Mechanisms of Periodontal Disease

Learning Objectives:  

After listening to and reviewing this podcast, the listener should:
  • Understand factors that contribute to the formation and progression of periodontal disease
  • Know how periodontal disease behaves and presents in the oral environment

The periodontium is the functional unit that surrounds and supports the dentition and is composed of the gingiva, the periodontal ligament, the cementum, and the bone. Gingiva is constituted by the free gingiva, the attached gingiva, and the interdental papilla. The periodontal ligament is located in the periodontal space between the alveolar bone and the cementum, which provides attachment for the periodontal fiber groups.  The bone, which is adjacent to the ligament space, is formed by the lamina dura and the alveolar bone.
