- 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.
Apply the knowledge gained in this unit by referring for, selecting and carrying out appropriate treatment for emergency periodontal patient.

- Describe conditions that require consultation with a patient's physician.
- Describe changes in oral tissues observed with systemic diseases and conditions.
- List modifications needed to best treat patients with systemic conditions.
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:
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:
- 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:
- State the etiological factors, prognosis, and the role of the dental hygienist in the treatment, and prevention of the conditions listed below:
Aid in the identification of etiologic factors and diagnoses of various periodontal conditions. The student will be able to treatment plan for the treatment of these conditions.
- Explain the ADA and other classification systems in different gingivitis and periodontitis cases.
- Describe thoroughly the clinical characteristics including radiographic signs of the various types of periodontitis:
- Differentiate all types of periodontal and gingival pockets.
- Recall in detail the histological steps of pathogenesis of the periodontal lesion.
- Explain the pattern of destruction by the inflammatory process.
- Describe the etiologic factors and mechanisms of periodontal tissue destruction.
- State the prognosis for various conditions of periodontitis.
- Briefly describe treatment (including chemical intervention) and maintenance procedures for periodontitis.
- Define gingival recession.
- Discuss the clinical characteristics of Stillman's Cleft, and McCall's festoon.
Assess and identify signs and symptoms of traumatic occlusion and TMDs. The student will possess a general knowledge of treatment protocol in order to be able to explain the options available to the patient.
- Compare and contrast primary and secondary occlusal trauma.
- List clinical, radiological, and pathogenic characteristics of occlusal trauma.
- Describe the adaptive capabilities of the periodontium.
- List situations that increase the magnitude or frequency of occlusal forces.
- Discuss the prognosis and treatment of occlusal trauma.
- Review and describe the procedures for clinically assessing jaw function, occlusion and TMD.
- Explain the causes, sign and symptoms and treatment options with TMD.
Assess the general medical and dental health in relationship to periodontal health, assess the periodontal status and create an ideal treatment plan for various different periodontal cases.
- Recall the purposes and areas covered of the medical and dental history, including chief complaint, with special emphasis on those related to periodontics.
- State the criteria and method used to evaluate and record the following:
- Explain what factors are used to establish a prognosis.
Gain a beginning knowledge of selecting and carrying out appropriate nonsurgical therapy for the periodontally involved patient.
