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.

Those required for the bachelor’s degree programme.

1. To describe the basic physico-chemical principles on which the study of dentistry materials is based.
2. To learn about the behaviour of biomaterials for dentistry use.
3. To describe the different phases of the scientific method.
4. To apply the scientific method to a problematic issue of dentistry materials.
5. To define and appropriately use the terminology of dentistry materials.
6. To understand articles published in journals specialising in dentistry materials, while interpreting them critically and applying what is learnt to new situations.
7. To train the student in selecting and manipulating the different materials for dentistry use.
8. To provide the student with the necessary preparation for effectively using current information sources.

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.

Each practical session shall begin with a short introduction that will show how the practice is performed, primarily so that students understand the sensory and motor objectives they must attain during the practical session.

M1 and M2 groups will do the practice on Wednesday morning from 10.00h to 14.00h,both groups at the same time in labs L3 and L3bis, and A group will do on Tuesday afternoon from 15.00h to 19.00h. No changes between practice group.

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:

Each week the students will have to fill in a quiz on the subjects of the course. There are weeks that can be a quiz and weeks that can be more than one.

Evaluation will be continuous, through objective examinations, assessing several aspects related to the achievement of set targets.

Evaluation will be as follows:

• Theoretical examinations: 60%.
• Practical sessions: 30%.
• Quizzes: 10%.

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 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.

The continuous assessment of the practical sessions shall represent 60% of the practical mark and the remaining 40% shall be the practical exam result.

QUIZZES:

The quizzes will be 10% 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.

JULY 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.
