Abfraction is a form of non-carious tooth tissue loss that occurs along the gingival margin. [2] In other words, abfraction is a mechanical loss of tooth structure that is not caused by tooth decay, located along the gum line. There is theoretical evidence to support the concept of abfraction, but little experimental evidence exists. [3]
If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted, and instead the injury site should be cleaned to allow the adult tooth to begin to erupt). Reassure the patient and keep them calm. If the tooth can be found, pick it up by the crown (the white part). Avoid touching the root part.
A keyhole notch is typically considered as a slit ending in a hole of a given radius. This type of notch is most often considered in numerical models. [3] Fracture toughness results obtained from keyhole notch testing are often higher than those obtained from V-notched or pre-cracked specimens.
An enamel fracture occurs when the outer layer of the tooth, known as enamel, is fractured without directly impacting the underlying tooth tissues of the dentine or pulp. [1] This phenomenon typically arises from hard, external forces impacting the tooth to induce enamel breakage. [ 1 ]
Dental plaque is a microbial biofilm which forms on teeth. This biofilm may calcify and harden, termed calculus (tartar). Plaque tends to build up around the gingival margin (the gumline) and in gingival crevices or periodontal pocket (below the gumline). The release of waste products from the bacteria living in the biofilm causes an ...
1) Enamel 2) Dentin 3) Junctional epithelium 4) Connective tissue 5) Alveolar bone 6) Gingival margin 7) Sulcular epithelium 8) Gingival epithelium 9) Cementum The dentogingival tissues consist of many constituents, such as the enamel or cementum of the tooth and the connective tissue supporting epithelia like the junctional epithelium, the gingival epithelium and the sulcular epithelium.
It manages cleans effectively without excess pressure along the gum line, where gum disease tends to start forming. See it! One of the most innovative features of the ExpertClean 7500 is its app ...
It is a very thin, black-blue line visible along the margin of the gums, at the base of the teeth. [1] [2] It is caused by the reaction between circulating lead and sulphur ions produced by oral bacteria, forming deposits of lead sulfide in the gums. [3] The sign was described in 1840 by Henry Burton: [4]
