• Comparison of physical and mechanical properties of mineral

    Abstract. Background: Mineral trioxide aggregate (MTA) fulfills many of the ideal properties of the rootend filling material. However, its low cohesive property often makes it difficult to handle. Biodentine, new calciumsiliebased cement has been developed to improve some MTA drawbacks such as its difficult handling property and long ...
