Abstract:
Temporomandibular disorders (TMD) are the most common cause of chronic orofacial pain. They are characterized by painful and hampered jaw function. Especially disc displacements, osteoarthritis of the temporomandibular joint and masticatory muscle problems are frequent. The pain is localized in the jaws, face and temples, and jaw opening may be reduced, asymmetrical or irregular with noises from the temporomandibular joints. In cases with restricted jaw mobility or when the pain is provoked or aggravated by jaw function, referral to odontological examination is indicated. The prognosis is good, but full recovery may take years.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Etiology
Three primary contributing factors have been identified.
Structural Joints: Fibrous Joints
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
