- Abstract
The objective of this study is to evaluate the bond strength of glass fiber post af-ter cemented with RelyX?"? Unicem resin cement under different barometric pres-sure conditions. A total of 20 extracted, single-rooted lower premolars were endo-dontically treated. Post space was prepared and the glass fiber post was cemented with RelyX?"? Unicem resin cement. They were then randomly divided into two subgroups (n=10) which were normal atmospheric pressure condition and hyper-baric pressure condition (higher than normal atmospheric pressure). The pull-out bond strength of glass fiber post was tested using a universal testing machine. In-dependent t-test was used in the analysis. The mean pull-out bond strength of Re-lyX?"? Unicem resin cement in hyperbaric pressure condition, 245.8 (±46.3) N ex-hibited significant higher (p>0.05) than when compared to normal atmospheric pressure condition, 148.5 (±35.0). The bond strength of glass fiber post was influ-enced by different barometric pressure conditions. RelyX?"? Unicem resin cement had a higher bond strength under hyperbaric pressure condition than normal at-mospheric pressure condition.
