Objective: the Purpose of this study was to evaluate in vitro the
apical microleakage of methacrylate risen-based sealer (EndoREZ )
after root canal irrigation with sodium hypochlorite or chlorhexidine
digluconate.
The aim of this study was to evaluate and compare the effect of irrigation
solutions on the dentin flexural strength .(20) extracted third molars were
gathered with age avarege (18-24) years old, and the dentine bars that will
be prepared and designed for study with similar dimensions (width 1
mm, thickness 2 mm, Length of at least 7 mm).
