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 one hour and 45 minutes 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 practical sessions, students should check Moodle for the explanation of that week’s practical session. These may be videos or step-by-step instructions with pictures.
Practice groups M1 and M2 will practice on Wednesday mornings from 10am to 2pm. Group A will do the practice on Thursday afternoon from 15.00h to 19.00h. There will be no change of practice groups, because M1 and M2 do exactly the same timetable, and with group A change the language.
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.
Evaluation systems and criteria
In person
Assessment will be ongoing, based on objective tests, evaluating the different aspects relating to the achievement of the proposed objectives, both in theory and in practice.
Assessment will be carried out as follows:
- Theoretical exam: 40%.
- Practical work: 40&.
- Continuous assessment: 60% of the total practical mark.
- Practical exam on the first part of the syllabus: 20 %.
- Practical exam on the second part of the syllabus: 20 %.
- Quizzes: 20%. Within this section. Five per cent of this will consist of a specific exercise to be completed during the theoretical Metals lesson.
To pass the course, students must pass all components (exams (theoretical and practical), lab work and questionnaires). Honours will NOT be awarded unless the average mark exceeds 9.
THEORETICAL EXAMS:
A theory exam will be held at the end of the semester. A mark of 5 is required to pass the exam. The exam may consist of: short-answer questions, multiple-choice questions, or a combination of multiple-choice and short-answer questions. If the exam consists of a combination of multiple-choice and short-answer questions, both parts of the exam must be passed.
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 represent 20% of the final mark; it is compulsory to complete them. They will serve as a means of monitoring progress in the assimilation of the theoretical content on a weekly basis; this constitutes the continuous assessment of the theoretical part of the module. The exercise to be carried out in the Metals lesson will account for 5% of the mark.
Second call EXAMINATION SITTING:
The June exam will be the same as the exam in the first sitting and will be marked under the same conditions as in the first sitting; it will be averaged with the rest of the marks for the course (tests and practicals).
STUDENTS WHO HAVE FAILED:
Students who fail and have to retake the module in the following academic year must sit the theory exam, practical exams and online quizzes again. If a student fails the average mark for the practicals, they will have to retake all the practicals, not just the practical exams.
