Burs Versus Curettes in Root Planing.

This study compares the efficacy of diamond burs and Gracey curettes in non-surgical periodontal treatment of chronic periodontitis by clinical, microbiological, biochemical parameters and scanning electron microscopic investigations on root surfaces. Two quadrants of each of the 12 patients were treated with diamond burs whereas other 2 quadrants were treated with Gracey curettes. Also 21 hopeless teeth received root planing either with diamond burs or curettes or no treatment at all and were then extracted for microscopic evaluations.
