Gingival abscess—a localized, purulent infection involves only the soft gum tissue near the marginal gingiva or the interdental papilla. [3] Periodontal abscess—a localized, purulent infection involving a greater dimension of the gum tissue, extending apically and adjacent to a periodontal pocket. [3]
A periapical granuloma (also referred to as an 'apical granuloma' or 'radicular granuloma') is a mass of chronically inflamed granulation tissue that forms at the apex of the root of a nonvital (dead) tooth. [12] (Although not a true granuloma, given the absence of granulomatous inflammation, the term 'periapical granuloma' is widely accepted ...
A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess. In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth.
An abscess is a localized collection of pus which forms during an acute infection. The important difference between a periapical abscess and abscesses of the periodontium are that the latter do not arise from pulp necrosis. [12] Abscesses of the periodontium are categorized as gingival abscess, periodontal abscess and pericoronal abscess.
Odontogenic infections can be severe if not treated and are associated with mortality rate of 10 to 40%. [4] Furthermore, about 70% of odontogenic infections occur as periapical inflammation, i.e. acute periapical periodontitis or a periapical abscess. [3] The next most common form of odontogenic infection is the periodontal abscess. [3]
Endo-Perio: infection from the pulp tissue within a tooth may spread into the bone immediately surrounding the tip, or apex, or the tooth root, forming a periapical abscess. This infection may then proliferate coronally to communicate with the margin of the alveolar bone and the oral cavity by spreading through the periodontal ligament.
Periapical cysts comprise approximately 75% of the types of cysts found in the oral region. The ratio of individuals diagnosed with periapical cysts is 3:2 male to female, as well as individuals between 20 and 60 years old. Periapical cysts occur worldwide. Types of Periapical cysts: Apical: 70% Lateral: 20% Residual: 10%
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.
