In dental anatomy, the free gingival margin is the interface between the sulcular epithelium and the epithelium of the oral cavity. This interface exists at the most coronal point of the gingiva , otherwise known as the crest of the marginal gingiva.
The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the mesial and distal surfaces of the teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the ...
Non-plaque-induced gingival disease is an inflammation of the gingiva that does not result from dental plaque, but from other gingival diseases caused by bacterial, viral, fungal, or genetic sources. Although this gingival disease is less common than those which are plaque-induced, it can have a serious impact on the patient's overall health.
The EA is very strong in a healthy state, acting as a type of seal between the soft gingival tissue and the hard tooth surface. The deepest layer of the JE, or basal layer, undergoes constant and rapid cell division, or mitosis. This process allows a constant coronal migration as the cells die and are shed into the gingival sulcus.
In dental anatomy, the gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for groove) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin.
Many variables have been identified that influence the formation of dental calculus, including age, sex, ethnic background, diet, location in the oral cavity, oral hygiene, bacterial plaque composition, host genetics, access to professional dental care, physical disabilities, systemic diseases, tobacco use, and drugs and medications.
Using the mucogingival junction as the boundary demarcating the apical border of the attached gingiva, a periodontal probe is inserted into the gingival sulcus to measure how much of the keratinized gingiva coronal to the mucogingival junction is in fact attached to the underlying bone. The depth of the gingival sulcus, determined by the depth ...
Healthy gums fill and fit each space between the teeth, unlike the swollen gum papilla seen in gingivitis or the empty interdental embrasure seen in periodontal disease. Healthy gums hold tight to each tooth in that the gum surface narrows to "knife-edge" thin at the free gingival margin. On the other hand, inflamed gums have a "puffy" or ...
