Differential Effects Of Extracellular Matrix Glycoproteins Fibronectin And Laminin-5 On Dental Pulp Stem Cell Phenotypes And Responsiveness, Hyungbin Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dental pulp stem cells (DPSCs) are mesenchymal stem cells (MSCs) with the potential to differentiate in a limited number of other tissue types. Some evidence has suggested the modulation of DPSC growth may be mediated, in part, by exogenous extracellular matrix (ECM) glycoproteins, including fibronectin (FN) and laminin-5 (LN5). Although preliminary research suggests that some ECM glycoproteins may work as functional biomaterials to modulate DPSC growth responses, the primary goal of this project is to determine the specific effects of FN and LN5 on DPSC growth and viability.Using an existing DPSC repository, n = 16 DPSC isolates were cultured and …

Impact Of Financial And Demographic Factors On Severity Of Treatment Procedure, Vanessa Gunderson

Theses/Capstones/Creative Projects

Indirect pulp caps (IPCs) and pulpotomies are forms of vital pulp therapy. These procedures are performed on young patients who have deep cavities due to bacterial biofilm damage; however, the two are performed and utilized differently. The less severe of the two procedures is an IPC. This is when decayed dentin is covered with biocompatible material to avoid pulp exposure. The more severe procedure, the pulpotomy, is when the inflamed coronal pulp tissue is removed either partially or fully to save any remaining pulp tissue. In this study, all IPCs and pulpotomies performed by Dr. Ben Reimer throughout ~4.5-years of …

Management Of Pulpal Floor Perforation Using Biodentine™: Case Report, Chaima Bouhajja, Mayada Jemâa, Mohamed Bassem Khattech

International Arab Journal of Dentistry

During endodontic treatment in multi-rooted teeth, furcation perforation refers to an opening in the pulpal floor, leading to a communication with the periodontal ligament space. A three-dimensional hermetic seal, with a biocompatible material, is a key point for the success of pulp floor perforation repair. MTA® has been considered, for a long time, as a gold standard in furcation perforation repair. Besides, BiodentineTM, when used for the same purpose, showed considerable performance and good results. The purpose of this paper was to report the management of an iatrogenic perforation of pulpal floor in the maxillary right first molar, using BiodentineTM.
