Comparison of Sealing Ability of MTA and Retroplast as Root End Filling Materials Evaluated under a Stereomicroscope Using Rhodamine B Dye

Abstract

Aim: The aim of the study was to compare the sealing ability of Mineral Trioxide Aggregate (MTA) and Retroplast as root end filling materials using the Rhodamine B dye penetration method in vitro. Methodology: Forty freshly extracted human single-rooted teeth were randomly divided into two groups of 20 teeth each, and standard root-end cavities were prepared in all teeth. The cavities were filled with MTA and Retroplast in groups 1 and 2, respectively. The specimens were then stored in 1% Rhodamine B dye for a week, following which the dye penetration with all samples was analysed under a stereomicroscope and scored according to Tronstad's criteria. The observations were compared with Chi square test at a 0.220 level of significance. Results: 5% of the samples in both the groups showed no significant leakage. The leakage was deeper with the Retroplast group than with the MTA group; however, there was no statistically significant difference between the two groups. Conclusion: Both MTA and Retroplast are similar in their sealing potential as root-end cavity fillings with Retroplast reporting slightly deeper microleakage than MTA within the limits of the present study.

“…Nepal et al [ 32 ] compared the apical microleakage of glass ionomer, MTA, and Biodentine by the dye penetration test using 2% methylene blue, and showed that after 72 h, MTA and Biodentine had significantly lower leakage than glass ionomer, but the difference between MTA and Biodentine was not significant. In another study, Kararia et al [ 33 ] evaluated the seal ability of MTA and Retroplast by the dye penetration test using 1% Rhodamine B. They reported that after 1 week, leakage was noted in 95% of all specimens in both groups, with no significant difference between them.…”

“…This outcome can be attributed to the outstanding sealing ability of MTA, which effectively prevents the microleakage of bacteria. In a study conducted by Kararia et al [ 27 ], a comparison was made between the sealing ability of MTA and retroplast. The researchers concluded that MTA demonstrated superior performance when compared with retroplast.…”
