Fibromyalgia Syndrome: Considerations For Dental Hygienists, Amber Walters, Susan L. Tolle, Gayle M. Mccombs

Dental Hygiene Faculty Publications

PURPOSE: Fibromyalgia syndrome (FMS) is a neurosensory disorder characterized by widespread musculoskeletal pain. Typically persistent fatigue, depression, limb stiffness, non-refreshing sleep and cognitive deficiencies are also experienced. Oral symptoms and pain are common, requiring adaptations in patient management strategies and treatment interventions. Appropriate dental hygiene care of patients suffering with this disorder is contingent upon an understanding of disease epidemiology, pathophysiology, clinical characteristics, oral signs and symptoms, as well as treatment approaches. With this information dental hygienists will be better prepared to provide appropriate and effective treatment to patients with FMS.

Effect Of Autoclaving On Flexibility Of Four Different Nickel Titanium Files, Anushree Mehrotra

Master's Theses (2009 -)

Introduction: Nickel-titanium (NiTi) files, introduced over 2 decades ago, have the unique property of superelasticity, are more resistant to fracture and are more flexible than stainless steel files. Recent developments in NiTi include M wire and Controlled/Thermal Memory Technology resulting in files with claimed superior properties to conventional NiTi files. Manufacturers recommend sterilization of files prior to usage. These files may be subjected to further autoclaving if reused. The purpose of this study was to test the effect of multiple cycles of autoclaving on the flexibility of four brands of NiTi files and to evaluate differences between brands. Materials and …

Differential Scanning Calorimetric (Dsc) Study Of New And Sterilized Nickel-Titanium Rotary Endodontic Instruments, Michael Dyriw

Master's Theses (2009 -)

Introduction: Nickel-Titanium (NiTi) files have become popular in endodontic procedures compared to traditional stainless steel hand files owing to their increased flexibility which is especially advantageous in curved canals. Due to the associated costs, endodontic instruments are frequently re-used, which requires sterilization between uses. With the application of temperature NiTi has the ability to undergo phase transformations, altering the properties of the instruments. The purpose of this study was to investigate phase transformations of four brands of NiTi rotary endodontic instruments in the as-received condition and after multiple sterilization cycles under steam sterilization, using differential scanning calorimetry. Materials and Methods: …

The Purpose And Value For Students Of Pbl Groups For Learning, Vicki J. Skinner, Annette Braunack-Mayer, Tracey A. Winning

Interdisciplinary Journal of Problem-Based Learning

Groups are central to problem-based learning (PBL) and educational and professional outcomes relevant to clinical education. However, PBL groups in practice may differ from theoretical conceptions of groups. Therefore, this study explored students’ understandings of the purpose and value of PBL groups for their learning. We conducted a naturalistic study with novice (first-year) students at two dental schools (Australia, Ireland), using observation and interviews analyzed thematically. Students constructed PBL learning as individual knowledge gain, and group purpose as information gathering and exchange; few students acknowledged the learning potential of group processes. Group value depended on assessment and curriculum context. Findings …

Continual Cell Deformation Induced Via Attachment To Oriented Fibers Enhances Fibroblast Cell Migration, Sisi Qin, Vincent Ricotta, Marcia Simon, Richard A. F. Clark, Miriam Rafailovich

Department of Biomedical Engineering Faculty Publications

Fibroblast migration is critical to the wound healing process. In vivo, migration occurs on fibrillar substrates, and previous observations have shown that a significant time lag exists before the onset of granulation tissue. We therefore conducted a series of experiments to understand the impact of both fibrillar morphology and migration time. Substrate topography was first shown to have a profound influence. Fibroblasts preferentially attach to fibrillar surfaces, and orient their cytoplasm for maximal contact with the fiber edge. In the case of en-mass cell migration out of an agarose droplet, fibroblasts on flat surfaces emerged with an enhanced velocity, v …
