Objective: A combination of self-etch and additional etch techniques as pre-cementation procedures for fiber post restoration was reported able to increase the bonding of adhesive material. This research aimed to determine the effects of different etching techniques on resin cement penetration into dentinal tubules.
Materials And Methods: Thirty-two endodontic treated premolars were prepared for 10 mm fiber posts and were divided into two groups (n = 16).
