Oral Microbiology

Course Director: Jeffrey McLean
Credits: 2
Quarters/Yr of Program: Autumn / 1

Course Overview

Caries and periodontitis are the most common microbial based diseases that dentists treat every day, therefore future dentists must have a strong understanding of the basic microbiology behind the etiology of these diseases. The importance of these subjects (Microbiology and Pathology) is further reflected on the current Part 1 National Dental Board Exam, which dedicates ¼ to these topics. A similar emphasis on microbiology and pathology is anticipated in the new Integrated National Dental Board Examination.

Learning Objectives

The student who successfully completes this course will be able to:

1. Describe the principles of general microbiology, the factors responsible for virulence in select oral bacteria, the pathogenesis of infectious diseases (basic knowledge of immune responses, barriers, bacterial toxins, adhesins, mechanisms of escape against immunity, etc.)
2. Discuss the current state of dental microbiology, evolution of oral microbes, bacterial genetics (bacteria, mechanisms of horizontal gene transfer – transformation, transduction, conjugation, specific genetic elements – insertion sequences, transposons, integrons, etc.)
3. Explain the microbiological, biochemical and pathological aspects of dental plaque and biofilms.
4. Discuss and explain the bacteriological etiology and pathogenic mechanisms of the two major plaque-related diseases, caries and chronic marginal periodontal disease, and their possible sequelae.
5. Describe the principles of recombinant DNA technology and describe applications to dentistry.
6. Describe the bases of preventive measures and strategies directed against caries and periodontal disease.
7. Describe the principles of clinical asepsis.
8. Discuss the basic scientific rationale for the practice of dentistry with regard to the diagnosis, treatment and prevention of oral microbiological disease and their sequelae.
9. Identify the morphology and arrangement of bacterial cells.
10. Compare and contrast cell wall components in Gram-negative and Gram-positive bacteria. Describe how the cell structure differences cells leads to a given Gram stain result.
11. Describe how oxygen affects the growth of aerobes, obligate anaerobes, and facultative anaerobes.
12. Explain the differences between microbial colonization and infection and give examples of each process.
13. Describe the beneficial roles of normal flora in the host-microbe ecological relationship.
14. Describe and apply the newest approaches in culture independent microbiological techniques to understand the taxonomic and genomic diversity of oral bacteria.
