Controlled clinical evaluation of the subpedicle connective tissue graft for the coverage of gingival recession.

The purpose of this study was to clinically evaluate the 1-year coverage of gingival recessions by a subpedicle connective tissue graft according to the original technique compared to untreated recessions by measuring probing sulcus depth (PSD), height of keratinized tissue (HKT), and mucogingival junction location changes. Paired gingival recessions were selected in 15 patients. In each patient, one recession was randomly assigned for treatment (test group) and the other recession was left untreated (control group) for 1 year.

Cryopreserved cancellous bone allograft in periodontal intraosseous defects.

The purpose of this study was to evaluate the potential of cryopreserved cancellous bone allograft (CCBA) in the treatment of intraosseous periodontal defects compared to surgical debridement alone (DEBR). Cancellous bone was procured from femur heads that had been extracted for hip prosthesis procedures and cryopreserved in liquid nitrogen (-196 degrees C) in a tissue bank. Ten patients without systemic disorders and advanced periodontal disease (at least 2 intraosseous defects) participated in this investigation.

New developments in synthetic bone replacement materials.

Synthetic bone replacement materials continue to be much discussed in the current periodontal literature. Numerous reports have shown their clinical use in the treatment of intraosseous defects. Periodontal treatment aims also include regeneration of a new functional attachment.

Histologic case reports of coralline hydroxyapatite grafts placed in human intraosseous lesions: results 6 to 36 months postimplantation.

Four intrabony lesions from four patients were studied. Presurgical measurements included clinical attachment level, degree of recession, probing pocket depth, Plaque Index, Gingival Index, and Sulcular Bleeding Index. These measurements were also taken at 6-month intervals after surgery.

[Clinical and histological evaluation of implantation of a microporous resin in periodontitis. Report of a case after 13 months].

A patient with adult periodontitis was treated for a 2 and 3-walled intrabony lesion on tooth n degrees 27. After scaling and root planing, the defect was surgically exposed and filled with a micro-porous resin. Following healing, there was a reduction in pocket depth as a result of gingival recession and a gain in probing attachment levels.

[Clinical evaluation of natural coral implantation in osseous periodontal defects. Results after one year].

17 intrabony periodontal defects on 14 patients were surgically treated by a alloplastic graft using micro-granules of natural coral. Criteria of evaluation were standardized probing and reproducible radiographs. The measures, made at day 0 and one year post-implantation showed a reduction in probing pocket depth (4.
