| Research Abstract |
Ultrasonic imagingis usedin many fields as a non-invasive technique and offers considerable potential in diagnosis as well as serving as a tool for research. The purpose this study was to ultrasonically determine the flaws inside the resin-dentin interface by using a phased array system. From the results, using the phased array method,flaws existing inside the resin-dentin interface could be detected. It was suggested that the phased array system could be used for analyzing qualitatively the status of the resin-dentin interface.
