Introduction

This course focuses study on the last stage of non-surgical treatment, root canal obturation. Root canal treatment promotes pulpoperiapical healing. Sealing the root canal system will maintain and prolong the clinical and radiographic success of the treatment and prevent recurrence of periapical pathologies. Obturation, therefore, has a fundamental value for medium and long term success of root canal treatment.

With this subject, students will acquire theoretical knowledge through an understanding of current scientific literature in the area of the root canal obturation and preclinical practice to achieve the ability to perform a full three-dimensional hermetic sealing of the root canals.

Pre-course requirements

No previous requirements.

Objectives

To know the requirements and objectives for a three-dimensional root canal filling.

To recognise the clinical criteria that determine when and when not to seal.

To know the most frequently used sealing materials in core obturation and be able to list their components and general properties.

To know the properties and functions of the ideal sealers.

To know and describe the technique of cold-lateral condensation: its advantages, disadvantages, indications, contraindications and clinical limitations.

To know and describe the thermoplastic techniques: types, advantages, disadvantages, indications, contraindications and clinical limitations.

To know and describe obturation techniques based on adhesive systems.

To know and describe the formation technique for the apical barrier with different materials, composition, characteristics, advantages, disadvantages and biological properties.

To know which obturation technique is suitable for different types of root canal morphology.

To analyse the clinical and radiographic criteria for assessing the quality of obturation.

Competences / Learning outcomes of the degree programme

Students will be expected to:

Demonstrate self-learning in the development of new instrumental techniques, in the acquisition of new scientific concepts, and in the search for new scientific information.

Argue and defend their own scientific ideas as well as to listen, analyse, evaluate and respond to the ideas of others.

Acquire learning skills that allow them to continue studying in a self-directed and autonomous manner.

Understand how to provide a basis or opportunity for originality in developing and/or applying ideas in a research context.

Acquire the capacity for analysis and synthesis of classic and contemporary literature on the field of study.

Apply acquired knowledge and develop a problem-solving ability in new environments within broader (or multidisciplinary) contexts related to the field of study in question.

Communicate conclusions to specialised and non-specialised audiences in a clear and unambiguous way.

Give presentations of their own clinical cases, based on the literature, using the correct terminology related to obturation of the root canal.

Acquire theoretical knowledge of different materials and the latest obturation techniques.

Acquire the individual ability and practical ability to perform clinical endodontics.

Understand and recognise the principles of ergonomics and safety at work (including the control of cross infection, radiation protection and occupational and biological diseases).

Acquire the scientific criteria to select the obturation technique appropriate to each case, as well knowing how to keep regularly updated about knowledge of new techniques and obturation systems, how they are used, their properties, indications and advantages.

Learning outcomes of the subject

Students will be expected to:

Know the materials and techniques currently available for obturation and their indications, advantages, disadvantages and clinical management.

Know the ideal properties of sealing materials.

Demonstrate critical ability in the selection of sealant cements for obturation.

Know the necessary requirements for the sealing of the root canal system and to know when and when not to fill the root canal.

Know the most appropriate technique for obturation according to different morphologies of root canals.

Know how to use the different existing equipment for sealing root canals and to be aware of the market.

Identify possible errors and know how to correct them.

Know the strategies to avoid the overfilling or overextension of the obturation material, as well as failure to obtain a suitable apical density.

Know how to make a radiographic assessment of the final filling of the root canal.

Know and understand classic and contemporary literature.

Teaching and learning activities

In person

FORMATIVE ACTIVITIES

METHODOLOGY

Seminar-instructive sessions

Scientific literature and manuals

Practical sessions

Materials and techniques applied in vitro on the CUO laboratories

The course objectives will be achieved through the compulsory attendance of training seminars. In some sessions students will have to prepare a summary or presentation based on the articles proposed by the teacher responsible for each seminar.

Evaluation systems and criteria

In person

Quarterly Continuous assessment: reading, critical analysis of textbooks and scientific literature by the student and teacher in charge of the subject.

Quarterly Continuous assessment: material handling and sealing techniques carried out on in vitro teeth in the laboratory of the CUO.

Theoretical and practical final exam: theoretical examination will consist of short questions on selected topics during the quarter (50% final grade). Practical examination: the student must submit electronically, radiographs of cases performed on in vitro teeth in the laboratory (50% of the final grade)
