Purpose: The purpose was to measure the pressure exerted under a simulated mandibular edentulous impression at different locations using commonly used impression materials and four impression tray configurations.
Materials And Methods: This study was performed using an oral analog that simulated an edentulous mandibular arch. Three pressure transducers were embedded in the oral analog-one pressure transducer in the anterior ridge area, and the other two in the right and left buccal shelves.
Purpose: The first purpose of this study was to compare the retentive values of zinc phosphate and Panavia F resin cements when used for luting cast dowel and cores. The second purpose was to determine whether the use of a lubricant when making the resin pattern for a custom dowel and core would have an effect on the final retention of dowels cemented with either zinc phosphate or Panavia F cements.
Methods And Materials: Sixty-three caries-free extracted single-rooted human teeth were randomly divided into three groups of 21.
Background: The authors tested the clinical longevity of disposable diamond burs. They cut a series of five preparations and assessed the leakage after restoring the tooth.
Methods: The authors prepared 10 teeth for Class V restorations, and used a new disposable diamond bur for each tooth.
Unlabelled: Statement of problem Light transmission through veneers affects the degree of polymerization of light-polymerized resin luting agents.
Purpose: Light transmission through different all-ceramic veneers when irradiated by 3 types of light-polymerization units was measured to evaluate the degree of polymerization. Material and methods The power outputs from a conventional halogen (3M Unitek), a plasma arc (Apollo 95E), and a high-intensity halogen (Kreativ Kuring Light Model 2000) light were measured by a radiometer.
