Study course description
Preliminary Knowledge:
Basic knowledge of biology, anatomy, histology, physiology, immunology, virology and general microbiology.
Objective:
Organised knowledge of the normal microflora in the oral cavity. Knowledge of oral bacteria classification and reclassification principles, morphology, properties, cultivation and identification methods. The oral cavity and the external environment; the normal microflora and its positive and negative effects; cariogenic bacteria and periodontal pathogens, interaction with macroorganism.

Assessment
Unaided Work:
Students will independently prepare presentations for seminars on cariogenic and periodontal microorganisms, their latest genotypes. In order to evaluate the quality of the study course as a whole, the student must fill out the study course evaluation questionnaire on the Student Portal.
Assessment Criteria:
Regular attendance and active participation in practical classes, successful completion of weekly tests.
Final Examination (Full-Time):Test
Final Examination (Part-Time):
Learning Outcomes
Knowledge:Obtain basic knowledge of the role of normal microflora in oral ecology, aerobic and anaerobic microorganisms, their role in etiology of hard and soft tissues in oral cavity, create competence in evaluation of pathogenesis of oral diseases.
Skills:As a result of the study course, the student will be able to collect and examine clinical material in the oral cavity, will be able to isolate a pure culture, determine and analyze changes in the number of microorganisms in the oral cavity.
Competencies:Combining theoretical knowledge with practical skills, students will be able to realise these skills in unitary integrative understanding about the importance of bacterial pathogenicity factors in the aetiology of oral diseases.
