Cherubism is a disorder characterized by abnormal bone tissue in the jaw. Beginning in early childhood, both the lower jaw (the mandible) and the upper jaw (the maxilla) become enlarged as bone is replaced with painless, cyst-like growths.
Ameloblastic carcinoma is a rare malignant (cancerous) tumor that normally begins in the bones of the jaw. It is classified as an odontogenic tumor, meaning that it arises from the epithelium that forms the enamel of the teeth.
Temporomandibular disorders (TMD) are disorders of the jaw muscles, temporomandibular joints, and the nerves associated with chronic facial pain. Any problem that prevents the complex system of muscles, bones, and joints from working together in harmony may result in temporomandibular disorder.
Osteonecrosis of the jaw (ONJ) is a rare but serious condition that causes bone cells in your jawbone to die and your jawbone to poke through an opening in your gums. Because blood can't reach the exposed area, more of the bone dies. Osteonecrosis is the medical term for bone death.
Cherubism is a genetic disorder that affects the shape of your child's face. Noncancerous, painless growths form in your child's jaw, leading to a widened jaw and round cheeks. Some children have missing or abnormally developed teeth, or other signs like eyes that seem to gaze upward.
Condylar resorption is a rare condition that causes bones in your jaw joint to break down. People with this condition may notice their lower jaw looks like it's shrinking or retracting. Surgery on your jaw joint can correct the problem and realign your jaw.
Pierre Robin syndrome (PRS) is an uncommon birth defect. Babies with this disorder may have underdeveloped jaws and difficulty breathing. Their tongues may fall to the back of their throats. PRS may be mild or severe. In some cases, babies don't need treatment.
Meige syndrome affects how you move your face and jaw. You might move your face without meaning to or being able to control it. The most common symptoms include: Facial grimacing.
Monostotic Paget disease of the jaw is relatively rare (6–8). Case reports describing Paget disease in the jaw describe facial swelling and deformity as the presenting complaint. Most patients have pain, although not all. Often, patients have also been noted to have tooth resorption.
Mixed connective tissue disease (MCTD) is a rare systemic autoimmune disorder, which can affect the temporomandibular joint (TMJ). The literature on TMJ dysfunction in patients with MCTD is however sparse.
The 3 finger mouth opening test is a simple way to check your TMJ. Open your mouth and place three fingers between your teeth. If three fingers don't fit, it might mean your jaw isn't moving as it should. Another test is to press on the TMJ while opening and closing your mouth.
Hypermobility (looseness of the jaw) results when the ligaments that hold the joint together become excessively elongated, like being double-jointed. In hypermobility, dislocation is usually caused by the shape of the joints, ligament looseness (laxity), and muscle tension.
Usually, the infection is the result of bacteria entering the body through poor oral hygiene or oral surgery, such as a root canal procedure. To heal the infected bone, the body sends white blood cells to the area; however, persistent presence of white blood cells near the bone actually causes the bone to break down.
Symptoms referable to the jaw, such as pain, pressure sensation, numbness, swelling, expansion of the jaw, mobility of teeth, and epulis formation, were observed. In 7 cases the initial symptoms of myeloma were observed first in the jaws.
Paget's disease (PD) is a skin cancer characterized by epidermal infiltration of glycogen-rich vacuolated cells, termed Paget's cells, which usually present as single cells or nests1,2. Otherwise, extramammary PD commonly shows the various patterns of Paget's cells including the glandular pattern.
The cotton wool appearance is a plain film sign of Paget disease and results from thickened, disorganized trabeculae which lead to areas of sclerosis in a previously lucent area of bone, typically the skull. These sclerotic patches are poorly defined and fluffy.
Enlarged bones in the skull and spine can lead to pressure on the brain, spinal cord, or nerves and reduced blood flow to the brain and spinal cord. When Paget's disease affects the facial bones, the teeth may loosen. This may make chewing more difficult. Rarely, people with Paget's disease can develop bone cancer.
Marcus Gunn Jaw winking syndrome (MGJWS) is one of the congenital cranial dysinnervation disorders (CCDD) and these individuals have variable degrees of blepharoptosis in the resting, primary position. It is associated with synkinetic movements of the upper eyelid during masticating movements of the jaw.
Mewing is the practice, especially among young men, of placing one's tongue against the roof of the mouth to supposedly improve the structure and increase the attractiveness of one's jaw and facial structure (a practice that has not been found to be effective).
Rubber jaw syndrome (fibrous osteodystrophy) is a condition in which calcium in bone is replaced by softer connective tissue. It is caused by high levels of a hormone from the parathyroid gland. Hyperparathyroidism refers to elevated levels of parathyroid hormone in the blood.
Melkersson-Rosenthal syndrome (MRS) is a rare neurological disorder that affects facial nerves. It can cause facial swelling, furrows (grooves) in your tongue and facial paralysis. MRS may signify a future diagnosis of Crohn's disease or sarcoidosis. The condition is also called orofacial granulomatosis.
Often called Pierre Robin sequence, the disease is a chain of developmental malformations, each leading to the next. The condition is characterized by a smaller-than-normal lower jaw, a tongue that falls back in the throat and airway obstruction. In many cases, your child will also have cleft palate.
Collapse Section. Williams syndrome is a developmental disorder that affects many parts of the body. This condition is characterized by mild to moderate intellectual disability or learning problems, unique personality characteristics, distinctive facial features, and heart and blood vessel (cardiovascular) problems.
