Operative dentistry is a part of Conservative dentistry that explores methods of keeping and using tooth without extracting, and is a science which researches arresting disease of teeth hard tissues and restoration of failure tooth. In this department, we investigate dental restorative materials and clinical techniques (methods) from view of Materials and Engineering or (and) Biology.
