 Periodontium | consists of the bone and soft tissues that surround and support the teeth |
| attatchment apparatis | Attatches the alveolar bone to periodontal ligaments |
| Cementum | thin layer of bone-like material that surrounds the root of the tooth |
| Alveolar Bone | The bone that supports the tooth in its position within the jaw. |
| Periodontal ligaments | Dense connective fibers that connect the cementum covering the root of the tooth with the alveolar bone of the socket wall. |
| alveolar process | a ridge that forms the borders of the upper and lower jaws and contains the sockets of the teeth |
| cortical plate | dense outer covering of spongy bone that makes up the central part of the alveolar process |
| alveolar crest | highest point of the alveolar ridge |
| alveolar socket | cavity within the alveolar process that surrounds the root of a tooth. |
| lamina dura | thin compact bone that lines the alveolar socket |
| Oblique group | fibers that protect the tooth against pressures of the long access of the tooth ex: chewing |
| Apical group | fibers that protect the tooth from twisting and falling out. can be found in single rooted teeth and multirooted tooth |
| Interredicular group | fibers that protect from tiping and twisting but are only present in multirooted teeth. |
| Horizontal group | fibers that prevent teeth from moving laterally aka up or down |
| keratinized | When tissue become very hard |
| oral mucosa | tissue that lines the oral cavity including : 1-Lining 2-Masticatory 3-Specialized |
| Alveologingival fibers | fibers that are sticking up and looking like spikey hair |
| Dentoperiosteal fibers | fibers that are coming out of the sides |
| Dentogingival fibers | fibers that are free and random |
| Circular fibers | fibers that form a circle |
| Cementum, Alveolar bone and periodontal ligaments | the periodontium is composed of the _____, _____ and ______ |
| Lining, masticatory and specialized | the 3 main types of oral mucosa are ____, ____ and ____ |
