Treatment of Gingival Recessions Associated with Noncarious Cervical Lesions Using Natural Inlays Before Coronally Advanced Flap Application: A Case Series.
Authors: Köseoğlu S, Savran L, Yaşa B Abstract Treatment of gingival recessions associated with noncarious cervical lesions (NCCL) can be a challenging clinical situation for clinicians. Both periodontal and restorative treatment can be necessary for this kind of defect. By using both digitally precise computer-aided design/computer-assisted manufacture (CAD/CAM) procedures and natural inlay (NI) material for restoration of defects before the coronally advanced flap (CAF) surgery, attachment of soft tissues on the root surface can be achieved successfully. Seven nonsmoking patients with NCCL associated with ...

Cryopreserved Umbilical Cord Allograft for Root Coverage of Gingival Recession Defects: A Case Series.
Authors: Ross B, Ross SB Abstract Gingival recession is a component of periodontal disease that leads to exposure of the root surface, root hypersensitivity, and esthetic concerns. Treatment of these cases is typically performed with autologous grafts harvested from the palate. However, this is associated with a second surgical site that increases surgical time and patient morbidity. A potential alternative is the use of cryopreserved umbilical-cord allografts, which are known to contain anti-inflammatory properties and have been used clinically by numerous medical specialties. In this observational series, three p...

Retrospective Analysis of the Outcome of Ridge Preservation with Anorganic Bovine Bone Mineral: Marginal Bone Level at Implants Placed Following Healing of Grafted Extraction Sockets.
The objective of this study was to investigate marginal bone level (MBL) changes as the primary outcome of implants placed following healing of extraction sockets treated with ridge preservation, compared to implants placed following unassisted healing. A total of 268 patients (contributing 572 implants) treated from April 2005 to March 2013 were included in this retrospective study. Following estimation of the overall success rate of implants placed in the practice, 129 patients (contributing 222 implants) met the inclusion and exclusion criteria to be further evaluated. Of these, 78 patients (contributing 105 implants) r...

Platelet-Rich Fibrin as a Grafting Material in Periapical Surgery: A Case Series.
Authors: Kulkarni MR, Mohan J, Bakshi PV Abstract Positive effects of platelet-rich fibrin (PRF) on soft tissue healing are well documented, but its role in hard-tissue healing remains contested. The present case series documents the use of PRF as the sole grafting material in periapical bone defects. PRF was prepared and condensed into the bone defects after debridement. The defects were then covered with a collagen membrane and wound closure was performed. In all three cases presented in this report, excellent bone fill was observed in the periapical defects. The observed benefit may be due to the role of fibrin ...
