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 ...
Combined periodontic-endodontic lesions may sometimes be abscesses, but these are considered in a separate category. A gingival abscess involves only the gingiva near the marginal gingiva or the interdental papilla. A periodontal abscess involves a greater dimension of the gum tissue, extending apically and adjacent to a periodontal pocket.
The interdental gum lies between the teeth. They occupy the gingival embrasure, which is the interproximal space beneath the area of tooth contact. The interdental papilla can be pyramidal or have a "col" shape. Attached gums are resistant to the forces of chewing and covered in keratin.
The main features are painful, bleeding gums, and ulceration of interdental papillae (the sections of gum between adjacent teeth). This disease, along with necrotizing periodontitis (NP) and necrotizing stomatitis, is classified as a necrotizing periodontal disease , one of the three general types of gum disease caused by inflammation of the ...
In patients who have habits such as clenching or grinding their teeth, a larger area of the buccal mucosa than just the linea alba becomes hyperkeratinized. This larger white, rough, raised lesion needs to be recorded so that changes may be made in the dental treatment plan regarding the patient's parafunctional habits.
Gingival abscess—a localized, purulent infection involves only the soft gum tissue near the marginal gingiva or the interdental papilla. [ 3 ] Periodontal abscess—a localized, purulent infection involving a greater dimension of the gum tissue, extending apically and adjacent to a periodontal pocket .
[4] [5] The middle or centre part of the interdental papilla is made up of attached gingiva, whereas the borders and tip are formed by the free gingiva. The central point between the interdental papillae is called the col. It is a valley-like or concave depression that lies directly beneath the contact point, between the facial and lingual ...
There are four embrasures for every contact area: facial (also called labial or buccal), lingual (or palatal), occlusal or incisal, and cervical or interproximal space. The cervical embrasure usually is filled by the interdental papilla from the gingiva; in the absence of adequate gingival tissue a black angle, or Angularis Nigra is visible.
