background: alveolar ridge preservation could be performed immediately following tooth extraction to limit dimensional changes of alveolar process due to bone resorption. the aim of this study was to compare the clinical and histologic outcomes of socket preservation using two different graft materials; deproteinized bovine bone mineral (dbbm) and demineralized freeze‑dried bone allograft (dfdb...

INTRODUCTION Metabolic complications are common after kidney transplantation and can cause considerable morbidity and even threaten graft function. This study aimed to investigate the prevalence of hyperlipidemia and its impact on graft function in 10 years of follow-up of patients undergoing kidney transplantation. MATERIALS AND METHODS This prospective study was conducted on 73 patients who...

PURPOSE This in vitro study determined the stress distribution around an implant placed in a posterior edentulous maxillary model with simulated sinus grafts that had different degrees of stiffness. MATERIALS AND METHODS The composite photoelastic model with a standard threaded implant consisted of simulated crestal cortical, cancellous, sinus cortical, and grafted bone. The graft maturation ...

context this study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. evidence acquisition english-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in ...

Background: To avoid the problems associated with harvesting autogenous donor graft bone, substitutes have been developed to act as an osteoconductive matrix and provide osteoinductive potential. The efficacy of any bone-graft material depends upon the presence of osteoblasts, or stem cells that can develop into osteoblasts, and cytokines and growth factors that regulate the bone-formational wo...

PURPOSE The aim of this study was to elucidate the effect of a bovine hydroxyapatite/collagen (BHC) block in one-wall intrabony periodontal defects in dogs. METHODS A one-wall intrabony periodontal defect (4 mm wide and 5 mm deep) was prepared bilaterally at the mesial side of the mandibular fourth premolar in five beagle dogs. After thorough root planing, block-type BHC (4×5×5 mm) was placed...

PURPOSE The aim of this randomized, controlled, blinded clinical study was to compare ridge dimensions and histologic characteristics of ridges preserved with 2 different graft materials. MATERIALS AND METHODS Twenty-four subjects, each requiring a nonmolar extraction and delayed implant placement, were randomly selected to receive ridge preservation treatment with either an allograft in an e...

Periodontal disease is categorized by the destruction of periodontal tissues. Over the years, there have been several clinical techniques and material options that been investigated for periodontal defect repair/regeneration. The development of improved biomaterials for periodontal tissue engineering has significantly improved the available treatment options and their clinical results. Bone rep...

For the synthesis of biocomposite materials for useful applications, it becomes necessary to modify the surface of natural fibers through chemical treatments. Morphology, structure and properties of natural fibers have an obvious effect on the mechanical properties of the biocomposite materials. It is thus necessary to know the morphology, thermal stability and crystalline behavior of original ...

UNLABELLED Alloplastic materials can be used together with tissue and structure to close nasal septal perforation. AIM to test cellulose use in the closure of septal perforation in rabbits and to compare fibrosis, inflammation, vascular congestion and graft integrity. MATERIALS AND METHODS Fifteen rabbits. The rabbits were divided into two groups: CONTROL Five rabbits and Bionext and fibr...
