227 .205 Lecture Notes - Lecture 1: Canine Tooth, Hypsodont, Gingival Margin
Document Summary
Clinical crown is thesection exposed above gingival(gum) margin. 2 main types of crowned teeth: short crowned teeth(brachydont) Gradually extruded as attrition(erosion) occurs on the occlusal(top surface), continues to grow until the roots form then it stops growing. Constricted portion of tooth located at the gum margin. Embedded in the alveolus (bony socket) connected by ligament to cement (covered by cementum) Is important for example. canine 1st molar in the lower jaw a)short crowned (brachydont) Cease to grow after eruption is complete then continue to be worn down. Relatively short crown exposed within oral cavity once eruption is complete. One or more relatively large roots that are embedded in the jaw. All carnivore, all teeth in pigs except the tusk except canines and incisors of ruminants b)high crowned (hypsodont) Continue to grow following eruption after the tooth has emerged from the gumline and start to come into wear. Most cases short roots eventually form and growth, continues feed mechanism.
