Students will develop a deeper understanding around the aetiology, management and treatment of dental caries and periodontal disease. Emphasis will be placed on the dental care of the adult population, including the treatment and management of root caries, advanced tooth wear. These subjects are interlinked with the study of caries prevention, oral health promotion and restorative procedures, all of which are assessed at a theoretical and practical level throughout the course.


  • To enable students to deliver oral hygiene instruction to patients using a variety of methods and material.
  • To describe the mechanism of fluoride application and its efficacy
  • To outline the classification and aetiology of dental caries
  • To outline the classification and aetiology of periodontal disease
  • To describe the principles of prevention of dental disease with an appreciation of the dynamics involved, including therapeutic educational, social and environmental factors.
  • To enable students to provide smoking cessation advice for patients

Intended learning outcomes

  • Have knowledge of the development of the teeth and jaws and normal anatomy and physiology, including the defence mechanisms of the dental and periodontal tissues
  • Have knowledge of the aetiology, pathology progression and presentation of periodontal diseases
  • Have knowledge of the aetiology pathology progression and presentation of dental caries
  • The epidemiology of periodontal diseases
  • Have an understanding of the role of microbial plaque in the causation of periodontal diseases; the variation in bacterial plaque with time and position on the tooth surface; and those factors which predispose to the deposition and retention of microbial plaque and calculus (i.e. local factors).
  • The role of systemic risk factors including systemic disease, hormonal factor, drugs and disorders of the immune mechanism, in modifying the course of periodontal disease
  • The use of screening and monitoring indices in the epidemiology of periodontal diseases and in the screening and monitoring of individuals
  • The management of patients whose medical status requires special consideration and for whom routine dental treatment may present a hazard, including those who may need antibiotic cover for treatment.
  • The management of patients who have acute periodontal disorders, comprising those of physical, chemical, bacterial, mycotic and viral origin.

Assessment Details

Formative methods of assessment are used in the form of written tests. This large subject contains many different elements; these elements are broken down and initially, tested individually. Once students begin clinical work, they need to apply these topics to their patient management and are subsequently assessed throughout their clinical work.

Aspects of this unit will have been delivered by the time the students sit their Oral and Dental Sciences exam

Format for Pre clinical examination:

  1. 1 written paper of 2 hours duration; 4 compulsory essay questions. 30 minutes allowed per essay question with a word count guide of 600.
  1. 2 hour extended short answer paper.

Pass mark: 50%

Re-sit examinations are scheduled following this examination. In the absence of special circumstances if a student were to fail a second time, the school would recommend that the student withdraw from the course.

A third attempt of the examination would need to be approved by the Board of Dental Studies.
