A new classification has been proposed to classify gingival and palatal recessions. The new classification system gives a comprehensive depiction of recession defect that can be used to include cases that cannot be classified according to earlier classifications. A separate classification system for palatal recessions (PR) is also proposed.
Consequently, a new classification was developed at the International Workshop for a Classification of Periodontal Diseases and Conditions in 1999. This covered in much more detail the full range of periodontal diseases. "Adult periodontitis" was reclassified "chronic periodontitis" and "early-onset periodontitis" to "aggressive periodontitis".

Gum recession is a common problem in adults over the age of 40, but it may also occur starting in adolescence, or around the age of 10. It may exist with or without concomitant decrease in crown-to-root ratio (recession of alveolar bone ). 85% of the world population has gingival recession on at least one tooth with denuded root surface ≥1.0 ...
Generalized bone loss occurs most frequently as horizontal bone loss. [2] Horizontal bone loss manifests as a somewhat even degree of bone resorption so that the height of the bone in relation to the teeth has been uniformly decreased, as indicated in the radiograph to the rig defects occur adjacent to a tooth and usually in the form of a triangular area of missing bone, known as triangulation.
The alveolar process is also called the alveolar bone or alveolar ridge. [3] In phonetics , the term refers more specifically to the ridges on the inside of the mouth which can be felt with the tongue , either on roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth.
This condition occurs in association with denture wearing, and so those affected tend to be middle aged or older adults. 66-75% are estimated to occur in women. [1] Epulis fissuratum is the third most common reactive lesion that occurs in the mouth, after peripheral giant cell granuloma and pyogenic granuloma. [10]
Radiographic assessment should be carried out for patients with evidence of periodontitis to observe alveolar bone levels which can help to identify signs of AgP. [40] In healthy periodontal tissues, the distance from the amelocemental junction (ACJ) to the alveolar bone crest is typically in the order of 1mm in young people. [42]
Alveolar osteitis usually occurs where the blood clot fails to form or is lost from the socket (i.e., the defect left in the gum when a tooth is taken out). This leaves an empty socket where bone is exposed to the oral cavity, causing a localized alveolar osteitis limited to the lamina dura (i.e., the bone which lines the socket). This specific ...
