Mouth infections, also known as oral infections, are a group of infections that occur around the oral cavity. They include dental infection, dental abscess, and Ludwig's angina. Mouth infections typically originate from dental caries at the root of molars and premolars that spread to adjacent structures. In otherwise healthy patients, removing ...
The host's immune system controls the bacterial colonization of the mouth and prevents local infection of tissues. A dynamic equilibrium exists notably between the bacteria of dental plaque and the host's immune system, enabling the plaque to stay behind in the mouth when other biofilms are washed away. [18]
Rothia dentocariosa is a species of Gram-positive, round- to rod-shaped bacteria that is part of the normal community of microbes residing in the mouth and respiratory tract. [ 1 ] First isolated from dental caries , Rothia dentocariosa is largely benign, but does very rarely cause disease.
Generally, the abscess can be eradicated through surgical drainage alone; however this is sometimes inadequate. Therefore, systemic antibiotic treatment may be required, but only if there is evidence of spreading infection. [9] As the bacteria involved are known, antibiotic therapy selection can be specific, based on published susceptibilities. [9]
However, there are some remedies used in the treatment of oral bacterial infection, in conjunction with mechanical cleaning. These include fluoride , which has a direct inhibitory effect on the enolase enzyme, as well as chlorhexidine , which works presumably by interfering with bacterial adherence.
Ludwig's angina (Latin: Angina ludovici) is a type of severe cellulitis involving the floor of the mouth [2] and is often caused by bacterial sources. [1] Early in the infection, the floor of the mouth raises due to swelling, leading to difficulty swallowing saliva. As a result, patients may present with drooling and difficulty speaking. [3]
Oral candidiasis is the most common fungal infection of the mouth, [77] and it also represents the most common opportunistic oral infection in humans. [78] Infections of the mouth occur in about 6% of babies less than a month old. [7] About 20% of those receiving chemotherapy for cancer and 20% of those with AIDS also develop the disease. [7]
Mayo Clinic Proceedings is a monthly peer-reviewed medical journal published by Elsevier and sponsored by the Mayo Clinic. It covers the field of general internal medicine. The journal was established in 1926 as the Proceedings of the Staff Meetings of the Mayo Clinic and obtained its current name in 1964.
