Rotary Instrument in Non-Surgical Treatment of Chronic Periodontal Disease: Clinic Randomized Study

Abstract

Objective: The aim of this study is to compare the efficacy of rotary instruments vs hand scalers in non-surgical periodontal therapy, studying the variation of periodontal health indexes. Materials and Methods: Forty patients (age between 30 and 70 years) with advanced chronic periodontitis, that were recruited for the study, were divided into two groups; control group and test group. Control patients were treated with hand scalers while test group patients were treated with rotary instruments. Periodontal indexes were evaluated at baseline and after 3 months. Results: Nonsignificant differences were found at 12 weeks follow up for all the parameters between test and control groups. Conclusions: Within their limits, the results indicate that different instruments can be effective in removing calculus and endotoxins. This requisite is mandatory for a proper periodontal healing. The reasons for clinicians to use diamond-coated instruments are related to a faster procedure, and the clinical evidence of a smooth root surface. The clinicians' ability remains one of the most important variables that could affect periodontal therapy.
