Prevention of Tooth Discoloration Due to Calcium-Silicate Cements: A Review

open access: yesDental Hypotheses, 2019
Introduction: Mineral trioxide aggregate (MTA) and other calcium silicate cement similar to that are widely used in endodontic treatments. One of the widely emphasized disadvantages of these cements are the induction of tooth discoloration.

Novel Calcium Zirconate Silicate Cement Biomineralize and Seal Root Canals [PDF]

open access: yesMaterials, 2018
This study evaluated the sealing ability of gutta-percha (GP) with a calcium silicate-based sealer and a novel calcium zirconate containing calcium silicate cement (ZC). The root canals of the extracted premolars were prepared, which were then randomly allocated to three experimental groups (12 root canals per group) for obturation by continuous wave ...
