DOH133 Oral Microbiology (8)

This subject introduces micro-organisms, their characteristics and how they affect humans. Cultivation, enumeration, identification and control of micro-organisms are emphasised. Mechanisms by which medically important micro-organisms cause disease are introduced. The concepts of infection, inflammation and immunology are introduced in this subject. Infection control procedures are discussed in theory and applied in laboratory classes. An understanding of normal oral flora is developed in the subject. Hypotheses of oral disease aetiology, including specific, non-specific and ecological plaque hypotheses, are critically evaluated with respect to current peer-reviewed research findings. Practical skills developed in laboratory classes are used to solve dentistry-related case-based problems in a way that encourages independent, critical and reflective thinking.

Learning Outcomes

Upon successful completion of this subject, students should:
  • be able to describe the structure and function of micro-organisms;
  • be able to apply practical skills in microscopy, enumeration, isolation and culture of micro-organisms;
  • be able to describe and demonstrate how micro-organisms can be identified by biochemical and molecular methods;
  • be able to demonstrate knowledge of the means by which the growth of micro-organisms can be controlled, including managing the spread of infection in dental clinical practice;
  • be able to demonstrate a good understanding of the interactions of micro-organisms with humans with particular emphasis on the micro-organisms of importance to dental clinical practice; and
  • be able to explain, critically analyse and discuss current hypotheses of oral disease, including the specific, non-specific and ecological plaque hypotheses.
