Study course description
Preliminary Knowledge:
Knowledge of oral anatomy and localisation names in Latin; normal skin and oral mucosae histology, physiology, pathological morphology, microbiology, pharmacology, the right steps in the investigation of oral cavity, interpretation of laboratory tests (blood, urine, biochemical, immunological tests), knowledge of the correct oral and perioral tissues investigation sequence.
To provide knowledge of specific skin, perioral tissue and oral mucosa diseases, their causes, pathogenesis, clinical and morphological manifestation, treatment and prevention. To create understanding of the relationship between the changes in oral mucosa and the general state of health.

Unaided Work:
Study of the clinical pictures of the skin disease and oral mucosa diseases in Atlases of Skin and Oral Pathology in order to identify primary and secondary elements, identify and practice describing the anatomical localisation of the pathology in Latin, understand the clinical expression of a disease. With the aim of training the visual memory and recognition of clinical manifestations of oral mucosa diseases study in e-studies the relevant clinical images and videos, inserted using the archives of the Oral pathology clinic. In addition, to study diseases of the oral mucosa from offered Oral Medicine and Oral Pathology books (relevant Journals) in the context with the respective disease. Completing the attached test tasks.
Assessment Criteria:
1) students’ participation in class activities; 2) ability to describe and analyze the specific clinical picture; 3) ability to recognize the morphological picture of certain diseases; 4) test tasks about traumatic lesions; 5) test tasks about bacterial diseases; 6) test tasks about viral diseases; 7) presentation of a certain topic of oral mucosal diseases. Mark in the exam is also the mark for the study course (100%)
