Calcium Silicate-Based Cements as Root Canal Medicament.

open access: yesClinical, cosmetic and investigational dentistry, 2020
This study aims to retard the setting reaction of CSC by mixing it with 2% chlorhexidine gel (CHX) which will be used as an intracanal medicament, and to evaluate the removal of the experimental medicaments from the root canal.White Portland cement, white ProRoot MTA and Biodentine were mixed with 2% CHX.

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 ...
