Department of Oral and Maxillofacial Surgery Posters

Obstructive sleep apnea (OSA) is a well-recognized disease entity affecting approximately 2% to 4% of the population. Maxillomandibular advancement (MMA) surgery is a highly successful surgical alternative to poorly tolerated CPAP therapy and achieves a success rate of 89% in the current literature. Our present study evaluates the effectiveness of MMA surgery in the treatment of patients with moderate to severe OSA based on Shers criteria of 50% reduction in AHI and AHI < 20. Radiographic and clinical treatment variables were evaluated in determining predictors of success for MMA in individuals with OSA.

Kallikrein-Related Peptidases Are Dysregulated In Pleomorphic Adenoma, Matthew D. Morrison 2018 The University of Western Ontario

Kallikrein-Related Peptidases Are Dysregulated In Pleomorphic Adenoma, Matthew D. Morrison

Electronic Thesis and Dissertation Repository

Objectives: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. Kallikrein-related peptidases (KLKs) have been identified as biomarkers in many human tumors and may influence tumor behavior. We investigated KLK1-15 messenger ribonucleic acid (mRNA) and proteins in PA specimens to determine a KLK expression profile for this tumor.

Methods: Fresh frozen PA tissue specimens (n = 26) and matched controls were subjected to RT-qPCR to detect KLK1-15 mRNA. Expression of KLK1, KLK12, KLK13 and KLK8 proteins were then evaluated via immunostaining techniques. Statistical analyses were performed with the level of significance set at P < .05.

Results: We observed downregulation of ...


Authentic Leadership In Illness Blogs: What We Can Learn From Jaw Surgery Bloggers, Marilyn Mitchell 2018 Bond University

Authentic Leadership In Illness Blogs: What We Can Learn From Jaw Surgery Bloggers, Marilyn Mitchell

Marilyn Mitchell

This paper argues that authentic leadership theory provides a useful model for explaining the communication of orthognathic or jaw surgery bloggers. Previous studies concluded that illness blogs can empower patients, but no research considered any leadership theory as a model for blogging. For this study, 24 publicly available blogs were analyzed to find expressions that demonstrated each of the four components of authentic leadership, which are self-awareness, relational transparency, communication based upon an internalized moral perspective, and balanced processing of information. The research also analyzed blog comments to find expressions that demonstrated followers’ development of the positive psychological capacities of ...

Mesenchymal Stem Cell (Msc) Spheroid Constructs Containing Microfluidic Bmp2-Plga Microcapsules In Bone Tissue Engineering., Bhavendrasinh Sayania

Dental Theses

Recombinant human bone morphogenetic protein-2 (rhBMP-2) is a clinically available osteogenic growth factor. In its current form, approved for clinical use, however, the growth factor is delivered in excessively high doses, resulting in unpredictable bone growth and unwanted clinical side effects. In this study, we evaluated a novel system, slow-release hybrid delivery system for PLGA- rhBMP-2 microcapusles in combination with BM MSC spheroids, and assess if it can lead to improved BMP-derived bone formation. The first aim of this study is to evaluate the osteogenicity of 3D cell spheroids as compared to 2D cultured cells, as we used primary cells ...

Articles

Objectives: The purpose of this literature review is to provide information on the different available techniques for implant-supported prosthetic retention, which are bar-clip, o-ring or magnets. Through presenting the practitioner preferences reported in literature, although limited from strict comparison due to the heterogeneity of methodologies and studied individuals, this review aims to identify the choices for maxillofacial prosthesis implant retention systems, regarding patient comfort and good aesthetic outcome, as an aid to surgical and prosthetic planning for implant-supported extraoral maxillofacial prosthetics. With proper knowledge of each implant retention system, a practitioner can design a treatment plan which allows for a ...


Expression Of Human Tissue Kallikreins (Klks) In Polymorphous Low Grade Adenocarcinoma (Plga), Jacqueline M. Cox 2017 The University of Western Ontario

Expression Of Human Tissue Kallikreins (Klks) In Polymorphous Low Grade Adenocarcinoma (Plga), Jacqueline M. Cox

Electronic Thesis and Dissertation Repository

Polymorphous low grade adenocarcinoma (PLGA) is the second most common malignant salivary gland tumour of the minor salivary glands. Human tissue kallikreins (KLKs) are a family of highly conserved serine proteases expressed by various tissues throughout the body. KLKs have become powerful tumour markers for the diagnosis of the cancer patient (e.g. PSA (KLK3)). The literature demonstrates a link between KLKs and salivary gland neoplasms. The purpose of this study is to determine levels of KLK mRNA in tissue samples of formalin fixed paraffin embedded polymorphous low grade adenocarcinoma (PLGA). Secondly, we wish to determine if KLK expression is ...
