Since bacteria that normally reside in the oral cavity cause mouth infections, proper dental hygiene can prevent most cases of infection. As such, mouth infections are more common in populations with poor access to dental care (homeless, uninsured, etc.) or populations with health-related behaviors that damage one's teeth and oral mucosa ...
The cause of this situation is usually a periapical or periodontal infection of a maxillary posterior tooth, where the inflammatory exudate has eroded through the bone superiorly to drain into the maxillary sinus. [59] An estimated 0.5 to 2.0% of viral rhinosinusitis (VRS) will develop into bacterial infections in adults and 5 to 10% in ...
Boils – Boils are the most common type of staph infection, they are pockets of white pus that start where a hair follicle or oil gland is. The boil is tender and red where the infection is located on the skin. Impetigo – Impetigo is most prominent among children, and is usually located around their mouth, nose, hands, and feet. It shows up ...
Strep throat is a common bacterial infection in children. [2] It is the cause of 15–40% of sore throats among children [7] [13] and 5–15% among adults. [8] Cases are more common in late winter and early spring. [13] Potential complications include rheumatic fever and peritonsillar abscess. [1] [2]
Scarlet fever develops in a small number of people who have strep throat or streptococcal skin infections. [1] The bacteria are usually spread by people coughing or sneezing. [1] It can also be spread when a person touches an object that has the bacteria on it and then touches their mouth or nose. [1]
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. [19]
Respiratory droplet transmission is the usual route for respiratory infections. Transmission can occur when respiratory droplets reach susceptible mucosal surfaces, such as in the eyes, nose or mouth. This can also happen indirectly via contact with contaminated surfaces when hands then touch the face. Respiratory droplets are large and cannot ...
In young children, this typically occurs in the upper respiratory tract mucosa. In adults, the infection is limited mostly to the tonsillar region. Some unusual sites of infection include the heart, larynx, trachea, bronchi, and anterior areas of the mouth including the buccal mucosa, the lips, tongue, and the hard and soft palate. [21]
