When failure of tissues to fuse together that are forming early in pregnancy, defect can happen and jaw is incomplete. [46] For example, cleft lip and palate when one of the jaw's embryological processes failed to fuse together or the agenesis of the condylar process of the mandible, which may be seen in hemifacial microsomia. [46]
From the inside, the mandible appears concave. On either side of the lower symphysis is the mental spine (which can be faint or fused into one), to which the genioglossus (the inferior muscle of the tongue) attaches; the geniohyoid muscle attaches to the lower mental spine. Above the mental spine, a median foramen and furrow can line the symphysis.
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]
The signs and symptoms depend upon the type of OM, and may include: Pain, which is severe, throbbing and deep-seated and often radiates along the nerve pathways. Initially fistula are not present. Headache or facial pain, as in the descriptive former term "neuralgia-inducing" (cavitational osteonecrosis). Fibromyalgia. Chronic fatigue syndrome ...
curving of the pinkie finger, one of the symptoms observed in tooth ankylosis. The signs and symptoms for patients can be varied mainly depending on the growing state of teeth (permanent or deciduous). Other factors, such as age, sex, site of infection may also lead to the occurrence of specific signs and symptoms, but their roles are not well ...
Cysts of the jaws are cysts—pathological epithelial-lined cavities filled with fluid or soft material—occurring on the bones of the jaws, the mandible and maxilla.Those are the bones with the highest prevalence of cysts in the human body, due to the abundant amount of epithelial remnants that can be left in the bones of the jaws.

Most of the upper jaw bones (premaxilla, maxilla, jugal, quadratojugal, and quadrate) have been fused to the braincase, while the lower jaw bones (dentary, splenial, angular, surangular, and articular) have been fused together into a unit called the mandible. The jaw articulates via a hinge joint between the quadrate and articular.
