Introduction
The study of the physico-chemical and behavioural characteristics of existing materials for dentistry use will provide the base for the clinical application of the concepts learnt during the degree programme.
It is a rapidly-changing field of knowledge, resulting from the constant research for better materials. We believe students should have in-depth knowledge of all their characteristics to reach an adequate clinical criterion for each situation.
Pre-course requirements
Those required for the bachelor’s degree programme.
Objectives
- To describe the basic physico-chemical principles on which the study of dentistry materials is based.
- To learn about the behaviour of biomaterials for dentistry use.
- To describe the different phases of the scientific method.
- To apply the scientific method to a problematic issue of dentistry materials.
- To define and appropriately use the terminology of dentistry materials.
- To understand articles published in journals specialising in dentistry materials, while interpreting them critically and applying what is learnt to new situations.
- To train the student in selecting and manipulating the different materials for dentistry use.
- To provide the student with the necessary preparation for effectively using current information sources.

Teaching and learning activities
In person
THEORETICAL MASTER CLASSES:
Theory classes will have a duration of two hours and will expand on the above mentioned topics, structured in the following manner:
- Introduction.
- Objectives.
- Contents.
- Directed basic bibliography.
The idea is teach in an instructive and informative manner with a critical and shared approach to the subject, inviting students to think about and deal with problems with a critical eye. Objectives of the master classes: To properly plan the different topic areas. To provide an appropriate structure for each theoretical class for the different sections. To complete a shared “teaching-learning” project. To improve note taking with a reflective approach after processing information. To encourage students to compare notes with classmates and with other sources of bibliographical information.
LABORATORY PRACTICAL SESSIONS:
These sessions are always related to the lecture given earlier in the day, so that when students start laboratory work, they have knowledge of the theoretical foundations of the subject.
Before the practice, students should look at the daily practice description in Moodle and answer a quiz to see if they have understood the description.
Practice groups M1 and M2 will practice on Wednesday mornings from 10am to 1pm, and on Fridays from 2pm to 5pm, plus one hour of assessable online practice. Groups M1 and M2 will go to the laboratory every other week, twice a week. Group A will do the practice on Thursday mornings from 8.00h to 11.00h. There will be no change of practice groups.
General objectives of the practical sessions:
- To develop the ability to observe.
- To obtain a certain level of manual skill.
- To become familiar with and understand the different materials used for dental purposes.
QUIZZES:
In Moodle, a quiz will be posted on the topics related to the lectures. It is a quiz per given topic and finished. If one week a topic is not finished the quiz will be done the following week. The quizzes will be available on Wednesday afternoons for the Spanish group and on Monday afternoons for the English group.
Evaluation systems and criteria
In person
Evaluation will be continuous, through objective examinations, assessing several aspects related to the achievement of set targets, on both a theoretical and practical level.
Evaluation will be as follows:
- Theoretical examinations: 40%, there will be two theoretical exams and each one is 20%.
- Practical sessions: 40%.
- Ongoing assessment: 45% of total practical grade.
- Quizzes from practical theory: 15%.
- Practical Exam 1: 20%.
- PRactical Exam 2: 20%
- Quizzes: 20%.
THEORETICAL EXAMS:
Two exams. Students who pass the first half of the semester will be freed from topics for the end-of-semester exam. The 2nd exam will be on the dates determined by the Faculty within the examination period.
The passing mark for the theoretical exams is 50%.
LABORATORY PRACTICAL SESSIONS:
Practical sessions shall be assessed continuously pursuant to the assessment criteria set forth in the practical session guide given to students at the beginning of the semester. Lecturers shall assess the acquisition of knowledge, skills, attendance and attitude.
Additionally, students shall sit two practical exams: at the mid-way point and at the end of the semester.
QUIZZES:
The quizzes will be 20% of the final grade, it is mandatory to answer them. It will be a way of seeing the progression in the assimilation of the theoretical contents on a weekly basis.
Second call EXAMINATION SITTING:
As for the other theoretical exams of the subject, the July exam the passing mark will be 50%, with an average calculated with the other course marks (quizzes and practical sessions).
Students who pass the mid-semester exam but fail the exam for the second half of the subject in January may resit only the failed exam, and an average grade shall be calculated with the first exam grade, the practical sessions and the quizzes.
