Abstract:AimTo investigate the influence of pulse energy, tip geometry and tip position in simulated 3D‐printed root canals with multiple side canals at different levels in all directions on the cleaning performance of laser‐activated irrigation (LAI) compared to sonic activation (EDDY) and conventional needle irrigation (NI).Methodology3D‐printed root canal models (25/.06, length 20 mm, curvature 60°, radius 5 mm) with side canals (diameter 0.2 mm) at 2, 5 and 8 mm from the apex were filled with coloured biofilm‐mimic… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
