Comparative evaluation of microleakage of mineral trioxide aggregate and Geristore root-end filling materials in different environments: An in vitro study

Abstract

Aim:The aim of this in vitro study was to evaluate and compare the microleakage of mineral trioxide aggregate (MTA) and Geristore root-end filling materials in different environments.Materials and Methods:After removing the anatomical crowns of ninety extracted human maxillary central incisors, their root canals were instrumented and obturated. The apical 3 mm of each root was resected, and a standardized root-end cavity was prepared using an ultrasonic tip. The roots were alienated into three equal subgroups for each material and the root-end filling was performed in different environments namely dry, saliva contaminated, and blood contaminated. Samples were immersed in 0.2% Rhodamine B dye for 48 h. Roots were sectioned longitudinally and examined under a fluorescent microscope to measure the linear dye penetration. The results were statistically analyzed using analysis of variance and Tukey's honestly significant difference post hoc test.Results:The Geristore dry group illustrated the lowest linear leakage, while the MTA saliva-contaminated group illustrated the highest leakage. In dry environment, linear dye penetration of both MTA and Geristore groups did not show any significant difference. However, statistically significant difference was observed between MTA and Geristore groups in blood- and saliva-contaminated environments.Conclusion:Geristore showed better results in saliva- and blood-contaminated environments; hence, Geristore may be used as an alternative to MTA for root-end filling.

“…In another neoteric study, Pandey et al 50 comparatively evaluated the microleakage of MTA and Geristore in dry, saliva, and blood-contaminated environments and found Geristore equally effective as MTA in a dry environment but provided a better apical seal than MTA in saliva and blood-contaminated environments.…”

Calcium silicate and calcium aluminate cements for dentistry reviewed

“…When the pulp is so compromised it must be removed to relieve the pain, root canal therapy may be performed wherein the pulpal tissue is removed and replaced with other materials; however, even root canal materials and methods may allow bacterial microleakage. [15][16][17][18][19] The alternative to root canal therapy is tooth extraction to reduce the pain and disease. Although partial or full dentures and dental implants are tooth replacements, they lack the benefits of natural teeth.…”
