TITLE:

"Light conductive fiber post: tecnology to improve microhardness and bond strength"

KEY WORDS:

"fiber post, bond strength, Vickers microhardness"

SUMMARY:

"This study evaluated two mechanical properties in the different thirds of two types of fiber post (FP). For the study, 50 extracted bovine teeth were used, which were divided between tests: Vickers microhardness (n=5) and push-out bond strength (n=20). The groups were named Commercial (Exacto post – Angelus, Londrina – PR, BR) and Experimental (glass and quartz fiber post patented) for both types of tests. The statistical evaluation of normality was performed using the Shapiro Wilk test, followed by Anova two-way test for comparing the variables, with a significance level of 0.05. The result obtained indicated that there was a statistically significant difference in bond strength between the same thirds of different FP. The commercial group obtained an average value of 4.07 MPa of bond strength on the apical third, while the experimental group presented an average of 8.02 MPa. Differentially, Vickers microhardness did not show this behavior. Thus, highest bond strength values in the most distant third from the crown were obtained in specimens in which glass and quartz fiber post was used."
