Outcomes and Objectives
- Assess normal characteristics of periodontal gross and microanatomy in order to be able to analyze the periodontium for health or disease status.
- list the four main structures of the periodontium, including their microanatomy.
- discuss the three types of oral mucosa.
- describe the five areas of the gingiva, including the following:
- clinical characteristics including healthy appearance
- explain what crevicular fluid is and what it does.
- compare and contrast histologic characteristics of oral epithelium and sulcular junctional epithelium.
- describe the lamina propria and the five major/six minor fiber groups involved with it.
- explain the purpose and functions of the periodontal ligament, include the major bundle groups.
- explain the purpose, type and anatomical terms of the alveolar bone.
- describe the normal contours in relationship to teeth and defects that can occur in alveolar bone.
- discuss the purpose and width of cementum.
- review and discuss the vascular supply, lymphatic and innervation of the periodontium.
- Interpret and utilize periodontal indices both in assessment of patients and understanding epidemiology community findings.
- Define the following terms:
- Explain various periodontal indices.
- Discuss the following factors in relationship to the prevalence and type of periodontal disease:
- host (age, sex, race, intraoral, and endocrine)
- environmental and etiological risk factors.
- Recognize and document the presence of local extrinsic and systemic intrinsic factors involved in the periodontal status of each patient.
- Define etiology.
- Explain why the etiology of periodontal disease is so complex.
- Differentiate between Extrinsic etiologic factors, Extrinsic contributing factors (local) and Intrinsic (systemic) contributing factors and whether or not they are direct causative or modifying agents (predisposing factors).
- Review the stages of development and composition of supra- and subgingival plaque.
- Discuss the pathogenic effect of plaque on the periodontium. Include the effects from the following items:
- bacterial invasion of the periodontal tissues
- direct injury
- host response within the immune system
- Review the formation, composition, modes of attachment, and mechanisms of mineralization of supra- and subgingival plaque (i.e., calculus).
- Identify the microorganisms specifically associated with diseases of the periodontium.
- Recognize and document the assessment data to communicate to the dentist for diagnosis and treatment planning.
- Describe when the following clinical terms are used:
- Correlate the visible oral changes of the gingiva in relationship to the histopathologic events of each stage in the pathogenesis of the various types of gingival conditions listed below . Keep in mind the following items to assess:
- surface texture
- State the etiological factors, prognosis, and the role of the dental hygienist in the treatment, and prevention of the conditions listed below:
- Chronic Plaque Associated Gingivitis: a. simple, b. modified by factors
- Steroid/Hormone Therapy: a. Puberty, b. Pregnancy
- Gingival Enlargement -
- Hypertrophy (Modified by local factors: a. Mouth Breathing, b. Eruption)
- Acute Gingivitis
- Necrotizing Ulcerative Gingivitis
- Acute Primary Herpetic Gingivostomatitis
- Other: a. Lichen Planus, Mucous Membrane Pemphigoid, Degenerative Conditions of Desquamative Gingivitis
- Aid in the identification of etiologic factors and diagno
