, access cavities were prepared for 60 extracted primary teeth (ten in each group). Perforations were performed in the furcation area of all selected teeth in six groups, including negative control (without perforations), positive control (perforations left unrepaired), Angelus graphene modified mineral trioxide aggregate (AGM MTA), MTA Angelus, and cold ceramic groups. Dye extraction technique was used to compare the sealability of the four bioceramic materials. Data were analyzed using the Kruskal-Wallis test. Intergroup comparison was accomplished using the Mann-Whitney test with Bonferroni correction. RESULTS: The highest dye absorbance was related to the positive control group (0.09 ± 0.002). Among bioceramic materials, the highest mean value was observed in the AGM group (0.06 ± 0.004), and the lowest was seen in the MTA Angelus group (0.02 ± 0.004). There was a significant difference in dye absorbance between these groups (p = 0.002). CONCLUSION: Sealability of MTA Angelus was greater than that of other bioceramic materials. The lowest sealability was seen in AGM MTA. Thus, AGM MTA is not probably a good alternative in sealing furcation perforations. HOW TO CITE THIS ARTICLE: Mehdipour A, Heidari F, Nattaj MH, et al.
