Restorative Dentistry
Solved Exam Questions
Course Introduction
Restorative Dentistry focuses on the diagnosis, prevention, and treatment of diseases and defects of teeth to restore their function, integrity, and aesthetics. This course covers foundational concepts in tooth structure, dental materials, caries management, cavity preparation, and the selection and placement of restorative materials such as amalgam, composites, and glass ionomers. Students will learn techniques for repairing tooth structure, managing complex dental cases, and ensuring long-term oral health, with an emphasis on patient-centered treatment planning, evidence-based practice, and advances in restorative technology. Preclinical and clinical experiences provide hands-on practice to develop proficiency in performing restorative procedures.
