Periodontal Osseous Wall Piezosplitting and EDTA Root Surface Etching

A Novel Approach of Periodontal Osseous Wall Piezosplitting and EDTA Root Surface Etching in Management of Localized Intrabony Defects With Wide Angulation. Controlled Clinical Trial

This study was designed to investigate the use of minimally invasive Piezo knife to harvest vascularized interceptal bone pedicle in treating intrabony defects.

Sixteen non-smoking patients with severe chronic periodontitis participated in this prospective, randomized clinical study. Patients were randomly assigned into one of a 2 groups (8 patients each): bone substitute grafting of the intrabony defect, control group (Gr1), intrabony defect osseous wall swaging (OWS) combined xenograft (Gr2). In both groups root surfaces where treated with a neutral 24% EDTA gel and saline irrigation. Clinical and radiographic measurements were reassessed at 6 months after surgery.

Inclusion Criteria:

1. good compliance with plaque control instructions following initial therapy
2. teeth involved were all vital with no mobility ;
3. each subject contributed a single predominately 2 or 3-wall intrabony interproximal defect around premolar or molar teeth without furcation involvement;

Exclusion Criteria:

1. no systemic diseases which could influence the outcome of therapy;
2. absence of periodontal treatment during the previous year.
