Abstract The purpose of this study was to compare the effectiveness of an air‐powder abrasive technique to conventional root planing during periodontal surgery. 7 patients scheduled for multiple extractions of periodontally‐involved teeth were selected. Full thickness mucoperiosteal flaps were reflected, and proximal surfaces of 32 teeth were either ultrasonically scaled and exposed to the air‐powder abrasive, or ultrasonically scaled and then manually root planed. Following extraction, teeth were stained for residual plaque and photographed, or prepared for scanning electron microscopy. The air‐powder abrasive technique used for surgical root preparation was found to produce a root surface favorably comparable to manual root planing with regard to removal of plaque, calculus, and exposed cementum. A mean of 80 μm of cementum was abraded away after 40 s of exposure to the air‐powder spray. The air‐powder abrasive spray demonstrated an advantageous ability to remove plaque and cementum from areas of difficult access, such as furcations and root flutings.
