Caries

 

a pathological process involving the gradual destruction of bony tissue or teeth.

Caries of bony tissue is caused by degeneration or infection of bone or periosteum that results in necrosis of portions of bone followed by absorption or disengagement of the dead tissues and formation of a bone ulcer. Caries may also be accompanied by specific inflammatory processes (for example, tuberculosis or syphilis). The mechanism of development and clinical symptoms of caries vary with the cause, location of the focus, and so forth. In acute inflammations (for example, osteomyelitis), when a focus of suppuration arises in bone and sometimes spreads to the surrounding tissues, caries is manifested by systemic intoxication, and bone destruction progresses rapidly. In chronic and especially specific processes, caries develops slowly without severely pronounced symptoms. Treatment consists in medication (antibiotics, sulfanilamides) and specific treatment (anti-syphilitic, antituberculotic). Surgery is frequently effective.

The devitalizing agents damage the pulp and periodontal fiber tissue; as a result, the tissue loses its metaplastic properties and no longer serves as a barrier for pathogenic stimuli from the tooth cavity.
These particles then can be compacted carefully with normal dental tools into a tooth cavity where they consolidate through cold welding.
The technique, called Terahertze Pulse Imaging (TPI), can measure the thickness of tooth enamel, display internal tissue or highlight the condition of the tooth cavity.
One of the first things they tried it on was teeth - and found it can measure the thickness of the enamel, show internal tissue or highlight the condition of the tooth cavity.
By focusing the beam directly at a tooth cavity, the dentist can pinpoint, target, and vaporize the exact area of decay within the tooth without hurting surrounding tissue.
On the X-ray image, denticles take the form of round or oval shades in the tooth cavity.
