Clinical Trial Summary

Minimally invasive non-surgical therapy (MINST) is a new approach towards regeneration of deep periodontal defects. Important part of MINST procedure, besides usage of magnification loupes and piezo-electric devices seems to be the usage of special mini-curettes, originally mini-five and after mini-five of Hu-Friedy. So far only descriptive data about the clinical effects of such procedure are available and comparative studies that would include other treatment alternatives are lacking. Therefore, the aim of our study is, on split-mouth model, to compare the number of diseased sites (defined by probing depth ˃ 4 mm and bleeding on probing) after conventional non-surgical therapy and MINST with the usage of special mini-curettes. In addition, new 3D parameters obtained from 3D optical scanning will be developed for evaluation of volume changes of soft tissues.

Related Conditions & MeSH terms

• Periodontal Diseases
• Periodontitis

Intervention

Procedure:
• MINST
For reducing the need of surgical treatment in patients with chronic periodontal disease, we will use specifically designed Hu-Friedy curettes "mini five", "micro mini five" and "after five" together with piezoelectric device with thin and delicate tips that produce less periodontal trauma than usual Gracey curettes.
• Conventional SRP
Scaling and root planing with conventional instruments.
