The main educational aim of this course is the knowledge of the chemical, physical and biological properties of dental materials with a specific focus on mechanical properties and the predictability of clinical behavior of substances in in-vitro tests. The features and the singularity of the materials used in the clinical practice will be examined from the point of view of the final clinical treatment. The most recent scientific literature will be reviewed in order to provide a rational method for the correct selection of proper materials to be used in a clinical practice.

Dublin Descriptors
Knowledge and understanding
At the end of the course, the student will have to know the main characteristics of materials for dental applications.

Applied knowledge and understanding
The student must be able to carry out a detailed examination of the properties of materials illustrating the advantages and disadvantages of individual cases. Particular attention will be paid to interdisciplinary argumentation skills.

Judgment autonomy
The student must be able to autonomously evaluate, choosing among the various possibilities, which is the most suitable material for the specific dental application.

Communication skills
The student must be able to describe the topics covered during the course with an adequate property of language.

Learning skills
The notions acquired during the frontal lessons will be applied to practical examples in which the student will be asked to participate actively.

Fundamentals of chemistry.

The knowledge of chemical, physical and biological properties of dental materials is essential for their clinical use. The course will analyse the main characteristics of the dental materials used in dentistry and their application modes specifically for dental hygienists. The most recent scientific evidence in the field of materials for biomedical applications will be covered throughout the course.

The course will be focused on the following topics:
- Mechanical properties of materials.
- Stress-strain diagram, real graph and technical graph, material toughness, ductile-fragile transition temperature.
- Ductility, toughness, shear modulus or tangential elasticity modulus, Poisson coefficient.
- Cyclic loads and fatigue limit. Metal materials with fatigue limit. Hardness of materials.
- Stress-shielding, composite materials, mechanical properties of composite materials.
- Ceramic materials: properties and production.
- Polymeric materials for biomedical applications, composition and properties. Glass transition temperature.
- Definition of biomaterials and tissue engineering. Generation of biomaterials.

The assessment of learning will be conducted through partial oral exams related to the teaching modules that make up the integrated course. The grade for each partial exam will be expressed in thirtieths. During the partial oral exams, the student’s level of knowledge and competence on the program topics will be evaluated, and the correct understanding of the course contents will be verified through specific questions. In answering these questions, the student must demonstrate adequate language skills and reasoning abilities by connecting the various topics. The duration of the partial exams varies depending on the progress of the exam itself but will not be less than 30 minutes. The results of each partial exam will be published using the "Partial Exams" tool provided by the Esse3 platform. There will be a final call in which the Commission will review the results of the individual partial exams and record the final exam grade.
To pass the exam for the course, the student must obtain a grade of at least 18/30 in each of the partial exams. The student cannot reject the result of the individual partial exam but can only reject the final grade of the integrated course exam. In this case, the student will have to retake all the partial exams.
The student must register for the partial exam through the ESSE3 platform. The grade of the partial exam is valid until the end of the special session of the academic year in which the partial exam is taken. The final grade of the integrated course exam will be calculated as the weighted average of the grades of each partial exam, weighted by the CFU of each module. For the purposes of defining the weighted average of the final exam, any honors obtained in the partial exams will be valued as 1 point, i.e., a grade of 30 with honors in the partial exams corresponds numerically to a score of 31/30. To award honors to the final exam grade, the grade must be greater than 30.5/30.

Exam assessment
30 -30 cum laude: excellent knowledge of the topics and excellent language skills; the student is able to brilliantly apply theoretical knowledge to concrete cases and to readily connect the notions.
27 -29: good knowledge of the topics, remarkable language skills, good analytical skills; the student is able to correctly apply theoretical knowledge to concrete cases and to connect the notions.
24-26: good knowledge of the main topics, good command of the language; the student shows an adequate ability to apply theoretical knowledge to concrete cases.
21-23: the student does not demonstrate full mastery of the main teaching topics, even if fundamental knowledge is possessed; the intervention of the teacher is needed to answer the questions correctly; however, satisfactory properties of language is shown.
18-20: minimal knowledge of the main teaching topics and technical language, limited ability to adequately apply theoretical knowledge to concrete cases.
Insufficient (<18): the student does not have an acceptable knowledge of the program contents.

This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development (SDGs)
