Periodontal ligament 2. Gingiva 3. Cementum 4. Alveolar bone Periodontal ligament is (PDL)? - ANSWER - The PDL is a connective tissue complex made up of fiber bundles and cells What are the functions of the Periodontal Ligament (PDL)? - ANSWER - 1. Tooth anchorage (attaches teeth to bone) 2. Transmits occlusal forces to the bone and resists impact of these forces 3. Supplies nutrients to periodontal structures 4. Sensory functions include touch, pressure and pain 5. Acts as a shock absorber for the teeth, nerves and blood vessels (All PDL fibers attach to the tooth's cementum) What are Sharpey's fibers? - ANSWER - Fibers bundles that are attached and embedded in cementum and bone What are Transseptal Fibers? - ANSWER - 1. "Interdental ligament" 2. Extend interproximally over the alveolar crest 3. Hold teeth in interpromixal contact with each other (between the teeth) What are the gingival fibers? - ANSWER - Group of fibers that encircle the tooth, helping to maintain gingival integrity (not part of the PDL) What are Alveolar crest fibers? - ANSWER - Located apical to the junctional epithelium. Resists tilting and horizontal forces. What are Horizontal fibers? - ANSWER - Resist horizontal and tilting forces What are Apical fibers? - ANSWER - 1. Extend from apical area of the tooth to base of the tooth socket. 2. Resist "extrusive" forces 3. Prevents the tooth from being lifted out of the bony socket (tip of the root) What are oblique fibers? - ANSWER - MOST NUMEROUS FIBER, resists " intrusive" or "vertical" masticatory forces, prevents tooth from jamming into socket (diagonally) What are Interradicular fibers? - ANSWER - 1. Found ONLY in multi-rooted teeth 2. Located in tooth furcations 3. Stabilizes tooth root
