AbstractAbstract- Introduction-Various methods of restoring pulpless teeth have been reported for more than 200 years. Pierre Fouchard in 1728 was first to describe the use of artificial crowns and posts. At that time post were fabricated with gold or silver, and held in the root canal space with a heat softened adhesive called “Mastic”. The artificial crowns used at that time were either made up of natural crowns or crowns made of Ivory.
Material and method-30 cylindrical acrylic resin blocks were made by acrylic resin. The post were embedded perpendicularly in the acrylic block so that post was above the resin block. Specimens were divided into 3 groups with three different surface treatment.
Result- the mean shear stress of samples with different surface treatment was calculated and the data were analyzed initially by using a one–way analysis of variance (ANOVA), and the subsequent multiple comparisons between the different surface treatment groups were performed using Tukey HSD test.
Conclusion:- Within the limitation of this In-vitro study, it was concluded that surface treatment with airborne particle abrasion and silanization with two component system resulted in significantly higher bond strength than other methods of surface treatment.
