Rotary instruments in the treatment of chronic periodontitis: A randomized clinical trial
1Department of Periodontics and Implantology, Himachal Institute of Dental Sciences and Research, Paonta Sahib, Sirmour, India.
Background:
The study aimed at comparing the effectiveness of rotary instruments with hand instruments in non-surgical treatment of chronic periodontitis.
Materials And Methods:
Thirty-eight patients with chronic periodontitis, enrolled to this randomized, controlled clinical trial, were divided into two groups. Patients in the control group received scaling and root planing with hand instruments, whereas patients in the test group received treatment with rotary instruments. Clinical assessment by plaque index, bleeding on probing, probing depth, gingival recession, and clinical attachment level was made prior to and at 6 months after treatment. Differences in the clinical parameters were analyzed using the Wilcoxon signed rank test and Mann-Whitney U test.
Results:
Both treatments resulted in a significant improvement in all clinical recordings, but no differences in any of the investigated parameters were observed at baseline between the two groups.
Conclusion:
Non-surgical periodontal therapy with the tested rotary instruments may lead to clinical improvements comparable to those obtained with conventional hand instruments.
