Abstract

ABSTRACTIntroductionPorcelain has color-rendering and optical properties that simulate natural teeth; though these restorations are considered to be color stable, discoloration is one of the primary factors for failure of esthetic restorations.Aims and objectivesTo evaluate the surface roughness and color stability of three different restorative materials when exposed to tobacco extract, cigarette smoke, and carbonated beverage.Materials and methodsA total of 99 samples were fabricated, 33 samples in each restorative material. A total of 33 samples were subdivided such that 11 samples of the above-mentioned restorative materials were subjected to tobacco extract, the other 11 were exposed to cigarette smoke in an artificial chamber, and the remaining 11 were immersed in carbonated beverage for a period of 90 days with variant exposure times. The pretreatment values of 99 samples for color stability were recorded using spectrophotometer and those of degree of surface roughness were recorded using profilometer. Posttreatment values were recorded using the same instruments.ResultsThe IPS e.max, zirconia disks when subjected to tobacco extract and cigarette smoke (p > 0.05) had no significant differences found for color stability and surface roughness. All three materials when exposed to carbonated beverages, statistically significant values were obtained (p < 0.001). Among the three different restorative materials used, Vita VMK Master exhibited the maximum change in value of surface roughness (0.035818 μm).ConclusionAmong the three irritants used, smoke and tobacco extract did not affect color or degree of surface roughness for three restorative materials.Carbonated beverages, on the contrary, exhibited significant differences in color stability as well as surface roughness when measured pre- and postexposure for all the three restorative materials.However, among the three materials, feldspathic porcelain exhibited superior change in color and surface roughness when measured postexposure to irritants.How to cite this articlePrajapati AM, Sanyal PK, Guru R, Vaswani P, Tewary S, Sushma R.
