Authors: Dr. Alisha Panjwani et al. Introduction: Air-powder polishing devices are increasingly used for stain and plaque removal. However, besides cleaning the tooth surface, they may increase the surface roughness of the dental tissues. This in turn may result in plaque accumulation and superficial degradation.
Thus the aim of this study was to assess the influence of three different abrasive agents: Pumice, Sodium bicarbonate and Calcium carbonate on the root surfaces using surface roughness tester & scanning electron microscopy (SEM). Material and Methods: Thirty extracted teeth were scaled and root planed, stored in saline and embedded in acrylic resin. Baseline values for surface roughness for root surface and implants were taken using a surface roughness tester. The samples were then randomly divided into three groups of ten each: Group I were treated using pumice with a rotating…
