  2. Bone destruction patterns in periodontal disease - Wikipedia

    en.wikipedia.org/wiki/Bone_destruction_patterns...

    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.

  3. Periodontal diagnosis and classification - Wikipedia

    en.wikipedia.org/wiki/Periodontal_diagnosis_and...

    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.

  4. Chronic periodontitis - Wikipedia

    en.wikipedia.org/wiki/Chronic_periodontitis

    Chronic periodontitis is initiated by Gram-negative tooth-associated microbial biofilms that elicit a host response, which results in bone and soft tissue destruction. In response to endotoxin derived from periodontal pathogens, several osteoclast-related mediators target the destruction of alveolar bone and supporting connective tissue such as the periodontal ligament.

  5. Aggressive periodontitis - Wikipedia

    en.wikipedia.org/wiki/Aggressive_periodontitis

    According to the 1999 International Workshop for the Classification of Periodontal Diseases, aggressive periodontitis was defined according to 3 primary features, [17] in contrast to chronic periodontitis. [18] These features are common for both localized and generalized form of disease. [19] [20]

  6. Stafne defect - Wikipedia

    en.wikipedia.org/wiki/Stafne_defect

    The Stafne defect (also termed Stafne's idiopathic bone cavity, Stafne bone cavity, Stafne bone cyst (misnomer), lingual mandibular salivary gland depression, lingual mandibular cortical defect, latent bone cyst, or static bone cyst) is a depression of the mandible, most commonly located on the lingual surface (the side nearest the tongue).

  7. Debridement (dental) - Wikipedia

    en.wikipedia.org/wiki/Debridement_(dental)

    In dentistry, debridement refers to the removal by dental cleaning of accumulations of plaque and calculus (tartar) in order to maintain dental health. [1] Debridement may be performed using ultrasonic instruments, which fracture the calculus, thereby facilitating its removal, as well as hand tools, including periodontal scaler and curettes, or through the use of chemicals such as hydrogen ...

  8. Osteogenesis imperfecta - Wikipedia

    en.wikipedia.org/wiki/Osteogenesis_imperfecta

    Defects in the proteins pigment epithelium-derived factor (PEDF) and bone-restricted interferon-induced transmembrane protein (BRIL) are the causes of type V and VI osteogenesis imperfecta. [90] Defects in these proteins lead to defective bone mineralization which causes the characteristic brittle bones of osteogenesis imperfecta. [90]

  9. Furcation defect - Wikipedia

    en.wikipedia.org/wiki/Furcation_defect

    The bent "stick" on the left of the tooth is a piece of gutta percha being used to trace the defect. In dentistry, a furcation defect is bone loss, usually a result of periodontal disease, affecting the base of the root trunk of a tooth where two or more roots meet (bifurcation or trifurcation). The extent and configuration of the defect are ...
