The Effect Of Carrier Type And Material Used On Results Of 1,1,1,2-Tetrafluoroethane Application To Teeth, Jonathon Logan Williams Dds

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: The formulation of a pulpal diagnosis is crucial to prescribe appropriate treatment recommendations for endodontics. The application of a cold stimulus to the tooth’s surface utilizing the refrigerant 1,1,1,2-Tetrafluoroethane (R-134a) is a common way to obtain a pulpal diagnosis. Cotton as a form of applicator is used to absorb the R-134a and create a temperature change in the pulp. There is limited research if there is a better material than cotton to generate this cold response. No studies to date have been found to determine if a sponge as an applicator would generate a more significant cold response than …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: One objective of non-surgical endodontic therapy is the formation of a hermetic seal with elimination of any portal of entry of bacteria and their byproducts into the root canal space from periapical tissue. Extensive research has been conducted to determine ideal endodontic sealers. Bioceramic sealers have risen to prominence due to reported decreased shrinkage, less toxicity, and superior bond strength to root dentin compared to zinc oxide eugenol, calcium hydroxide, and resin-based sealers. GuttaFlow2®, a new sealer on the market, is composed of calcium silicate in combination with gutta-percha particles. Researchers from Coltene (Altstätten, Switzerland), the manufacturer of GuttaFlow2® …

Clinical Significance Of Gutta Percha Variability, Alex R. Pancake

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: The production of gutta percha points as root canal therapy filling materials vary from hand processing to machine processing with a range of acceptable levels of error (tolerance). Similarly, endodontic files manufactured to complement corresponding gutta percha points exhibit specified levels of tolerance. Investigations into the consistency among manufacturers of files and gutta percha points is limited. The aim of this study is to see how variability in apical gauge and taper of gutta percha points affected the clinical performance during cone try in.

Fracture Resistance Of Simulated External Cervical Resorption In Anterior Teeth Restored With And Without A Fiber Post., Michelle M. Romeo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: External cervical resorption (ECR) is a destructive type of external resorption that can be difficult to treat. ECR usually begins subgingival at the cementoenamel junction of teeth and continues apically and circumferentially. This substantial loss of tooth structure may make these teeth more prone to fracture and should be addressed when treatment planning teeth with ECR. The aim of this in vitro study was to evaluate the fracture resistance of treated and non-treated teeth with simulated ECR using two different treatment modalities.

Materials and Methods: Forty-eight extracted human permanent mandibular central incisors were selected. Teeth were randomly divided into …
