Abstract

Background:  This study was undertaken to evaluate and compare the abrasion resistance and microhardness of the following artificial acrylic teeth Cavitax (india), Ivostar (Ivaclar, vivodent, Liechtenslein, USA),Acryplus (Ruthinum,Italy)  Materials & Method: The Present study is an in-vitro study conducted to evaluate and compare the Abrasion Resistance and Microhardness of six different types of commercially available Artificial Acrylic teeth (Cavitax, Ivostar, Acryplus). 12 samples of each brand were evaluated for Abrasion Resistance employing Taber abrader testing Machine and for Microhardness Vickers hardness tester was used. After statistical Analysis MannWhitney U test.  Results:  Mean ± SD of abrasion resistance in Cavitax, Ivostar, Acryplus, groups were 0.003 ± 0.001, 0.005 ± 0.001, 0.008 ± 0.001respectively. Mean ± SD of microhardness in Cavitax, Ivostar, Acryplus groups were 19.68 ± 1.91 VHN, 30.95 ± 1.37 VHN, 39.15 ± 1.15 VHN, respectively. Conclusion:  Group 3(Acryplus) showed maximum Abrasion Resistance & maximum Microhardness.   Conclusion: It was found that all of the samples tested Group 3(Acryplus) had the maximum surface Abrasion Resistance and Microhardness value.
