Impacted wisdom teeth is a condition where the third molars (wisdom teeth) are prevented from erupting into the mouth. [1] This can be caused by a physical barrier, such as other teeth, or when the tooth is angled away from a vertical position. [2] Completely unerupted wisdom teeth usually result in no symptoms, although they can sometimes ...
Pericoronitis. Pericoronitis associated with the lower right third molar (wisdom tooth). Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle. [2] The soft tissue covering a partially erupted tooth is known as an operculum, an area which ...
The third molar, commonly called wisdom tooth, is the most posterior of the three molars in each quadrant of the human dentition. The age at which wisdom teeth come through (erupt) is variable, [1] but this generally occurs between late teens and early twenties. [2] Most adults have four wisdom teeth, one in each of the four quadrants, but it ...
Commonly known as a dental cyst, the periapical cyst is the most common odontogenic cyst. It may develop rapidly from a periapical granuloma, as a consequence of untreated chronic periapical periodontitis. [1] Periapical is defined as "the tissues surrounding the apex of the root of a tooth " and a cyst is "a pathological cavity lined by ...
Impacted wisdom teeth happen when there's not enough room in your mouth for your third molars to emerge and they get stuck under your gum line. Why impacted wisdom teeth are so dangerous Skip to ...
Dentigerous cyst is labeled at top right. A dentigerous cyst, also known as a follicular cyst, is an epithelial-lined developmental cyst formed by accumulation of fluid between the reduced enamel epithelium and the crown of an unerupted tooth. [2][3][4] It is formed when there is an alteration in the reduced enamel epithelium and encloses the ...
Dentistry. A periodontal abscess (also termed lateral abscess, [1] or parietal abscess), [1] is a localized collection of pus (i.e. an abscess) within the tissues of the periodontium. It is a type of dental abscess. A periodontal abscess occurs alongside a tooth, and is different from the more common [2] periapical abscess, which represents the ...
Teeth may become impacted because of adjacent teeth, dense overlying bone, excessive soft tissue or a genetic abnormality. Most often, the cause of impaction is inadequate arch length and space in which to erupt. That is the total length of the alveolar arch is smaller than the tooth arch (the combined mesiodistal width of each tooth).
