Pathology for Dental Students 1

Data

Official data in SubjectManager for the following academic year: 2024-2025

Topic

Basic pathological cellular responses underlying the various disease processes are taught during this course. These are discussed in the following seven main chapters: necrosis, degeneration, accumulation, growth disturbances, acute and chronic inflammation, circulation, immune pathology and general oncology. The most common and most important diseases are also discussed in details during the lectures and seminars.

The main educational task of this subject is to have the students understand the disease concepts as the unity of macroscopy, microscopy, clinical signs and symptoms, genetic and laboratory changes; factors that shape the clinicopathological thinking about diseases.

The general pathology course will form the very basis for the systemic / organ pathology as well as the subsequent clinical studies by teaching the etiology, pathogenesis and pathomechanism together with the gross morphological and microscopical changes of the various diseases. During this activity the principal and methodology of the diagnostic pathology will be covered.

The theoretical part of the subject consists of 2 lectures a week (28 lectures altogether). The practical part includes 2x45 min. practice a week (altogether 14x90 min. in the course of the semester), which begins with 4x90 min. autopsy (4 practices), followed by 10x90 min. histopathology (10 practices).

Conditions for acceptance of the semester

Maximum two absences, which means 2 practices, are allowed! Absences exceeding this rate (15% of the histopathology classes) in either semester will result in not signing the gradebook!

Mid-term exams

One digital photo, one histological slide and a theoretical question will be given to the students at the examination by the end of the first semester.

Making up for missed classes

Each missed seminar has to be made up for with another group in the same week.
