Evaluation of the physicochemical properties and adhesive interface quality of BioRoot Flow and BioRoot RCS endodontic sealers: An in vitro study

Dione Tavares Reis, Gustavo Alexandre de Castro‐Vasconcelos, Gustavo Creazzo, Helena Cristina de Assis et autres

OBJECTIVE: Bioceramic sealers have been increasingly used in endodontics due to their favorable physicochemical and biological properties. However, evidence regarding the physicochemical properties, push-out bond strength, and adhesive interface characteristics of BioRoot Flow compared with other root canal sealers remains limited. Therefore, …
