Information for students

Information for students of DENTISTRY:


Subject of Epidemiology is taught in 6th class of DENTISTRY as semestral subject in winter semester (WS) of academic year . This means that for each study group the study are divided into 3 practical lessons (together 12 study hours) followed by the exam in regular  examination period, which includes writing test and oral exam.

Lectures started at the beginning of the winter semester, ongoing two hours 6 times  from the 3rd to 8th study week of the semester. Lectures are intended for all study groups only in this given semester (according to the schedule) within extent of 12 hours. List of lectures

Practical lessons for the certain groups always takes place in given time according to the schedule. Teaching consists of completing 3 days i.e. the total 12 hours of compulsory practical training (practicals) during two to three  weeks of instruction for each individual study group.  Sylabus for practicals

Following all practical lessons and full attendance of lectures are  esignated to good preparation for the exam in Epidemiology, which is usually at the end of semester or as preterm exams, after agreement of the Head of the Institute and confirmation of Vice-dean  for Dentistry.

All information about compulsory or recommended literature, questions for tests and examination are on the website of the institute.

Conditions for passing the practical training of Epidemiology:

1. The student must complete all the topics included in the content of practical training (3 complete days), thus not even have one absence.

2. The student must actively participate in teaching and engage in training. In case of repeated passivity student can be excluded by teachers from teaching and he/she must compensate for a given part.

3. If a student does not meet these conditions, practical part of teaching is recognized as incomplete and he/she cannot participate in the examination.


 Compensation for participation of students in practical lessons:

1. A student who did not complete practical classes in full course and has to replace them, or a part there of, must in advance, before substituting the classes, arrange it with the teachers responsible for teaching the course (E. Macháčová, MD). Indicating the reason why he/she could not have completed practicals in the given period, and in case of acceptance the reason  he/she may substitute teaching.

2. Compensation for practical classes in advance, before the date resulting from the schedule, is possible only in exceptional and serious reasons and for individual study under the Erasmus program, again in agreement with the responsible teacher.


Final examination in Epidemiology

The conditions for entry to the examination of the Epidemiology is passing prerequisites, i.e. examinations of Microbiology and Immunology (verification is done in AIS2) and passing practical training in Epidemiology (100% participation in practical classes). If a student fails to meet these conditions, he/she will not be admitted to the exam in Epidemiology.


Students in the block are registered for the examination via AIS2 after completing practical tuition (usually Friday evening). Block dates of examination are intended only for students of the relevant block and are stated in accordance with the study and examination regulations. In the examination period, there are next dates of the examination stated for students who have not passed or failed the exam in the block dates of examination.

On the exam day, the students present themselves at the Institute of Epidemiology at 7.15 a.m. and on presentation of the Index they take a written test. Everyone who achieves at least limit test points (70%) is proceeding to the oral examination. Those who do not reach the limit of the points have failed, and will be given mark Fx to AIS2. If a student does not reach the test limit repeatedly in two attempts, in the last third attempt he/she will nevertheless be examined orally. If a student reaches the limit of the points and fails the oral exam, he/she has not to write the test again. These rules also apply when moving the exam to the next class.

On the oral examination a student draws three questions (General Epidemiology, Special Epidemiology, Chronic Diseases) so that the examination can verify comprehensive students' knowledge of epidemiology ( see List of questions to examination).  The  condition for successful completion of the examination is to handle answers to all the questions. A student has the right to prepare a written response, examiner will provide him the necessary time, usually 30 minutes. Cheating during the examination is the reason to discontinue the exam and to Fx evaluation.

Absence at the examination in which the student is enrolled in AIS2 is automatically evaluated by Fx. Registration for an examination and potential cancellation of the examination date, which allows AIS2, is the responsibility of the student. If a student wants to cancel on a date AIS2 already does not permit, may do so in writing, by a letter to the Head of Institute. Similarly, if a student wants to apologize the registered term for which he did not took part in exam, he may do so within 5 days after the examination by a letter to the Head of the Institute, or bring a proof of the visit of the attending physician.
