Efficacy of Passive Ultrasonic Activation Assisted Hand vs. Rotary Retreatment Files in the Removal of Root Canal Filling Material: An In Vitro Study [PDF]

Journal of Clinical and Diagnostic Research, 2020
Introduction: Endodontic treatment failures are caused by persistent or secondary intraradicular infection due to inefficient treatment or re-infection of the obturated root canal system because of coronal or apical leakage.

Effectiveness of supplementary protocols for filling material removal after sealer ultrasonic activation - a laboratory investigation [PDF]

Brazilian Oral Research
Ultrasonic activation of the endodontic sealer makes it difficult to remove the material during endodontic reintervention. Therefore, supplementary removal protocols should be tested to optimize the removal of the remaining filling material.

Quantitative microleakage analysis of root canal filling materials in single‐rooted canals

Scanning, 2015
SummaryThe purpose of this study was to analyze the sealing ability of different root canal filling materials over a 6‐week period using a glucose penetration model. Forty‐six recently extracted human premolars were used in this study. The root canals were enlarged to 40/0.06. Prepared canals were randomly assigned into four groups (n = 10) as follows:

Basroparib inhibits YAP‐driven cancers by stabilizing angiomotin

Molecular Oncology, EarlyView.
Basroparib, a selective tankyrase inhibitor, suppresses Wnt signaling and attenuates YAP‐driven oncogenic programs by stabilizing angiomotin. It promotes AMOT–YAP complex formation, enforces cytoplasmic YAP sequestration, inhibits YAP/TEAD transcription, and sensitizes YAP‐active cancers, including KRAS‐mutant colorectal cancer, to MEK inhibition.
