abstract

objective: fiber-reinforced composite (frc) posts have recently become more popular for restoring endodontically treated teeth because of providing esthetics, better stress distribution and lower risk of root fracture. resistance against tensile forces dislodging the post from the root canal is a prerequisite for these posts. this study aimed to evaluate the tensile retention (strength) of intracanal glass fiber posts produced by three manufacturers.   methods: in this interventional study, the crowns of 30 sound human maxillary central incisors were cut at the cementoenamel junction and the roots were endodontically treated. post space was prepared to a length of 10mm and the specimens were divided into three groups of 10. htco, anthogyr and svenskposts were used in groups 1, 2 and 3, respectively. the posts were cemented with panavia f2 resin cement according to the manufacturer’s instructions. specimens were then immersed in water at 37°c for 30 days and were then subjected to 7500 thermal cycles between 5-55°c. intracanal tensile retention (strength) was measured at a crosshead speed of 0.5 mm/min. data were analyzed using one-way anova at p<0.05 level of significance.   results: the mean retention was 188.53 (15.43), 183.81 (16.37) and 192.19 (17.50) n in htco, anthogyr and svensk posts, respectively. statistical analyses showed no significant difference in this regard among groups (p=0.111).   conclusion: within the limitations of this study, retention of htco glass fiber posts in the root canals was similar to that of two other posts.

Comparative Evaluation of Fracture Resistance of Simulated Immature Teeth Restored with Glass Fiber Posts, Intracanal Composite Resin, and Experimental Dentine Posts

AIM The aim of this study was to compare the fracture resistance of simulated immature teeth restored with gutta-percha, glass fiber posts (GFP), experimental dentine posts (DP) or Intracanal composite Resin (ICR). MATERIALS AND METHODS Fifty maxillary canines were decoronated, standardized and enlarged until, number 5 Peeso reamers were allowed to simulate immature teeth. After placement of ...

Three-Year Follow Up of Customized Glass Fiber Esthetic Posts

Customized glass fiber posts that is well adjusted into the root canal and have mechanical properties similar to those of dentin may be a suitable treatment for severely compromised endodontically treated teeth. This article reports a 3-year follow up of severely damaged endodontically treated teeth restored with unidirectional fiber glass customized post and core system instead of a convention...

Mechanical properties of glass fiber-reinforced endodontic posts.

Five types of posts from three different manufacturers (RTD, France, Carbotech, France and Ivoclar-Vivadent, Liechenstein) were subjected to three-point bending tests in order to obtain fatigue results, flexural strength and modulus. Transverse and longitudinal polished sections were examined by scanning electron microscopy and evaluated by computer-assisted image analysis. Physical parameters,...

Evaluation of the flexural strength of carbon fiber-, quartz fiber-, and glass fiber-based posts.

This study investigated the flexural strength of eight fiber posts (one carbon fiber, one carbon/quartz fiber, one opaque quartz fiber, two translucent quartz fiber, and three glass fiber posts). Eighty fiber posts were used and divided into eight groups (n = 10): G1: C-POST (Bisco); G2: AESTHETI-POST (Bisco); G3: AESTHETI-PLUS (Bisco); G4: LIGHT-POST (Bisco); G5: D.T. LIGHT-POST (Bisco); G6: P...

Chemical cleaning agents and bonding to glass-fiber posts.

The influence of chemical cleaning agents on the bond strength between resin cement and glass-fiber posts was investigated. The treatments included 10% hydrofluoric acid, 35% phosphoric acid, 50% hydrogen peroxide, acetone, dichloromethane, ethanol, isopropanol, and tetrahydrofuran. Flat glass-fiber epoxy substrates were exposed to the cleaners for 60 s. Resin cement cylinders were formed on th...
