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. This can be caused by tooth decay, broken teeth or extensive periodontal disease (or ...
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.
A phoenix abscess is an acute exacerbation of a chronic periapical lesion. It is a dental abscess that can occur immediately following root canal treatment. Another cause is due to untreated necrotic pulp (chronic apical periodontitis). [1] It is also the result of inadequate debridement during the endodontic procedure.
Other causes can include occlusal trauma due to 'high spots' after restoration work, extrusion from the tooth of root filling material, or bacterial invasion and infection from the gums. Periapical periodontitis may develop into a periapical abscess, where a collection of pus forms at the end of the root, the consequence of spread of infection ...
In 1890, W.D. Miller, considered the father of oral microbiology, was the first to associate pulpal disease with the presence of bacteria. [11] This was confirmed by Kakehashi, who, in 1965, proved that bacteria were the cause of pulpal and periradicular disease in studies using animal models; pulpal exposures were initiated in both normal and germ-free rats, and while no pathologic changes ...
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.
Periodontal abscesses may be difficult to distinguish from periapical abscesses. Since the management of a periodontal abscess is different from a periapical abscess, this differentiation is important to make (see Dental abscess#Diagnostic approach) For example, root canal therapy is unnecessary and has no impact on pain in a periodontal abscess.
Other symptoms may include hypoesthesia, paresthesia, and discomfort. [3] In rare instances, patients may experience associated facial swelling with the presence or absence of pain due to concurrent infection. [4] Patients experiencing symptoms also tend to be older and have the periapical form of cemento-osseous dysplasia. [3]
