<strong>Effect of Green Tea Extract Antioxidant on Dentin Shear Bond Strength and Resin-Tag Penetration Depth after Non-vital Bleaching</strong> <br> This study aimed to evaluate the effect of 10% and 35% green tea (10% and 35% GT) extract as an antioxidant after 2 minutes of application on dentin shear bond strength and resin tags penetration depth after non-vital bleaching. This research was conducted at the Chemistry Laboratory, Faculty of Medicine, University of Indonesia, and the Dental Materials Research and Development Laboratory, Faculty of Dentistry, University of Indonesia, in March-April 2022. <br> This study was approved by the Ethics Committee (10/Ethical Approval/FKGUI/III/2022; 09/Ethical Exempted/FKGUI/IV/2022) and conducted in accordance with the Declaration of Helsinki. <br> The shear bond strength assessment was done using a Universal Testing Machine with a 0.5 mm/minute cross-head speed. Confocal Laser Scanning Microscopy (CLSM) with a wavelength of 560 nm and a lens magnification of 40x was used to analyze the resin tag penetration by the fluorescence glow of rhodamine B.
