Preclinical course of Endodontics
Course program
for III year students, 6th term
Department of Conservative Dentistry and Periodontology
Rationale for course and goals
1. Application of theory and technique in simulation to achieve competency for clinical
practice.
2. Demonstrate implication of internal tooth morphology to endodontic therapy.
3. Demonstrate application of rubber dam and techniques of tooth preparation for endodontic
treatment.
4. Demonstrate a precision needed in pulp cavity negotiation, preparation and shaping in
particular groups of teeth
÷ entrance and pulp chamber preparation in particular groups of teeth (upper and lower
incisors, upper and lower premolars, upper and lower molars)
÷ exploration of canal orifices in prepared teeth
÷ negotiation and preparation of radicular pulp cavity employing ‘step back’ technique
5. Demonstrate obturation of the radicular space with lateral condensation of gutta percha.
6. Describe properties, handling, application of medications and materials used during
endodontic therapy.
7. Identify, select and demonstrate management of instruments for operative endodontic
procedures.
8.
Organization of the course
Each student will work on a set of 4 extracted human teeth placed in plaster blocks
which include 1 incisor, 1 premolar, 1 upper molar, 1 lower molar. Four additional teeth will
be selected for the access preparation. Each session will begin with a short seminar discussing
issues and practical exercises scheduled for that session and will be followed by students
working in simulation according to the daily checklist. Students should stay focused during
seminars and listen carefully to instructor’s requests during practice period. Students are
expected to acquire the new material from each session’s seminar and their knowledge will be
verified during the following course day (a short quiz). Attendance in all scheduled sessions is
required in order to pass the course. If a student is not able to attend a course session he/she
must inform the course coordinator and the Dean’s office of the intended absence and reason
for that. For unexpected absences please contact us as soon as possible or have someone to
contact us on your behalf. Theory of each session missed must be acquired by a student and
will be verified by the instructor and the practical exercises included in the session done in the
period pointed by the instructor. Student will be asked to repeat the whole course if: will not
pass the final test 3 times, will not attend three session for unexcused or excused reason, will
not make the progress.
Assessment of students
The criteria for student’s assessment in preclinical endodontic course are as follows:
÷ Attendance (present, absent: excused, unexcused)
÷ Preparation & participation (prepared for the session, procedures started and
completed on time, procedures completed as planned)
o endodontic cavity preparation (access) in 8 teeth
o root canals of 4 teeth preparation with ‘step-back’ technique - performed
during sessions
o obturation of radicular space in 3 canals of 2 prepared teeth (1
incisor/premolar, 1 molar) employing lateral condensation of gutta percha
technique - performed during sessions
o interim dressing placement (calcium hydroxide) in 3 root canals using three
different techniques
÷ Professional behavior in simulation (properly attired, displayed correct simulated
patient/operator positioning, the simulation work place well organized, clean, and
uncluttered)
÷ Communication (appropriate use of the instructor’s time, consideration toward fellow
students and dental personnel, a positive and receptive attitude to evaluation and
feedback)
÷ Written test passed (60%-minimum to pass)
÷ Practical skills evaluation competency passed
Course Schedule and Location:
15 sessions (3h each; 4x45min) theory and practice
for details please check the Dean’s office
