Results 1 - 7 of about 7 for tTartar: Calculus or tartar refers to calcified deposits on the teeth, formed by the continuous presence of dental plaque. Its rough surface provides an ideal medium for further plaque formation, threatening the health of the gingiva. Calculus absorbs unaesthetic stains far more easily than natural teeth.
Calculus accumulations occur in the absence of adequate oral care. Once formed, it is generally too firmly adherant to teeth to be removed with anything available to an individual at home; patients with calculus must therefore visit their dental professionals so that the calculus can be removed with ultrasonic tools and specialized sharp instruments.
| Temporomandibular joint (TMJ): Temporomandibular joint is the jaw joint and is frequently referred to as TMJ. There are two TMJs, one on either side, working in unison. The name is derived from the two bones which form the joint: the upper temporal bone which is part of the cranium (skull), and the the lower jaw bone called the mandible. The unique feature of the TMJs is the articular disk. The disk is composed of fibrocartilagenous tissue (like the firm but flexible cartilage of the ear) which is positioned between the two bones that form the joint. The TMJs are one of the only synovial joints in the human body with an articular disk, another being the sternoclavicular joint. The disk divides each joint into two. The lower joint compartment formed by the mandible and the articular disk is involved in rotational movement (opening and closing movements). The upper joint compartment formed by the articular disk and the temporal bone is involved in translational movements (sliding the lower jaw forward or side to side). The part of the mandible which mates to the under-surface of the disk is the condyle and the part of the temporal bone which mates to the upper surface of the disk is the glenoid (or mandibular) fossa.
Pain or dysfunction of the temporomandibular joint is commonly referred to as "TMJ", when in fact, TMJ is really the name of the joint, and Temporomandibular joint disorder (or dysfunction) is abbreviated TMD. This term is used to refer to a group of problems involving the TMJs and the muscles, tendons, ligaments, blood vessles, and other tissues associated with them. Some practitioners might include the neck, the back and even the whole body in describing problems with the TMJs.
| Temporomandibular joint syndrome: The problems associated with TMJ, usually involve pain or discomfort in the joints and ligaments that attach the lower jaw to the skull or in the muscles used for chewing.Temporomandibular joint disorder (TMJD, TMJ or TMD), or TMJ syndrome, is an umbrella term covering acute or chronic inflammation of the temporomandibular joint. The disorder and resultant dysfunction can result in significant pain and impairment. Because the disorder transcends the boundaries between several health-care disciplines—in particular, dentistry, neurology, physical therapy and psychology—there are a variety of quite different treatment approaches.
The temporomandibular joint is susceptible to many of the conditions that affect other joints in the body, including ankylosis, arthritis, trauma, dislocations, developmental anomalies and neoplasia.
| Third molar: The last of the three permanent molar teeth, also called wisdom teeth. There are four third molars, two in the lower jaw and two in the upper jaw, one on each side. Some people are born without third molars, and not everyone that has wisdom teeth has four of them.
| Tooth Numbering: standardized system for referring to specific teeth.
| Torus: A bony elevation or protuberance of normal bone. Usual locations are the middle of the roof of the mouth and on the tongue-side of the lower jaw bone.
| Trismus: Trismus is the inability to normally open the mouth due to one of many causes:
Pericoronitis (inflammation of soft tissue around impacted third molar) is the most common cause of trismus.
Inflammation of muscles of mastication. It is a frequent sequel to surgical removal of mandibular third molars (lower wisdom teeth). The condition usually resolves on its own in 10-14 days, during which time eating and oral hygiene is compromised. The application of heat (e.g. heat bag extraorally, and warm salt water intraorally) may help reducing the severity and duration of the condition.
Peritonsillar abscess, a complication of tonsillitis which usually presents with sore throat, dysphagia, fever, and change in voice.
