What is a Dentogingival unit?
What is a Dentogingival unit?
The dentogingival unit (DGU) has been described as a functional unit composed of the epithelial attachment and connective tissue attachment of the gingiva – both of which afford biological protection (1). Gargiulo et al.
What does periodontium consist of?
The periodontium is a connective tissue consisting of four components: cementum, the periodontal ligament (PDL), alveolar bone, and gingival tissue.
What is Sulcular epithelium?
The sulcular epithelium is that epithelium which lines the gingival sulcus. It is apically bounded by the junctional epithelium and meets the epithelium of the oral cavity at the height of the free gingival margin. The sulcular epithelium is nonkeratinized.
What is epithelial attachment?
Epithelial attachment refers to the mechanism of attachment of the junctional epithelium to a tooth or dental implant, i.e., hemidesmosomes. The cells of the epithelium at this attachment point are non-keratinized and form a collar around the tooth around the cemento-enamel junction.
What is long junctional epithelium?
The junctional epithelium (JE) adjacent to the tooth is that part of the gingiva which attaches the connective tissue to the tooth surface (Fig. 2.14). It forms a band 2—3 mm wide around the tooth, and is approximately 15—30 cells thick coronally and tapers to a single cell apically.
What is a periodontium definition?
The periodontium is a complex structure composed of the gingiva, periodontal ligament (PDL), cementum, and alveolar bone (Figure 11-1). The primary functions of the periodontium are to allow the tooth to be attached to the bone and to provide a barrier for the underlying structures from the oral microflora.
What is periodontium Slideshare?
The tissues that surround and support the teeth are known as the periodontium. It includes: 1- The gingiva. 2- The periodontal ligament. 3- The root cementum. 4- The alveolar bone.
What is Sulcular and junctional epithelium?
The sulcular epithelium lines the gingival sulcus from the base to the free gingival margin. The junctional epithelium is immediately apical to the base of the pocket, and coronal to the most coronal of the gingival fibers. The JE is attached to the surface of the tooth with the EA.
What is the function of the gingiva?
Gingival Structure, Function, and the Latest Research The gingiva (or gums) is the tissue that surrounds and protects the teeth and underlying bone. The gingiva is attached to the tooth, forming a seal that protects the underlying bone and helps provide a barrier against infection.
