Introduction

Detailed knowledge of the anatomical structure and the role of the two dentitions (temporary and permanent) of the human being is fundamental for the future dentist to able to successfully perform preventive and curative treatments.

The dental treatment is aimed at both restoring alterations of the dentition and their optimal form and function. Healthy dentition, both in form and function, is the model to imitate when performing procedures as diverse as prostheses, fillings, root canals or orthodontic treatments, and it is only by knowing the exact internal and external morphology of all the teeth that we can perform dental treatments with success.

 This course is essential for each and every one of the clinical disciplines that students will follow in subsequent courses.

Pre-course requirements

Knowledge of the anatomical structures of the head and neck, specifically in the oral cavity and teeth, will help students to understand aspects of dental eruption, tooth position and function within the complex neuromuscular system that performs such important functions as chewing and swallowing and that is significantly involved in speech and in the relationship between people.

Objectives

To gain knowledge of the precise and detailed external and internal anatomy of each tooth.

This anatomical knowledge will enable an understanding of the function of each individual tooth and of the dental groups to which they belong.

Teaching and learning activities

In person



There will be three hours of theoretical content being reinforced by three hours of lab sessions.

The contents of the week will be reinforced through tasks, questionnaires, forums, activities, etc.

Evaluation systems and criteria

In person



The final evaluation of the subject is made by means of the grade resulting from the sum of the grades of the following three blocks:


1-. PRACTICE: 40% of the final grade. The student must have a minimum of 50% of the score of this block to be able to pass the subject. It includes practical activities, delivery of drawings and carved teeth.

ATTENDANCE TO THE PRACTICES IS COMPULSORY. The absence with or without justification to more than three practices will make it impossible for the student to take the exam and therefore to pass the subject, having to make up the practices to be able to present to the second call. The student will have to pass an exam of the practice block.

2-. CONTINUOUS EVALUATION ACTIVITIES 10% of the final grade. Class and Moodle activities.

3-. THEORY: 50% of the final grade. Passing the fina exam is required to pass the subject
