Introduction: The demand for esthetic dental treatments is increasing in recent years mainly due to improved oral hygiene and better maintenance of health teeth older individuals. Bleaching discolored anterior the most popular among treatments. Even individuals with sound adequate esthetics seek have whiter region. aim this study was evaluate tooth color changes following conventional in-office bleaching techniques compared light-activated methods using different light sources.Methods:...
Abstract Magnesium (Mg) plays an important role in controlling bone apatite structure and density is a potential bioactive material repairing critical‐sized defects. In this study, we aimed to evaluate the effect of adding NanoMgO polycaprolactone/beta‐tricalcium phosphate (PCL/β‐TCP) scaffolds on regeneration. Novel 3D‐printed porous PCL/β‐TCP composite containing 10% nanoMgO were fabricated by fused deposition modeling (FDM) compared with (1:1) (control). The morphology physicochemical...
Abstract To evaluate the impact of photobiomodulation therapy (PBMT) on injection pain perception and compare it with a topical oral anesthetic gel. A total 30 patients 6 to 9 years‐old seeking pulpotomy treatment maxillary secondary primary molars both sides were considered for this split‐mouth triple‐blind randomized clinical trial. On one side maxilla, low‐level laser (diode laser, 808 nm, 250 mW; 16.25 J; 32.5 J cm −2 ) was irradiated upon buccal gingiva tooth, while Benzocaine 20% gel...
Abstract Dynamic‐based systems are bio‐designed in order to mimic the micro‐environments of bone tissue. There is limited direct comparison between perfusion and perfusion‐rotation forces designing a bioreactor. Hence, current study, we aimed compare given bioreactors for regeneration. Two types including rotating & were designed. Mesenchymal stem cells derived from buccal fat pad loaded on gelatin/β‐Tricalcium phosphate scaffold. Cell‐scaffold constructs subjected different treatment...
Abstract In this study, we developed an injectable in situ forming hydrogel/microparticle system consisting of two drugs, melatonin and methylprednisolone, to investigate the capability for chondrogenesis vitro vivo. The chemical, mechanical, rheological properties were investigated. For evaluation, adipose‐derived stem cells might be mixed with hydrogel/microparticles, then cellular viability was analyzed by acridine orange/propidium iodide 4′,6‐diamidino‐2‐phenylindole staining also...
The use of cell‐free scaffolds containing bioactive molecules having a controlled released pattern has been proposed as promising approach in field tissue engineering. This system would eliminate the challenges associated with cell implantation. For bone engineering, particular, environment favor both de novo formation and vascularization are considered critical approach. Erythropoietin (EPO) shown to have bone‐related pleiotropic effects. However, due adverse systemic side effect, its local...
Abstract In vivo bioreactors serve as regenerative niches that improve vascularization and regeneration of bone grafts. This study has evaluated the masseter muscle a natural bioreactor for βTCP or PCL/βTCP scaffolds, in terms regeneration. The effect pedicle preservation, along with sole, MSC‐ rhBMP2‐combined application also been studied. Twenty‐four mongrel dogs were randomly placed six groups, including βTCP, βTCP/rhBMP2, βTCP/MSCs, PCL/βTCP, PCL/βTCP/rhBMP2, PCL/βTCP/MSCs. During first...
Extracellular matrix (ECM)-contained grafts can be achieved by decellularization of native bones or synthetic scaffolds. Limitations associated with harvesting the bone has raised interest in preparing vitro ECM bioscaffold for tissue engineering. Here, we intend to develop an ECM-contained construct via decellularizing engineered gelatin-coated β-tricalcium phosphate (gTCP) scaffold. In order find optimal protocol cell-loaded gTCP scaffolds, they were seeded buccal fat pad-derived stem...
Bioreactor system has been used in bone tissue engineering order to simulate dynamic nature of environments. Perfusion bioreactors have reported as the most efficient types shear-loading bioreactor. Also, combination forces, such rotation plus perfusion, enhance cell growth and osteogenic differentiation. Mathematical modeling using sophisticated infrastructure processes could be helpful streamline development functional grafts by estimating defining an effective range bioreactor settings...
The present study aimed to compare the effect of photobiomodulation with different energy densities on angiogenic differentiation human periodontal ligament stem cells (hPDLSCs) and from exfoliated deciduous teeth (SHED). Photobiomodulation therapy a 660 nm diode laser (2.4 J/cm
