Study Notes
- The periodontium surrounds teeth and attaches them to bone
- It is made up of gingival tissues, cementum, periodontal ligament, and alveolar bone
- Gingiva is part of the oral mucosa and covers the alveolar bone and tooth up to the CEJ
- The gingiva is made up of free gingiva, attached gingiva, interdental papilla, and gingival sulcus
- The free gingiva is unattached and allows for periodontal pockets to be measured
- The gingival sulcus is the gap between the tooth and free gingiva, and is attached to the tooth surface by the epithelium
- The interdental gingiva fills in spaces between teeth and can be triangular or col-shaped
- The periodontal ligament connects the tooth to bone
- The attached gingiva is attached to bone and is firm and resilient
- Cementum is a hard mineralized tissue that covers the root surfaces of teeth, and the alveolar process is the bone that surrounds teeth.
