Fracture Properties Of Different Orthodontic Bonding Materials, Daryl Lynden Proctor
Fracture Properties Of Different Orthodontic Bonding Materials, Daryl Lynden Proctor
Loma Linda University Electronic Theses, Dissertations & Projects
Spontaneous debonding has proven a constant problem since the introduction of bonded orthodontic brackets in the early 1960's by Newman1.
Components in classic bond strength testing are the bracket, the adhesive, the adhesive curing method, the type of teeth used, and the test method. These tests lead to extensive and compounding variables that make it difficult to evaluate the performance of any of the components individually.
The purpose of this study was to compare several contemporary orthodontic bonding adhesives by testing the physical and mechanical characteristics of the adhesives alone. Material properties compared were sonic and tensile measurements …
Hard Tissue Forming Potential Of Mta Compared To Common Root-End Filling Materials, Nooshin Noghreian
Hard Tissue Forming Potential Of Mta Compared To Common Root-End Filling Materials, Nooshin Noghreian
Loma Linda University Electronic Theses, Dissertations & Projects
An ideal characteristic of root-end filling materials used in endodontics is the ability to enhance hard tissue formation. Studies have shown that MTA has the potential to enhance hard tissue formation when placed in contact with periradicular tissues. The mechanisms involved in hard tissue formation of MTA and other root-end filling materials have not been completely elucidated. The purpose of this investigation was to study the mechanism of hard tissue formation of commonly used root-end filling materials and MTA by evaluating alkaline phosphatase (ALP) activity and cell layer protein. Extracts of materials tested in this experiment were added to the …
Evaluating Pit And Fissure Sealant Materials When Used As Bonding Agents In Preventive Resin Restorations, Paul Shields Gerber
Evaluating Pit And Fissure Sealant Materials When Used As Bonding Agents In Preventive Resin Restorations, Paul Shields Gerber
Loma Linda University Electronic Theses, Dissertations & Projects
Preventive resin restorations (PRR) are an increasingly popular alternative to the traditional amalgam restoration for small occlusal caries in posterior teeth. The technique for placing the PRR was first suggested by Simonsen (1980) and involved a minimal removal of tooth structure. After preparation, the tooth is etched, followed by an application of a bonding agent, filled with composite, and then sealed with a pit and fissure sealant. In an attempt to simplify the protocol of the PRR this study was designed to determine if pit and fissure sealant material could serve a dual role and eliminate the need for a …
