Abstract

The purpose of this in-vitro study was to evaluate and compare the surface roughness of IPS e.max Press lithium disilicate after air abrasion with silica and alumina particles. Thirty lithium disilicate specimens of dimensions 5×5×7 mm, were fabricated by heat pressing ingots. The specimens were divided into 3 groups (n=10). Group A consisted of untreated specimens, group B of specimens air abraded with 50 µm silica particles and group C of specimens air abraded with 110 µm alumina particles. Surface roughness of specimens were analyzed using Stereomicroscope and image software. One way ANOVA revealed that, the higher mean surface roughness was recorded in specimens treated with alumina particles. The difference in mean surface roughness among the groups was statistically significant (p<0.05).

Key-words : Silica, Alumina, Lithium Disilicate, Stereomicroscope, Surface Roughness.
