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.
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.
The presence of dental plaque or infection beneath an inflamed operculum without other obvious causes of pain will often lead to a pericoronitis diagnosis; therefore, elimination of other pain and inflammation causes is essential. For pericoronal infection to occur, the affected tooth must be exposed to the oral cavity, which can be difficult ...
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 from the tooth pulp (odontogenic infection), or into a periapical cyst, where an epithelial lined, fluid-filled structure forms.
Its lining is derived from the epithelial cell rests of Malassez which proliferate to form the cyst. [2] Such cysts are very common. Although initially asymptomatic, they are clinically significant because secondary infection can cause pain and damage. In radiographs, the cyst appears as a radiolucency (dark area) around the apex of a tooth's ...
Green arrows indicate tooth decay. Blue arrows indicate abscess at root of tooth. The infection at the root of the tooth can travel through bone and infect surrounding soft tissue. Mouth infections are usually diagnosed on history and physical exam in the dental office or at a clinic visit with an otolaryngologist. [1]
Localised dental abscesses may be appropriately treated by intra-oral drainage via tooth extraction, opening of root canals and/or intra-oral incision and drainage. Wherever there are signs of spreading cervico-facial infection or significant systemic disturbance, however, patients should be referred urgently further management.
Severe tooth decay or infection (acute or chronic alveolar abscess, such as periapical abscess – collection of infected material [pus] forming at the tip of the root of a tooth). [6] Despite the reduction in worldwide prevalence of dental caries , it is still the most common reason for extraction of (non- third molar ) teeth, accounting for ...
