Aim: The aim of this study is to assess microleakage of three root canal filling materials using a dye penetration method under stereomicroscope. Background: C-Pointis a self-sealing obturation technology that relies on naturally occurring dentinal moisture to radially expand and adapt to irregular canal spaces. Methodology:A total of 30 extracted human single-rooted teeth were selected; the working length was determined by subtracting 1mm from the total length of the root. The chemo-mechanical preparation were completed up to size 30/0.06% taper using rotary system (Protaper next). Each canal were irrigated with 1% Sodium Hypochlorite with a 27 gauge needle and 17% EDTA. The prepared teeth were divided into 3 groups of 10 teeth each for obturation. Group 1=Teeth obturated by gutta percha using ah plus sealer, group 2= Teeth obturated by Guttaflow system, group 3=Teeth obturated by c-point with bio-ceramic sealer. The teeth were subsequently sealed and stored in methylene blue dye solution for 48 hrs. They were then sectioned to evaluate the linear apical leakage dye penetration using a stereomicroscope.
