Fatigue behaviour of root filled teeth: The role of endodontic sealers and restorative techniques

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This in vitro study aimed to evaluate the fatigue behaviour of root canal treated teeth, filled with either AH Plus Jet (AHP) or AH Plus Bioceramic Sealer (AHPB) and rehabilitated with either mesio‐occlusal‐distal (MOD) restorations (direct resin composite) or endocrowns (indirect resin composite).

Physicochemical and remineralisation properties of calcium silicate and glass ionomer cements applied in simulated caries‐affected dentine

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Calcium silicate‐based and glass ionomer cements are often used in caries‐affected dentine. This study investigated the remineralising and physicochemical properties of two calcium silicates and a glass ionomer cement. Human molars with Class I cavities were subjected to pH cycling to simulate caries lesions.

Excluding Ascites From the GEMA-Na Score Does Not Impact Outcome Predictions in Liver Transplant Candidates. [PDF]

open access: yesLiver Int
ABSTRACT Background and Aims Although GEMA‐Na outperforms MELD 3.0 for liver allocation, concerns about the subjectivity of its ascites component persist. We compared the performance of a GEMA‐Na iteration that excludes ascites with other allocation scores.
