The borders of the oral cavity include the lips in the front, cheeks on the side, mylohyoid muscle/associated soft tissue below, soft and hard palate above, and the oropharynx at the back. The most important structures within the mouth include teeth for chewing and the tongue for speech and assistance with swallowing.
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.
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.
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 ...
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.
Swelling can be observed in the right cheek. Periapical cysts begin as asymptomatic and progress slowly. Subsequent infection of the cyst causes swelling and pain. Initially, the cyst swells to a round hard protrusion, but later on the body resorbs some of the cyst wall, leaving a softer accumulation of fluid underneath the mucous membrane.
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.
An abscess originating from a tooth which has spread to involve the buccal space. Above, deformation of the cheek on the second day. Below, deformation on the third day. Sometimes the buccal space is reported to be the most commonly involved fascial space by dental abscesses, [2] although other sources report it is the submandibular space. [1]
