Week+3+Big+Ideas



What were the Big Ideas in the reading and class discussions for week #3?

Chapter 4(same as week 1): The big idea for chapter 4 is how the gingiva functions to protect the underlying tissue against mechanical and microbial invasions. The histological changes make up the color, consistency, texture, contours and defines the physiological state of the gingiva. Chapter 5(same as week 1): The function of the periodontal ligament and the principle fibers is to protect the nerves and vessel from mechanical forces and provide nutrition. The cementum protects the dentin by covering the dentinal tubules and the alveolar process supports the tooth socket. All of these structures are necessary to function together to support the tooth.

CH. 4 & 5 (same as week 1) The periodontium has two parts: The gingiva and the attchment apparatus (PDL, cementum, and alveolar bone). The gingiva contains the marginal gingiva, the sulcus, the free gingiva, the attached gingiva and the interdental gingiva. These structures help function against mechanical and microbial invation. The attachment apparatus includes the PDL which attaches teeth to bone, the cementum which attaches PDL fibers to the tooth and protects the dentin, and the alveolar process which contains osteoclasts and osteoblasts. These are all the supporting structures of the teeth.

Chp. 4 & 5 Same reading material and concepts from week#1 Big Idea.
