Abstract

Background:  Provisional prosthesis must be cemented to the prepared tooth using a temporary cement. The effect of eugenol and eugenol free temporary cement on the transverse strength of provisional resins has not been completely clarified with evidence based information. Aim: This study compared the effect of eugenol and eugenol free cement on transverse strength of provisional restorative resins. Material and methods: Disks specimens were fabricated using metallic mould and glass plates. After being immerse at artificial saliva at 37 º C for 7 days , the specimens were fracture under 3 point loading in a universal strength machine at a crosshead speed of 0.75 mm/min. Maximal load to fracture in kilogram were recorded . Mean flexural strength were calculated in newton (n=10 group). Comparisons were made  using one -way - ANOVA f and Tukeys Post Hot Test ( P<0.001). Results: Mean transverse strengths ranged from 41.79 to 92.53 N. Heat cure acrylic with non eugenol cement(Accucem)has highest transverse strength and bis acrylic (Trantemp) with eugenol cement has least transverse strength. Conclusion: Within the limitations of this study, transverse strength of the heat cure acrylic with eugenol free cement is found to be highest.
