Week+1+Big+Ideas



What were the Big Ideas in the reading and discussion in class for Week #1? Ch.4 The gingival is composed of clinical and microscopic features which are designed to protect the roots of the teeth. When these features correlate with one another you are clinically see the tissues become red and inflamed due to the microscopic activity of the white blood cells that present during the infection. ES 33 Ch. 5 Teeth have structures that help support them and keep them in function. Some of these structures include: periodontal ligament, alveolar process which holds the teeth in place, cementum, and fibers that assist in this process. ES 33

Week 1 chapter 4,5: The clinical and microscopic features of the healthy periodontium and its main functions. Week 1: Ch. 4: The big idea for chapter four is the different components of the gingiva and how all of these components function together to help protect the underlying structures. The appearance of the gingiva, such as the color, texture, and shape, is also an indication of gingival health. ES 34 Ch. 5: The big idea for chapter five is the different structures that support the teeth. These structures support the teeth by functions such as providing physical protection and providing nutrition. There is a need for all of these components to function together in order to fully support the tooth structure. ES 34 Week 1 Ch 4. To me the big idea was the peridontium and what makes up the periodontuim: the gingiva, PDL, cementum and alveolar bone... these stuctures are the foundation the soft and hard tissues of the mouth. Ch.5 Chapter 5's big idea was the supporting structures of the teeth and how each structure has a specific purpose as means of support weather it be physical,nutritional, protection, remodeling or rebuilding. CA. CH. 4 & 5 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. Chapter 4: The gingiva and it's associated structures have many important functions and are all essential in a healthy mouth. The marginal gingiva,attached gingiva, interdental gingiva, and gingival sulcus can all be viewed clinically. The appearance of features, such as color, shape, consistency and texture, are all signs that reflect the health of the mouth and fundamentally indicate what's going on microscopically. -- AH28: The gingival epithelium has three parts; the outer epthelium, the sulcular epithelium, and the junctional epithelium. The oral epithelium as a whole contains cells that provide protection (ie Langerhans cells) and variation (ie:melanin from melanocytes) of oral tissue. -- Chapeter 5: Nearly every structure in the mouth has a supporting structure that is essential in the mechanics of functioning teeth and gums. Not only do these supporting structures support the hard and soft tissues in the mouth, they also provide nutrients, cellular activity, and protection. --AH28: PDL fibers play a major role in the support, nutrition, protection and function of teeth themselves and the surrounding tissues. The types of PDL fibers include transseptal, alveolar crest fibers, horizontal, oblique, apical and interradicular. -- Chapter 4: Clinical features that are observable and identifiable visually and how these features have microscopic components that if disturbed, present clinical manefistations; i.e., histologically= the immune host response to bacterial invasion. Chapter 5: All three elements of the attachment apparatus work collectively to provide a solid foundation and all have the ability to continually regenerate.

Chapter 4- This chapter’s big idea is focused on the clinical and microscopic features of the gingiva and how they correlate. Chapter 5- The periodontium’s principal components are the gingiva, pdl, cementum, and alveolar bone. The big idea of this chapter is the functions, development, and blood supply of the periodontium. -Ch. 4- Covers the gingiva and discusses the Clinical Features, which is divided into three parts: Free, attached, and interdental gingiva. The microscopic features discusses that the gingiva is composed of stratified squamous epithelium and underlying the gingiva is connective tissue. The gingival epithelium also has three parts; oral, sulcular, and junctional epithelium. It also covers the normal/healthy features of gingiva like the color, contour, consistency, and texture. -Ch. 5-The structures of the periodontium that surround and support the teeth include the gingiva, PDL, cementum, and alveolar bone. The chapter discusses the development, remodeling/repair, function, and blood supply of the PDL, cementum, and alveolar bone (attachment apparatus). Chapter 4,5- The two parts of the periodontium which include the gingiva and the attachment apparatus, which includes the cementum, aveolar bone, and the PDL. Chapter 4: 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: 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.

Chapter 4: The big idea for this chapter was the gingiva and all the components of it. It also discusses what healthy gingiva should look like as well as what unhealthy gingiva looks like. Chapter 5: The big idea for this chapter to explain all the tooth supporting structures (periodontal ligament, cementum, alveolar process). It talked about the function of all of these and how it all relates together.

Chapter 4 The gingiva surrounds teeth in order to provide resistance to mechanical (food particles) and microbial (host damaging bacteria) damage. The three types of gingival (outer, sulcular, and junctional) all function to create a barrier to keep foreign material out and its own material within. The junctional epithelium is directly attached to the tooth surface which creates an epithelial barrier against plaque bacteria, it allows access of gingival fluid and components of the host’s defense to the ginigival margin, the junctional epithelium has a rapid turnover rate so that it ca n quickly repair itself from damage. Below the epithelium is the connective tissue and its stability is a key factor in reducing the apical migration of the junctional epithelium. The appearance of the gingiva is a great indication of what is happening microscopically.

Chapter 5 The periodontium consists of gingiva, PDL, cementum and alveolar bone. All these tissues are structurally different but they all work to together. “The periodontium exists for the purpose of supporting teeth during function and depends on the stimulation it receives from function for the preservation of its structure” (Newman 86).

CH 4 The gingiva has many different parts and features that work together as a suppoting structure, this includes the gingiva fibers, parts include marginal gingiva, gingival sulcus, attached gingiva, and interdental gingiva. There are also different types of tissues within these structures and parts. The gingiva can be different colors, have different contours, shapes, consistency, texture, and position. CH 5 There are many different tooth supporting structures that work together but have their own function. There are three main parts of the attachment apparatus: the cementum, periodontal ligament, and alveolar bone. AS36
