Study-Unit Description


CODE ORC2114

 
TITLE Science of Periodontics for Dental Hygienists

 
LEVEL 02 - Years 2, 3 in Modular Undergraduate Course

 
ECTS CREDITS 4

 
DEPARTMENT Oral Rehabilitation and Community Care

 
DESCRIPTION This study-unit covers the biological, medical and clinical sciences relevant to periodontology building on the foundations covered in Year 1. The students will cover the aetiology and pathogenesis of periodontitis including the role of the host, bacteria and the environment. We will also cover the diagnosis and management of other periodontal conditions. By the end of this study-unit, students will have been exposed to the aetiology of periodontal disease and discussed the implications of patients' systemic health status and its relation to oral health.

Study-unit Aims:

This unit aims to build on the students’ knowledge and understanding of the biological, medical and clinical sciences relevant to periodontology. Thus giving the students a greater understanding into the aetiology, pathogenesis and clinical presentation of periodontal diseases (difference between normal (health) and pathological conditions/disorders). By the end of the unit the students should have a full understanding of the causes of periodontal diseases, including the initiating, predisposing and systemic factors.

This study-unit aims to:
- provide students with an understanding of the causes of periodontal diseases, including the initiating, predisposing factors and systemic factors;
- provide students with an understanding of the role of bacteria in the pathogenesis of periodontal diseases;
- Provide students with the knowledge to help them classify the different types of periodontal disease in the clinical setting.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- Discuss the role of bacteria and the host in the pathogenesis of periodontal tissue destruction.
- Explain the histopathological development of periodontal diseases and the pathogenic mechanisms of inflammation.
- Discuss the immune reactions in the pathogenesis of periodontal diseases and how these lesions progress to deeper tissues (disease progression).
- Discuss the role of systemic diseases and deficiencies in the aetiology of periodontal diseases.
- Recognise the links associations between systemic diseases and oral health.
- Describe the clinical features of periodontal health, gingivitis and periodontitis and relate these to the aetiological factors and pathogenesis of these disease.
- Classify the different types of periodontal disease.
- Describe other conditions affecting the periodontium including; systemic disease, periodontal abscesses, endodontic-periodontal lesions.
- Explain the relationships between certain drugs/medications and gingival enlargement.
- Discuss the different skin and mucosal diseases that may cause non-plaque induced periodontal lesions.
- Demonstrate how the clinical and pathological features of these periodontal diseases and the differential diagnosis of these problems.

2. Skills:

By the end of the study-unit the student will be able to:
- Demonstrate knowledge of dental plaque and its role in the aetiology of oral disease.
- Demonstrate knowledge of the cellular and molecular mechanisms involved in the relationship between microbial pathogenesis and host susceptibility to infection/inflammation.
- List the different types of periodontal diseases.
- Identify for a patient’s medical history the various systemic diseases that contribute to the development and presentation of periodontal diseases.
- Identify clinically the various forms of periodontal disease in order to make a diagnosis.
- Identify clinically the different conditions that cause acute periodontal lesions and the differential diagnosis of these problems.
