Course/Module description:
The course is composed of frontal lectures, a laboratory demonstration, and student seminars. The frontal lectures comprise most of the course meetings, which focus on the following four primary topics: (1) Terminology and principles of materials science; (2) Structure and properties of the main dental materials, classified to families– polymers, ceramic materials, metals and composite materials; (3) The connection between the theoretical knowledge and its application in the dental clinic; (4) Research methods and scientific literature in dental materials. The student seminars involve student presentations and assessment of published research studies in the domain of dental materials.
Course/Module aims:
The course involves the comprehension of fundamental terms and principles in materials science, with particular emphasis on the relationships between material structures and their properties. The student should recognize the different families of materials and their characteristics, be able to classify dental materials and to apply this theoretical knowledge in practice, in the dental clinic. The final aim is to develop a competence in critical reading and assessment of research studies in the domain of dental materials.
Learning outcomes - On successful completion of this module, students should be able to:
• Define and describe fundamental terms and principles of material science.
• Relate between materials' structures and their properties.
• Classify dental materials into groups, while discriminating between the characteristics of the materials in the different groups.
• Recognize the correspondence between principles and characteristics of dental materials and their appearance in the dental clinic.
• Asses and compare dental materials, based on the knowledge of their composition and structure.
• Formulate a suitable selection of dental materials for specific cases, based on the theoretical knowledge.
• Analyze and criticize published research articles in the domain of dental materials.
• Conclude rational scientific decisions, explain and justify material choice for a specific dental treatment.
