Surface Morphological Analysis and Evaluation of the Sealing Ability of a Nanoparticle-Incorporated Hydraulic Root-End Cement

Abstract

Since the inception of mineral trioxide aggregate (MTA), calcium silicate cements have emerged to dominate in the dental sector, mainly due to their hydraulic property. The ability of such cements to set in the presence of moisture is their most significant characteristic. A plethora of products based on hydraulic silicate cement constitution have recently entered the market; these items can be seen as MTA improvements attempting to minimize MTA’s shortcomings. Despite any possible benefits, the capacity to seal in an endodontic root repair material is, however, the most significant aspect determining its success. An experimental calcium silicate-based cement incorporated with nanosilver was fabricated to evaluate the sealing ability and to compare with the existing commercially available MTA. Teeth were decoronated and root canal treatment was performed. Root-end resection and cavity preparation, followed by root-end filling was done with the materials. Confocal scanning microscopy was used to assess the extent of rhodamine dye leakage in the root-end cavities. The results showed that both the experimental nanosilver incorporated calcium silicate-based cement and Mineral Trioxide Aggregate showed microleakage under a confocal microscope.
