Competences
Understand and recognize the biomaterial sciences essential for dental practice as well as the immediate management of possible allergies to them.
Know, critically debate and know how to use the sources of clinical information on dental materials collected in biomedical information
Handle, discriminate and select the appropriate materials and instruments in dentistry
Know the dental biomaterials: handling, properties, indications, allergies, biocompatibility, toxicity, waste disposal and environmental impact
Teaching methodology:
PRESENTIAL
The theoretical program will be given through master classes.
The seminars will discuss clinical cases adapted to the contents of the program as well as the analysis and solution of problems interactively between students and the teacher.
In the practices, the knowledge acquired will be applied in a practical way.
In the tutorials the teacher will personally attend to the students to guide them and resolve any doubts they may have. The tutorials will be essentially face-to-face, although they may be carried out electronically.
Evaluation system:
- Compulsory attendance at 90% of the practical activity and 80% of the theoretical classes to pass the subject.
- Practical content 30%: Continuous assessment: Participation and the acquisition of knowledge, attitudes and skills necessary to obtain the planned competences will be valued throughout the course, both in face-to-face and personal work. It will correspond to 30% of the final grade.
-Theoretical content 70%: 1 Written test with short questions (at the end of the semester). It will correspond to 70% of the final grade.
Recommendations for the subject:
General mandatory rules:
- It is mandatory to attend the practices with the CORRECT PROTECTION by the student, that is: clean gown and pajamas, mask, disposable gloves and very protective glasses.
- The theoretical and practical classes must begin with TIMELINESS: once started, no student will be able to join them.
- Those who do not follow the correct STERILIZATION rules and are not in possession of the INSTRUMENTAL will not be able to carry out the practices.
Observations:
In accordance with the Guidelines for the Development of a Safe Face-to-Face Teaching for the academic year 2020-2021, a contingency plan is established below for scenarios 2 and 3 with criteria for adapting the teaching methodology and evaluation system
SCENARIO 2

Teaching activities will include:
Synchronous master classes using Microsoft Teams.
Asynchronous classes through the Virtual Campus.
Interactive seminars using Microsoft Teams.
The practical activity will be face-to-face dividing the students into two groups that will participate alternating, seminars and practical part, throughout the course.

Recommendations for the study of the subject
Eminently theoretical content subject
Need of application in the study, rote and abstraction capacity
Practices oriented to the reinforcement, consolidation and understanding of the theoretical contents
Mandatory care and order during the handling of products and the use of facilities.
Scenario 2: distancing (partial restrictions on physical prespecialidad)
Expository and interactive teaching
a) Expository teaching may be carried out in whole or in part virtually.
b) In interactive teaching, physical and telematics can be combined, in any case guaranteeing for the first one a minimum of 50% of the practical hours of each subject.
Tutoring
Priority should be given to scheduling tutorials via telematics.
Evaluation
h) The final tests, if applicable, will preferably be telematic.
Mobility
i) Physical mobility will be combined with virtual mobility for both incoming and outgoing students, taking into account the mobility restrictions between territories and the conditions of the host universities.
Scenario 3: closure of the facilities (impossibility of teaching in person)
Expository and interactive teaching
a) Both expository and interactive teaching will be carried out completely in a virtual way.
b) The scheduled times must be maintained regardless of the teaching mechanism considered.
c) The centers must adapt the teaching of practices to a completely virtual modality.
Tutoring
d) The scheduling of tutorials (including those corresponding to TFG and TFM) will be & # 769; exclusively by telematic means.
Evaluation
e) The final tests, if applicable, will be telematic
