EFFECT OF SALIVA CONTAMINATION DURING FIBER POST CEMENTATION ON MICROTENSILE BOND STRENGHT

The aim of this in vitro study was to evaluate effects of saliva contamination on microtensile bond strenght during cementation of glass fiber posts by using different adhesive materials. Thirty of one-rooted-teeth were used and divided into 6 groups (n=5). First group was cemented with using total etch adesive agent (3M Adper Single Bond), second group was cemented with using self etch adesive agent (3M Adper Prompt L-pop) and posts were cemented with dual cure resin cement. Third group was cemented by using self-etch self-adesive cement (Smart CEM Dentsply,). Forth group was cemented with using total etch adesive agent (3M Adper Single Bond), fifth group, self-etch system was contaminated with saliva and posts were cemented with dual cure resin cement. Sixth group, root canal was contaminated before self-adhesive cementation (Smart CEM Dentsply). Microtensile bond strenght tests were performed. Data were analized by Kruskall-Wallis variance analysis. Self-etch and total etch control groups (7.5 N/mm²) had showed the highest score (7.5 N/mm²) but self-adhesive control groups both contamination and control groups had showed the lowest rates (1.8 N/mm²).
