Influence Of A 3-Step Disinfection Procedure On Dentin Bond Strength, Maria Pappas
Influence Of A 3-Step Disinfection Procedure On Dentin Bond Strength, Maria Pappas
Theses and Dissertations
Statement of problem. Clinicians have used disinfection materials to remove surface contaminants during cavity preparation. It has been postulated that disinfection materials may negatively affect shear bond strength of restorative materials. If so, large numbers of restorations may be predestined for early failure with the use of a disinfection protocol.Purpose. To determine whether there is a difference in the bond strength between dentin and composite resin with a 3-step disinfection technique compared to a conventional bonding technique without the additional disinfection protocol.Material and Methods. Sixty human molar teeth were sectioned parallel to the occlusal surface to expose mid-coronal dentin and …
Comparative Tensile Strengths Of Preceramic And Postceramic Solder Connectors Using High-Palladium Alloy, Abdul-Hadi Shehab
Comparative Tensile Strengths Of Preceramic And Postceramic Solder Connectors Using High-Palladium Alloy, Abdul-Hadi Shehab
Theses and Dissertations
Purpose: To evaluate the tensile strength properties of Rx Naturelle Plus and Option (high-palladium) alloys on soldered connectors under simulated preceramic and postceramic soldering conditions. Materials and methods: Eighty cylindrical castings were fabricated (40 using Rx Naturelle Plus alloy and 40 using Option alloy). The 40 castings for each alloy were subdivided into 2 groups of 20 each. In the first group, castings for each alloy were randomly paired and soldered with SMG2 solder to produce 10 preceramic test connector specimens for each alloy. In the second group, castings were similarly paired and soldered with 490 fine solder to produce …
