Abstract :

<p> Ask the average person how they would most like to improve their smile and the answer would most often be “with whiter and ighter teeth.” It is commonly known that people are responded to in a more positive manner when they have a dazzling, healthy smile. The teeth may exhibit either extrinsic or intrinsic discolorationTo evaluate the effect of bleaching on color, morphology and surface roughness of enamel by using SEM, EDX and Profilometer. Analysis for surface roughness showed that there was statistically significant difference in roughness values of both the groups. The samples treated with H2O2 assisted with plasma showed lower mean roughness value (0.29) than the samples treated with H2O2 (0.83). From the observations of this in vitro study we conclude that using low temperature atmospheric pressure plasma could be supplementary to the conventional method of bleaching because combining the plasma jet and H2O2. It improved the bleaching efficacy in terms of whitening effect, with comparatively less morphological and compositional alterations in enamel.</p>
