Introduction: Scaling and root planing is essential in periodontal treatment. Manual scaling and root planing can often be difficult and time consuming due to the complex and unfavorable root morphology. The development of power driven mechanical instruments have shown advantages. The ultimate objective of all root treatment procedure is to render the treated root surface biologically compatible with the host periodontal tissues. Precise study of the root surface can be performed only by means of SEM. This study was undertaken to evaluate the root surface changes following manual and ultrasonic instrumentation using SEM. Objective: To evaluate and compare the efficiency and effectiveness of root planing instruments namely, Gracey curette and micro ultrasonic insert on the root surface of periodontally involved teeth by SEM evaluation. Materials and Method: Fifty anterior teeth with comparable amounts of subgingival calculus and a probing depth of 5-10 mm and indicated for extraction were enrolled in the study. Ten teeth were considered as controls, 20 teeth were instrumented with micro ultrasonic insert for a time period of 2 minutes and 20 teeth were instrumented with Gracey curette for a time period of 5 minutes. The instrumented root surfaces were assessed for the amount of remaining calculus and roughness and loss of tooth substance using SEM. For statistical analysis, the collected data were entered into the computer data base and analyzed using SPSS. Result: The difference in the amount of remaining calculus on the root surfaces instrumented with Gracey curette and Micro ultrasonic insert was negligible. Surface roughness and loss of tooth substance was slightly higher for root surfaces instrumented with micro ultrasonic insert compared to Gracey curette. Conclusion: Both Gracey curette and micro ultrasonic insert were effective in achieving adequate root debridement. The difference in the amount of remaining calculus and roughness and loss of tooth substance was not statistically significant between the root surfaces instrumented with Micro ultrasonic insert and Gracey curette. |
