Assessment Of Fracture Resistance Of Maxillary First Molars After Root Canal Preparation Using Three Different Rotary Instruments (V-Taper, Protaper, Vortex Blue): Finite Element Analysis, Mehran Malakpour

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Long term success of endodontically treated teeth has been one of the most challenging aspects of the field of endodontics due to reduced fracture resistance of these teeth. Recently, researchers have heightened focus on conservative endodontics in order to sustain the tooth integrity, and reduce factors impacting the fracture resistance of endodontically treated teeth. As a result, rotary instrument manufacturers have developed files that have a minimal effect on original root canal anatomy. This study used Finite Element Analysis to investigate the dental biomechanical effect of rotary instrumentation during root canal therapy. The aim of this study is to …

To Do Or Not To Do? Slow Orthodontic Extrusion For Implant Site Development In Esthetic Zone At The Anterior Maxilla, Hui-Chen Tsai, Chung-Chen Jane Yao, Cheing-Meei Liu

Taiwanese Journal of Orthodontics

Slow orthodontic extrusion (SOE) for implant site development, was introduced in 1991. It has been more than 20 years since this treatment was applied in our clinical practice. In this paper, we investigate surgeon's expectation of SOE for special requirements of immediate implantation by a clinical case. We also review case reports/case series searched from PubMed and inspect the power of evidence of these reports from the integration of data collection, and try to define the value of SOE. If the SOE cannot eliminate at least one surgical procedure, we need to consider the necessity of SOE before implant surgery.

A Comprehensive Diagnostic System For Orthodontists- Beyond Angle’S Classification, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

Traditionally orthodontists have used the classification system developed by Edward H. Angle in 1900 to describe the malocclusion of an orthodontic patient. This classification is very limited with respect to the information it provides and should be replaced by a more detailed and inclusive description of a patient’s malocclusion as well as the underlying biology. In this review article we propose a new technique that ensures all pertinent information gets considered and we suggest a systematic approach to a more differentiated orthodontic diagnosis. Our approach divides the diagnosis into clearly defined categories that bring together the clinical findings into a …

School of Dentistry Faculty Research and Publications

Ankylosing spondylitis (AS) is an inflammatory rheumatoid disease categorized within spondyloarthropathies (SpA) and manifested by chronic spinal arthritis. Several innate and adaptive immune cells and secreted-mediators have been indicated to play a role in AS pathogenesis. Considering the limitations of current therapeutic approaches (NSAIDs, glucocorticoids, DMARDs and biologic drugs), finding new treatments with fewer side effects and high therapeutic potentials are required in AS. Mesenchymal stem cells (MSCs) with considerable immunomodulatory and regenerative properties could be able to attenuate the inflammatory responses and help tissue repair by cell-to-cell contact and secretion of soluble factors. Moreover, MSCs do not express HLA-DR, …

Microfluidic Synthesis Of Plga/Carbon Quantum Dot Microspheres For Vascular Endothelial Growth Factor Delivery, Meisam Omidi, Mohadeseh Hashemi, Lobat Tayebi

School of Dentistry Faculty Research and Publications

In this study, vascular endothelial growth factor (VEGF) loaded poly(D,L-lactide-co-glycolide) (PLGA) – carbon quantum dot microspheres were produced using microfluidic platforms. The microcapsules were fabricated in flow-focusing geometry with a biphasic flow to generate solid/oil/water (s–o–w) droplets. To avoid any damage to protein functional and structural stability during the encapsulation process, the VEGF was PEGylated. The produced microspheres were intact and highly monodisperse in size (CV < 5%). Furthermore, microspheres in a size range of 16–36 µm were achieved by adjusting the flow ratio parameter. The encapsulation efficiency, release profile, and bioactivity of the produced microparticles were also studied. The loading efficiency of PEGylated VEGF in the microparticles was varied from 51–69% and more than 90% of PEGylated VEGF was released within 28 days. Furthermore, the release of VEGF was indirectly monitored by carbon quantum dots. The present monodisperse and controllable VEGF loaded microspheres with reproducible manner could be widely used in tissue engineering and therapeutic applications.
