A Method to Trace Porphyromonas gingivalis Within Periodontal Ligament in 3D
(2021-05-07)Background and Objective: Periodontitis is an inflammatory disease caused by bacterial dysbiosis that leads to tooth support loss and eventually, loss of tooth. There have been studies using micro-CT, histology, and electron ... -
A Novel Injectable Hydrogel Incorporating Lipoxin for Treatment of Inflammation-mediated Bone Resorption
(2021-07-19)Increased inflammation can disturb bone homeostasis leading to increased osteoclastogenesis and bone resorption. Studies have demonstrated that specialized pro-resolving lipid mediators such as lipoxins, can counteract ... -
Assessing the Neurotoxicity of Endodontic Sealers
(2021-08-12)Many times the relationship between dental materials and clinical outcomes is poorly understood because so little is known about the biocompatibility of materials and the biological pathways they may affect. In endodontics, ... -
Attenuation of the Progression of Articular Cartilage Degeneration by Inhibition of Tgf-β1 Signaling in a Mouse Model of Osteoarthritis
(2015-07-02)Background The goal of this study is to understand role of transforming growth factor beta 1 (TGF-β1) in development of osteoarthritis (OA). Results from studies indicate that the genetic inactivation of Smad-3, or the ... -
Biologic Significance of 5-Hydroxymethylcytosine Expression in Oral Mucosal Epithelial Dysplasia and Oral Squamous Cell Carcinoma
(2016-03-03)Current modeling postulates that the development of cancer is driven by the accumulation of genetic mutations and epigenetic modifications, resulting in a clonal population of cells with deregulated growth characteristics. ... -
Cellular Response to Expansion and Compression Forces in Mouse Midpalatal Suture and Surrounding Structures
(2016-08-16)Objectives – To investigate the anatomy of the mouse palate, the midpalatal suture, and the cellular characteristics in the sutures before and immediately after midpalatal suture expansion, and as well as, to study the ... -
A Comparison of Zirconia CAD/CAM to Conventionally Fabricated Single Implant Restorations in the Esthetic Zone
(2015-07-02)Objective: This project aimed to determine whether single tooth implant restorations fabricated with CAD/CAM zirconia abutments/porcelain fused to zirconia crowns reveal different biological and esthetic outcomes compared ... -
A Comprehensive Assessment of Soft Tissue Esthetics
(2015-07-02)This thesis investigated the efficacy of two techniques, digital spectrophotometry and narrow-band endoscopy, in observing and describing gingival tissue in a patient population. The efficacy of existing gingival restorative ... -
Comprehensive Optical Assessment of Peri-Implant Mucosa
(2015-07-02)Esthetic outcomes with implants begin with proper implant placement, but the predictability of the peri-implant esthetic outcome is also affected by patient’s pre-existing or reconstructed local tissue. An unpleasant optical ... -
Deletion of the Parathyroid Hormone Receptor in Marrow Adipose Lineage Precursors (MALPs) Prevents Their Negative Regulation of Skeletal Homeostasis
(2021-05-19)Background and objectives: Parathyroid hormone (PTH) is essential for skeletal homeostasis and PTH[1-34] (teriparatide) is used to treat severe osteoporosis, medication-related osteonecrosis of the jaws, and enhance implant ... -
Determination of Attitudes and Knowledge about Patient Perceptions of Expanded Roles and Responsibilities for Dentists as "Oral Physicians"
The overall objective of this study was to determine knowledge and attitudes of dentists and patients about dentists’ expanding their roles in preventive primary health care as oral physicians. There are hundreds of genetic ... -
Development of Novel Anti-DC-STAMP Monoclonal Antibody Targeting Osteolytic Periodontal Lesion
(2016-08-16)Background: Dendritic cell-specific transmembrane protein (DC-STAMP) plays a key role in the induction of osteoclast (OC) cell fusion. This conclusion is supported by evidence showing that osteoclast cell fusion is diminished, ... -
Electrokinetic Flow Assisted Dentin Disinfection
(2021-07-19)Background: The bacterial persistence within the root canals and dentinal tubules in infected and necrotic pulp poses a serious health risk, with reinfection of the endodontically treated tooth being one of the main problems ... -
Evaluation of αLphav Integrin Role in Mouse Model Induced Periapical Periodontitis
(2016-08-16)Abstract: Background: alphav (av) integrin is the most common integrin alpha subunit, it is expressed in different cells and involved in many cellular process including adhesion, migration, survival and growth factor ... -
Experimental Evaluation of Discoid Domain Receptor 2 as an Ideal Target for Development of Disease-Modifying Osteoarthritis Drugs
(2015-07-02)Abstract: Osteoarthritis (OA) affects 250 million people worldwide. Currently, no targets for disease-modifying osteoarthritis drugs exist. Matrix metalloproteinase-13 (MMP-13) would make it an ideal target; however, its ... -
Halofuginone Prevents the Progression of Osteoarthritis
(2015-07-02)Background: Halofuginone (HF) is a natural product that has been shown to have therapeutic benefits in a variety of pathologic conditions, from cancer to autoimmune diseases. These beneficial effects are mainly through ... -
Immune Reconstitution of B Cells Following Allogeneic Hematopoietic Cell Transplantation
(2015-07-02)Objectives: Graft versus host disease (GVHD), infections and disease relapse continue to be major complications of allogeneic hematopoietic cell transplantation (HCT). B cell abnormalities have been associated with these ... -
Immunomodulation of Macrophages in Periapical Wound Healing
(2016-08-16)Background: A periapical lesion is an infection-induced inflammation around the apex of the tooth caused by bacterial invasion and ultimately results in the destruction of bone in the area. To date, the relationship between ... -
Impact of Resolvin E1 on Experimental Periodontitis and Periodontal Biofilm
