OM may occur by direct inoculation of pathogens into the bone (through surgery or injury), by spread of an adjacent area of infection or by seeding of the infection from a non adjacent site via the blood supply (hematogenous spread). Unlike OM of the long bones, hematogenous OM in the bones of the jaws is rare. OM of the jaws is mainly caused ...
Actinomycosis abscesses grow larger as the disease progresses, often over months. In severe cases, they may penetrate the surrounding bone and muscle to the skin, where they break open and leak large amounts of pus, which often contains characteristic granules filled with progeny bacteria. These granules are often called "sulfur granules" due ...
Cysts rarely cause any symptoms, unless they become secondarily infected. [1] The signs depend mostly upon the size and location of the cyst. If the cyst has not expanded beyond the normal anatomical boundaries of the bone, then there will be no palpable lump outside or inside the mouth. The vast majority of cysts expand slowly, and the ...
Osteomyelitis (OM) is an infection of bone. [1] Symptoms may include pain in a specific bone with overlying redness, fever, and weakness. [1] The feet, spine, and hips are the most commonly involved bones in adults. [2] The cause is usually a bacterial infection, [1] [7] [2] but rarely can be a fungal infection. [8]
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]
Actinomycosis is an infection caused by a bacterium of the genus Actinomyces, usually Actinomyces bovis; the disease it causes has several common names. When it is a moveable tumour or lump on the jaw area, it is referred to as lump jaw; when it spreads into the hard bone of the jaw, it is referred to as big jaw; and when it affects the tongue ...
Symptoms: Buccal exostoses generally tend to be asymptomatic and are usually painless. However, they may increase patient concern about poor aesthetics, inability to perform oral hygiene procedures due to difficulty in cleaning around the area with a toothbrush, and compromised periodontal health by causing food lodgement, which could lead to ...
Noma (also known as gangrenous stomatitis or cancrum oris) is a rapidly-progressive and often-fatal gangrenous infection of the mouth and face. Noma usually begins as an ulcer on the gums and rapidly spreads into the jawbone, cheek, and facial soft tissues. This is followed by death of the facial tissues and fatal sepsis. Survivors are left ...
