| Question | Answer |
| the periodontium consists of tissues that support the teeth and is divided into ... | gingival unit attachment unit |
| The Gingival unit consists of | free gingiva attached gingiva alveolar mucosa |
| The attachment unit consists of | cementum alveolar process periodontal ligament |
| Masticatory mucosa is | thick epithelial covering and keratinized cells , underlying mucos is composed to dense collegin fibers |
| gingival sulcus | space between the free gingiva and tooth |
| characteristics of free gingiva | masticatory mucosa slight mobility eptihelium slight keratination no rete peg formation smooth light pink collagenous fibers |
| characteristics of attached gingiva | masticatory mucosa tightly bound thick epithelia layer keratinized rete peg formation light red to dark pink collagenous fibers |
| characteristics of alveolar mucosa | lining mucosa movable and elastic thinner epithelial layer nonkeratinized no ret peg formation smooth pink-red collagenous fibers with some muscle fibers |
| lamina propria | |
| gingivitis | inflammation involving the gingival tissues only |
| periodontal disease | infections of the structures around the teeth |
| Periodontal ligament fiber names | apical, oblique, horizontal, alveolar crest, free gingival, transeptal |
| The periodontium include what structures | gingiva, periodontal ligament fibers, alveolar bone, root cementum |
| functions of health gingiva | support, esthetics, protection, phonetics |
| Black triangle disease | open embrasures |
| lamina propria | an underlying connective tissue layer |
| sharpeys fibers | collagen fibers embedded in the cementum of alveolar bone |
| Where does the blood supply of ginvgival tissue come from? | supraperiosteal vessles |
| alveolar bone | thin covering of bone that surrounds the teeth |
| function of attachment apparatus | support, nutritive, formative, sensory |
| Two kinds of cementum | cellular acellular |
| What type of cementum is free of embedded cementoblases and is clear with out structure | acellular |
| What type of cementum has embedded ceementoblasts | cellular |
| where is acellular cementum found | covering the the cervical third of the root and sometimes extends over most of the root, not the apical portion. |
| were is cellular cementum found? | the apical portion of the root, sometimes forming OVER the acellular cementum |
| How does cementum grow | appositon (addition of new layers) |
| The socket in which the tooth rests is called? | alveolus |
| lamina dura | atchement lining of bone around the tooth |
| bundle bone | numerous layers of bone are added to the socket wall, forms the immediate attachment of the PDL with sharpys fibers |
| The bone between teeth with multiple roots is called | interradicular bone |
| alveolar crest group | fibers extending from the cervical area of the tooth to the alveolar crest |
| horizontal group | fubers running horizontally from the tooth to the alveolar bone |
| oblique group | fibers running obliquely from cementum to the bone |
| apical group | fibers radiating apically from the tooth to the bone |
| interradicular group | periodontal fibers between roots of multirooted teeth |
| The main portion of the PDL is composed of | bundles of white collagenous connective tissue fibers |
