AIM The aim of this study was to investigate the influence of platelet-rich fibrin (PRF) on early wound healing and preservation of the alveolar ridge shape following tooth extraction. METHODS In this clinical trial, 20 symmetrical, premolar extraction sockets using split-mouth design were randomly selected with PRF or blood clot. The evaluations of wound(More)
Bone morphogenetic proteins (BMPs) are growth and differentiation factors that have been purified and widely accepted to be the most important regulators in the processes of bone formation. The aim of this study was to identify the BMPs that are expressed in normal human bone, and to investigate the specific pattern of BMP2-BMP9 expression in normal human(More)
Fabrication of polycaprolactone (PCL)-chitosan (CS) three-dimensional (3D) scaffolds using the novel technique of melt stretching and multilayer deposition was introduced. In brief, firstly, the PCL-CS monofilaments containing 0% (pure PCL), 10%, 20% and 30% CS by weight were fabricated by melting and stretching processes. Secondly, the desired multilayer(More)
AIM To investigate the biomechanical properties of poly ε-caprolactone (PCL)-chitosan (CS) scaffolds fabricated by the melt stretching and multilayer deposition technique. METHODS The PCL-CS scaffolds containing CS at 0% (pure PCL), 10%, and 20% by weight were prepared. For the monolayer scaffolds, shear and blending tests simulating the reconstruction of(More)
This study aimed to evaluate in vitro biocompatibility of a composite of nanoscale biphasic calcium phosphate (BCP) and collagen (C) compared to pure BCP (P) in different composition ratios of nanohydroxyapatite to nano-β-tricalcium phosphate (HA/β-TCP). Each study group comprised of three ratios of BCP (30/70, 40/60, and 50/50). For evaluation of cellular(More)
The biphasic calcium phosphate (BCP) concept was introduced to overcome disadvantages of single phase biomaterials. Different composition ratios of BCP bioceramics have been studied, yet controversies regarding the effects of ratio on biomaterial behavior still exist. In this study, BCP scaffolds were prepared from nano hydroxyapatite (HA) and β-tricalcium(More)
This study assesses the effect of low intensity pulsed ultrasound (LIPUS) on new bone formation during mandibular distraction osteogenesis (DO) in rabbits. 24 rabbits underwent DO on the right side of the mandible. 12 rabbits received a daily 20-min LIPUS (1.5 MHz, 30 mW/cm2) treatment on the first day of the distraction until they were killed at week 0(More)
PURPOSE This study aimed to evaluate the effect of biphasic calcium phosphate (BCP) with high hydroxyapatite/tricalcium phosphate (HA/TCP) ratios on bone formation in rabbit calvarial defects. MATERIALS AND METHODS Sixteen New Zealand white rabbits were randomly divided into two groups, a control group and an experimental group. In each animal, bilateral(More)
The ability to repair bone defects of polycaprolactone-chitosan scaffolds containing 20% chitosan (PCL-20%CS) fabricated using the melt stretching and multilayer deposition (MSMD) technique was assessed and compared with commercial scaffolds. Two calvarium defects of 11 mm in diameter were created in each of the fifteen New Zealand white rabbits. The(More)
AIM The aim of the present study was to investigate the temporal and spatial gene expression of bone morphogenetic proteins (BMP)-2, -4, and -7, and transforming growth factor-β (TGF-β), during the distraction process of the rabbit mandible. METHODS Twenty rabbits each had an osteotomy on the left mandibular body, and distraction devices were fixed. After(More)
