An in vitro comparative study of compressive resistance of endodontically treated teeth restored with adhered glass fiber posts using total and self etching techniques

ABSTRACT:Aim of study: This research aims to know the better technique (total etch and self etch) that achieve the higher compressive resistance for teeth restored with resin reinforced fiber glass posts affixed using those techniques. This research compares between these two techniques by using the test of compressive resistance and study the pattern of failure happening.Materials and Methods: The sample consisted of from 40 lower premolars, there crowns cutted horizontally 2 mm away from the cementoenamel junction and root canal endodontically treated, and then divided into 2 groups according to the adhesive cement used to lute the glass fiber posts which used to restore the teeth: Group A: posts luted with resin cement based on total etch technique Group B: posts luted with adhesive resin cement based on self etch technique.Then, cores built up of all the teeth from composite and teeth crowned with metal crowns cemented with zinc phosphate cement. Each specimen was secured in a universal load-testing machine. A compressive load was applied at 45º degree angle at a crosshead speed of 1 mm/min to the long axis of the tooth until fracture occurred. Compression resistance recorded for each sample, and the statistical study was conducted for the results of the test.
Results: The results of mechanical test indicated that there is no statistically significant differences in the average compressive resistance between two groups. Also there is no statistically significant differences in the frequencies place of failure between two groups. Conclusions: Compressive resistance of treated teeth restored with glass fiber posts doesn't affect when attached to two different adhesive techniques (Total etch and Self etch) using resin cement and adhesive resin cements. The pattern of failure in all samples is the preferred type and capable to restore and repair.
