Effects of Three Canal Sealers on Bond Strength of a Fiber Post

Effect of gutta-percha solvents on fiberglass post bond strength to root canal dentin

“…The negative effects on bond strength of several chemical agents used during root canal treatment, including endodontic irrigants (sodium hypochlorite, EDTA, and hydrogen peroxide), calcium hydroxide and eugenol of medicaments and sealers, have been well-documented (2,(19)(20)(21)(22)(23). However, few studies have assessed the influence of gutta-percha solvents on the bonding process itself (10,32).…”

“…These solvents may modify the chemical constitution of the dentin surface and affect its interaction with the restorative and root filling materials (18). The effects of several chemical agents used during endodontic therapy on the bond strength of fiberglass posts to root canal dentin have been studied (2,(19)(20)(21)(22)(23). However, studies addressing the fiberglass post bond strength to root canal dentin after root canal retreatment procedures are lacking.…”

Effect of Chlorhexidine and Ethanol on the Durability of the Adhesion of the Fiber Post Relined with Resin Composite to the Root Canal

“…The influence of auxiliary chemical substances and root canal sealers was the aim of other studies (33,34). In addition, the use of a fiber post relined with resin composite can also contribute to a more accurate assessment of adhesive procedures because after the adequate post adjustment to the root canal the cement layer thickness becomes smaller.…”

Effects of Different Curing Units and Luting Agents on Push-out Bond Strength of Translucent Posts

“…The FRC Postec post used in the present study has elasticity similar to dentin and is translucent, radiopaque, and designed to be tapered for better preservation of tooth structure (11,12). In the present study a Peeso reamer was used to remove the coronal part of root filling and the reamer of this post system (FRC Postec Plus reamer) was used to prepare the canal dentin according to the manufacturer's suggestions to achieve optimal matching between the post and root canal walls.…”
