Fracture resistance of endodontically treated teeth restored with glass fiber reinforced posts and cast gold post and cores cemented with three cements.
J Prosthet Dent. 2013 Aug; 110(2):127-33.JP

Abstract

STATEMENT OF PROBLEM

Dental fractures can occur in endodontically treated teeth restored with glass fiber reinforced posts and cast gold posts.

PURPOSE

The objective of this study was to record the fracture strength of endodontically treated teeth restored with glass fiber reinforced or cast gold post and cores cemented with 3 cements.

MATERIAL AND METHODS

Forty-two single-rooted premolars with standardized weakened roots were endodontically treated and allocated to 6 experimental groups (n=7) defined by the 2 factors investigated: post system and cement. Three groups were restored with glass fiber posts and resin-modified glass ionomer cement, dual-polymerizing resin cement, or chemically active autopolymerizing resin cement. The other 3 groups were restored with cast gold post and cores and the same 3 cements. The cores of the glass fiber post groups were fabricated with composite resin core material. Metal crowns were cemented on the cores in the 6 groups. The entire system was subjected to continuous compression in a universal testing machine, and fracture limit and location (cervical third, middle third, or apical third) were noted. Two-way ANOVA and the Scheffé test were used to analyze the data and compare the groups (α=.05).

RESULTS

Two-way ANOVA showed significant differences in the post type (P<.001) and the cements (P<.001). The interaction between them (P<.001) was statistically significant in the fracture resistance of the endodontically treated teeth. The greatest interaction between post and cement was the glass fiber post with resin-modified glass ionomer cement, followed by the cast gold post and core with resin-modified glass ionomer cement.

CONCLUSIONS

The use of a glass fiber reinforced post and resin-modified glass ionomer cement increased the fracture resistance of endodontically treated teeth.
