Laboratory Evaluation of the Physicochemical Properties of Novel Pre‐Mixed Putty‐Type Bioceramic Materials

Australian Endodontic Journal, EarlyView.
ABSTRACT This study aimed to compare the physicochemical properties of EndoSequence Root Repair Material (ERRM) Fast and CeraPutty with ProRoot MTA and Biodentine, focusing on setting time, radiopacity, microhardness, and pH. Setting time was measured using a Gilmore‐type indenter applied every 5 min until no indentation was observed (n = 15 per group).

Influence of Drying Protocol on the Setting and Crystalline Phase Formation of Calcium Silicate‐Based Sealers

Australian Endodontic Journal, EarlyView.
ABSTRACT The objective of this study was to assess the hydration, crystalline structure, and setting of bioceramic ready‐to‐use and powder/liquid sealers in dry and wet root canal dentine. Thirty‐two single‐rooted human teeth were embedded in acrylic resin and sectioned into 2‐mm segments.

Effect of Resin Coating on Dentin Bond Strength Under Immediate and Delayed Cementation Protocols

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study aimed to evaluate the effects of resin coatings on bond strength using immediate and delayed cementation protocols. Materials and Methods One hundred twenty dentin specimens were assigned to four groups: Noncoated, TK–100B (a novel single‐bottle adhesive), Hybrid Coat II, and Clearfil SE bond 2. The specimens of the latter
