James Cook University Subject Handbook - 2020

DS2001 - Biological Sciences for Dentistry 1

Subject Description

In this unit students will be introduced to the biological sciences that affect normal growth, development and function of the oral cavity, together with some of the endogenous and exogenous factors that can affect oral health. This subject will lay the foundations for later studies of orthodontics by introducing craniofacial growth and development. Students will develop an understanding of how growth and development occurs in the orofacial region. In addition the many types of malocclusions, their developmental considerations and how these affect diagnosis and treatment of children will be a focus. The unit will also cover the timing, sequence, and mechanisms of tooth formation and eruption in the context of how dental changes relate to jaw development patterns. This will serve as a foundation for developing good diagnostic, treatment planning and treatment skills in dentistry. This unit will also focus on the biochemistry and cell biology underlying normal bone, tooth and soft tissue development. A special focus will be the nutritional requirements for the healthy development of dental and periodontal tissues, and will reinforce the links between nutrition and health which were established in Year 1. This subject will also introduce the genetic determinants of normal development and health, as well as the genetic bases of disease. Students will be introduced to genetic disorders and genetic risk factors for oral disease, including system genetic disorders that impact on oral health. This subject will also focus on the role of infection in oral disease, including the development of dental caries and periodontal disease. It will examine topics in bacteriology, virology, mycology and immunology pertinent to dentistry. A special aspect of this unit is to link the basics of microbiology to disinfection and sterilization procedures in the dental clinic. This subject will also discuss the chemotherapy of microbial diseases, as well as pathogenicity and immune responses. Students undertake 10 hours of school-based placement in this subject.

Learning Outcomes

• demonstrate knowledge of biomedical sciences which form the basis for understanding human growth, development and health
• understand the differences between normal and abnormal biology (and psychology) and their implications for function
• demonstrate knowledge of the primary infection control principles as they apply to dental practice
• use scientific method to identify the organisims responsible for diseases relevant to dental care
• understand the role of micro-organisms in dental caries and periodontal disease and the disease processes associated with each condition

Note that minor variations might occur due to the continuous subject quality improvement process, and in case of minor variation(s) in assessment details, the Subject Outline represents the latest official information.

Special Assessment Requirements

At the completion of DS2001, students will have met the 30 hour observational placement requirement (DS1002) and critical reflection, both of which must be completed to a professional standard as set by the College. Satisfactory attendance is required at (pre)clinical placements. Satisfactory academic and professional standard, as described in the College Assessment Guidelines, must be achieved in order to progress
