Survival Rates Of Primary Endodontic Therapy Following Core/Post And Crown Placement, Kandace Yee
Survival Rates Of Primary Endodontic Therapy Following Core/Post And Crown Placement, Kandace Yee
Master's Theses (2009 -)
Introduction: The objective of this study was to determine if a correlation exists between the time to core or post and core (core/post) placement following non-surgical root canal therapy (NS RCT), the time to crown placement following core/post placement, and the incidence of an untoward event. Materials and Methods: Utilizing the Delta Dental of Wisconsin Insurance Database, information was analyzed from 476,479 initial NS RCT procedures. Of these teeth, 160,040 had a core/post and a crown placed before the end of the continuous coverage period or occurrence of an untoward event. Untoward events were defined as having a retreatment, apicoectomy, …
Qmix 2in1 And Naoci Precipitate: Documentation, Identification, And Exothermic Reaction, Gordon L. Barkley Iii
Qmix 2in1 And Naoci Precipitate: Documentation, Identification, And Exothermic Reaction, Gordon L. Barkley Iii
Master's Theses (2009 -)
Introduction: The aim of this study was to document and identify precipitate formation and exothermic reaction caused when mixing NaOCl and QMiX. Methods: Photography captured time-dependent changes when mixing NaOCl and QMiX at; 0 seconds, 30 seconds, 1 minute, 30 minutes, 1 hour, and 24 hours. A differential scanning calorimeter (DSC) was utilized in determination of heat flow while analyzing temperature change (°C), enthalpy (mJ), and time (seconds) for NaOCl with QMiX and NaOCl with 2% chlorhexidine (CHX). 1H Nuclear Magnetic Resonance (NMR) and 2D NMR (DOSY) spectroscopy analyzed precipitation formed from NaOCl and QMiX. Results: Digital photography documented immediate, …
Viability Of Human Periodontal Ligament Fibroblasts After Time In Tooth Storage Media, Scott Macdonald
Viability Of Human Periodontal Ligament Fibroblasts After Time In Tooth Storage Media, Scott Macdonald
Master's Theses (2009 -)
Periodontal ligament cell viability at the time of tooth replantation is of utmost importance for proper repair of the damaged tissues (1). Multiple different options are currently available for storage of an avulsed tooth. The goal of this study was to investigate new storage media and evaluate their ability to maintain cell viability over time. Materials and Methods: Cultured human periodontal ligament fibroblasts (hPDLF) were seeded on 96-well plates. These cells were exposed to different storage media including: Hank’s Balanced Salt Solution (HBSS), EMT Toothsaver (EMT), Save-A-Tooth (SAT), trehalose (T300), cell culture media, water, and different formulations of HBSS combined …
