Abstract
Introduction: Dimensional changes in the materials used for root end fillings could enhance or weaken the seal of the filling. The purpose of this study is to quantify and compare the dimensional changes of ProRoot white Mineral Trioxide Aggregate (Dentsply Tulsa Dental Specialties, Johnson City, TN), EndoSequence Root Repair Material (Brassler, Savanah, GA), and Biodentine (Septodont, Cambridge, ON, Canada) in a simulated root end model during setting of the respective materials. Methods: Dimensional changes of the experimental materials in simulated root ends were measured using digital image correlation. Results: The white MTA demonstrated shrinkage was from 0.86% to 2.98%, with a mean of 1.84% and standard deviation of 0.61%. Shrinkage of Biodentine was measured to be 0.43% to 1.88%, with a mean of 1.30% shrinkage and standard deviation of 0.42%. The ERRM expanded from 0.17% to 2.56%, with a mean of 1.23% and a standard deviation of 0.88%, with all samples demonstrating expansion. Conclusions: The water available during the setting of Mineral Trioxide Aggregate, EndoSequence Root Repair Material, and Biodentine has an effect on the dimensional changes of the material. White MTA and Biodentine have previously been shown to expand with adequate hydration, but may shrink in an environment that is drier.
