AIMS: Several materials have been introduced as bone grafts, i.e., autografts, allograft, xenografts, and alloplastic grafts, and studies have shown them to produce greater clinical bone defect fill than open flap debridement alone. The aim of this clinical and radiological 6-month study was to compare and evaluate the clinical outcome of deep intraosseous defects following reconstructive surgery with the use of mineralized cancellous bone allograft (Puros(®)) or autogenous bone. MATERIALS AND METHODS: Ten patients with 12 sites exhibiting signs of moderate generalized chronic periodontitis were enrolled in the study...

Presurgical evaluation with cone beam computed tomography (CBCT) or computed tomography (CT) has become an essential tool for diagnosis and surgical planning, including maxillary sinus floor elevation. Before performing a sinus lift, the clinician's attention should not be only directed to the patency of the ostium through CBCT or CT, because many anatomical features could influence the surgical approach of sinus floor elevation. The goal of this article was to facilitate the communication between clinicians regarding the type of maxillary sinus, encourage in-depth analysis prior to surgery and reduce the risk of complications due to possible underestimation of important parameters...

Mesenchymal stromal cells (MSCs) are multipotent cells that can give rise to different cell types of the mesodermal lineages. They are powerful sources for cell therapy in regenerative medicine as they can be isolated from various tissues, and can be expanded and induced to differentiate into multiple lineages. Recently, the umbilical cord has been suggested as an alternative source of MSCs. Although MSCs derived from the umbilical cord can be induced to differentiate into osteoblasts with a phenotypic similarity to that of bone marrow-derived MSCs, the differentiation ability is not consistent...

This article aims to describe a modification of the semilunar coronally advanced flap. A total of 12 systemically and periodontally healthy patients presenting Miller Class I gingival recession were treated with the modified semilunar coronally advanced flap technique described in this article. After 1 year of follow-up, the mean root coverage was 85.4% ± 24.7%. Significant gingival recession reduction, clinical attachment gain, and reduction in dentin sensitivity was observed 1 year after surgery. This novel semilunar coronally advanced flap technique was demonstrated to be effective for root coverage in Miller Class I gingival recessions...

Current treatment of periodontitis is still associated with a high degree of variability in clinical outcomes. Recent advances in regenerative medicine by mesenchymal cells, including adipose stromal cells (ASC) have paved the way to improved periodontal regeneration (PD) but little is known about the biological processes involved. Here, we aimed to use syngeneic ASCs for periodontal regeneration in a new, relevant, bacteria-induced periodontitis model in mice. Periodontal defects were induced in female C57BL6/J mice by oral gavage with periodontal pathogens...

INTRODUCTION: The use of intermaxillary fixation (IMF) in the treatment of faciomaxillary fractures is the key factor for reduction and immobilization. Various techniques of IMF have been described in the past and recently IMF screws have been introduced. This technique has various advantages, including ease of use, less time consumption, less trauma to the surrounding soft tissues, and relatively reduced risk of needle stick injury. This study evaluates the efficacy of IMF screws over arch bar IMF before definitive fixation of facial fractures...

PURPOSE: Collagen barrier membranes were first introduced to regenerative periodontal and oral surgery to prevent fast ingrowing soft tissues (ie, epithelium and connective tissue) into the defect space. More recent attempts have aimed at combining collagen membranes with various biologics/growth factors to speed up the healing process and improve the quality of regenerated tissues. Recently, a new formulation of enamel matrix derivative in a liquid carrier system (Osteogain) has demonstrated improved physico-chemical properties for the adsorption of enamel matrix derivative to facilitate protein adsorption to biomaterials...
