Color Characterization Of Color Changing Orthodontic Adhesives, Megan Fried

Master's Theses (2009 -)

Objective:A popular product to facilitate removal of excess adhesive during bonding of orthodontic appliances is a color changing adhesive. Before polymerization, these materials are a bright color but upon curing, manufacturers claim they become translucent. After debonding, there is often resin embedded within the enamel, so the appearance of these materials after polymerization can affect the esthetics of a patient’s dentition. The purpose of this study was to analyze the color characteristics of various orthodontic color changing adhesives and determine if there is a significant difference in color changing capabilities and in translucency after polymerization between products. Methods:Grengloo and Blugloo …

Muc1 And Polarity Markers Inadl And Scrib Identify Salivary Ductal Cells, D Wu, P J Chapela, C M L Barrows, D A Harrington, D D Carson, R L Witt, N G Mohyuddin, S Pradhan-Bhatt, M C Farach-Carson

Faculty, Staff and Student Publications

Current treatments for xerostomia/dry mouth are palliative and largely ineffective. A permanent clinical resolution is being developed to correct hyposalivation using implanted hydrogel-encapsulated salivary human stem/progenitor cells (hS/PCs) to restore functional salivary components and increase salivary flow. Pluripotent epithelial cell populations derived from hS/PCs, representing a basal stem cell population in tissue, can differentiate along either secretory acinar or fluid-transporting ductal lineages. To develop tissue-engineered salivary gland replacement tissues, it is critical to reliably identify cells in tissue and as they enter these alternative lineages. The secreted protein α-amylase, the transcription factor MIST1, and aquaporin-5 are typical markers for acinar …
