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 can be difficult to access with normal oral hygiene methods.
A comparison of the outcome of periradicular surgery in teeth that had previously undergone surgical treatment versus teeth that were undergoing a surgical procedure for the first time showed that, after 5 years, 86% of surgically treated teeth healed with complete bone filling of the surgical cavity while only 59% of resurgically treated teeth ...
The diagnosis of toothache can be challenging, [35]: 80, 81 not only because the list of potential causes is extensive, but also because dental pain may be extremely variable, [44]: 975 and pain can be referred to and from the teeth. Dental pain can simulate virtually any facial pain syndrome. [44]
For decayed adult (permanent) teeth, partial removal (also referred to as "selective removal" [5]) of decay before filling the tooth, or adding a second stage to this treatment where more decay is removed after several months, may be better than conventional treatment. [7]
The most common location of dry socket: in the socket of an extracted mandibular third molar (wisdom tooth). Since alveolar osteitis is not primarily an infection, there is not usually any pyrexia (fever) or cervical lymphadenitis (swollen glands in the neck), and only minimal edema (swelling) and erythema (redness) is present in the soft tissues surrounding the socket.
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 spread of infection from a dead tooth (i.e. which has undergone pulpal necrosis). To reflect this, sometimes the term "lateral (periodontal) abscess" is used.
Periapical true cysts - cysts containing cavities entirely surrounded in epithelial lining. Resolution of this type of cyst requires surgical treatment such as a cystectomy. [10] Periapical pocket cysts - epithelium lined cavities that have an opening to the root canal of the affected tooth. Resolution may occur after traditional root canal ...
In the generalized form, all teeth are involved. In the localized form, only a few teeth are involved. The most common teeth affected are the upper lateral incisors and third molars. Teeth affected by microdontia may also have abnormal shape, and the abnormal size may affect the whole tooth, or only a part of the tooth. [1]
