Core veneered all-ceramic restoration are possible substitutes for the strong but less esthetic metal core sub-structures. Combining the strength of ceramic cores and superior esthetics of a weaker veneer ceramic can result in a reliable and more biocompatible restoration. Zirconia has been recently used in prosthetic dentistry for the fabrication of crowns and fixed partial denture, in combination with CAD/CAM techniques. The purpose of this study was to examine the shear bond strength between zirconia core and porcelain by push-shear bond tester. Experimental industrially manufactured yttria partially stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramic blocks were used for this study. They were cleaned, dried and sintered at 1450℃ for 2 hours. After sintering, the specimens were sandblasted with 70 μm alumina at 3 bars for 15 seconds and treated 1% HF solution. Shear bond strength of six veneering ceramics to zirconia was analyzed. The microstructure of Y-TZP consists of small equiaxed grains and showed the dense and clear grains. In this study, shear bond strength range between 66.78 MPa and 20.08 MPa were obtained. The Triceram showed the highest value and Creation ZI was the lowest value. Some mixed failures with adhesive and cohesive types were observed by microscope.

Objectives: The purpose of this study was to suggest an effective instruction method for dental hygiene students by determining the degree of importance and satisfaction that they attach to the courses. Methods: Data obtained from a survey that was conducted on 654 dental hygiene students were analyzed. Statistical Package for the Social Sciences version 23.0 was used for the statistical analysis. A paired t-test was conducted to detect the differences between the degree of importance that the respondents attached to the courses and the degree of satisfaction they achieved. A comparative analysis of the two was performed using the IPA analysis. Results: Regarding the items, the respondents found the environment most important, followed by the content, method, perspective, and assessment. Regarding satisfaction, they were most satisfied with the environment, followed by the perspective, method, content, and assessment. Regarding the importance of ideal teaching, the respondents gave the highest priority to ‘a class in which the core content is summarized, emphasized, and explained.’ The satisfaction was the highest toward ‘PowerPoint-based classes in which the core content is well-organized.’ Based on the results of the IPA analysis, the respondents regarded 16 items as requiring maintenance and continuous efforts, 12 items as low priority, and 4 items as requiring excessive efforts and timely improvement. Conclusions: An ideal class requires the instructor to utilize various teaching methods that would enable the students to comprehend the detailed teaching content and elicit active interaction and feedback from the students through easy-to-understand lectures that are appropriate for students.
