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 marginal gingiva is stabilized by the gingival fibers that have no bony support. The gingival margin, or free gingival crest, at the most superficial part of the marginal gingiva, is also easily seen clinically, and its location should be recorded on a patient's chart. [2]
Thus, if the entire height of the keratinized gingiva, from the free gingival margin to the mucogingival junction is 8 mm, and the probing depth on the tooth at that location is 2 mm, the effective width of attached gingiva is 6 mm.
The junctional epithelium, a nonkeratinized stratified squamous epithelium, [1] lies immediately apical to the sulcular epithelium, which lines the gingival sulcus from the base to the free gingival margin, where it interfaces with the epithelium of the oral cavity.
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 ...
When it comes to maintaining your health, you may be overlooking one of the most important parts of your body: your mouth. Gum disease is the most common oral disease, with studies estimating that ...
The gingival fibers, (H), extend from the cementum (B) into the attached gingiva. Some fibers extend coronally into the crest of the free gingiva, some horizontally, and still other extend horizontally over the crest of the alveolar bone, (C), and then apically to connect on the facial aspect of the buccal plate of the alveolar bone.
