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).

Chemical Stability and Bond Strength of Endodontic Sealers Exposed to Acidic, Alkaline and Protein‐Rich Environments: An In Vitro Investigation

Australian Endodontic Journal, EarlyView.
ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...

Dose‐Dependent Effects of Simulated Clinical Radiotherapy on the Structure and Properties of Root Dentine

Australian Endodontic Journal, EarlyView.
ABSTRACT Head and neck radiotherapy (HNRT) can expose teeth to moderate radiation doses, yet the effects on root dentine under clinically relevant conditions remain unclear. This in vitro study compared dentine subjected to 0, 30, or 50 Gy IMRT. Palatal roots from 35 maxillary molars were allocated to non‐irradiated, 30 Gy (oropharyngeal simulation ...

Dentifrices for preventing erosive tooth wear: An in vitro comparative study

European Journal of Oral Sciences, EarlyView.
Abstract Erosive tooth wear is a progressive condition that compromises enamel structure and requires preventive strategies. This in vitro study aimed to compare the protective effects of fluoride‐based dentifrices containing various bioactive agents on sound enamel subjected to simulated erosive–abrasive challenges.
