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.


Nonsignificant differences were found at 12 weeks follow up for all the parameters between test and control groups.


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.
