Root canal

In the past, minor releases may have resulted from the use of consumer products (e.g., certain air deodorizers and cleaning products) that contained chloroform as a component or residual product (Bayer et al. 1988 Wallace et al. 1987a). Chloroform is widely used in laboratory work as an extractant. It is also still used in certain medical procedures, such as dental root canal surgeries (McDonald and Vire 1992), and in combination with aspirin as an experimental treatment for serious cases of herpes zoster (King 1993). These medical uses are extremely limited and would contribute very minor amounts of chloroform as releases to the air. 

In dentistry, they are used for sterilization of certain instruments and prevention and treatment of dental plaque and peridental diseases. They are also used in root canal therapy (RCT), treatment of acute necrotizing gingivitis and other infective oral conditions. Antiseptics and disinfectants are also used as ingredient in various dentifrices. 

Used for root canal therapy in dentistry as antiseptic. 

In dentistry, when astringents and antiseptics are used to harden and dry tissues of the pulp and root canal so that the tissues are resistant to infection, they are termed as mummifying agents. It is used in certain dental procedures when it is not possible to completely remove the pulp and contents of root canal. For this, generally a combination of various mummifying agents are used in the form of paste or semi-liquid preparation like tannic acid glycerine. 

Apical peridontitis- A severely inflammed pulp will eventually necrose, causing apical peridontitis, which is the inflammation around the apex of the tooth. It is characterised by severe spontaneous and persistent pain and regional lymphadenopathy can be present. Management is root canal treatment or extraction. Antibiotics are generally not necessary but patients should be advised to report back to dentist/physician, if swelling or other evidence of infection... 

Polyelectrolyte-based dental cements or restorative materials include zinc polycarboxylates, glass ionomers, a variety of organic polyelectrolyte adhesives as well as alginate-based impression materials. Dental cements are primarily used as luting (cementing) agents for restorations or orthodontic bands, as thermal insulators under metallic restorations, and as sealents for root canals, pits and fissures. They are also sometimes used as temporary or permanent (anterior) restorations. For further introduction to dental materials the reader is referred to standard texts [122,123]. 

Clove oil is an active ingredient in several mouthwash products and a number of over-the-counter toothache pain-relief preparations. It is also used to disinfect root canals. For toothache, clove tea has been used in combination with chamomile or sage. 

A tooth consists of three basic parts, the crown, which is exposed, the neck, which is at the gum line, and the root, which is embedded in the gum andjaw. The crown may be completely or partially covered with a harder substance known as enamel. The bulk of the tooth is composed of dentine, which surrounds and protects the inner pulp cavity. Pulp is vascular tissue that contains nerves and blood vessels, fed from below through a narrow channel in the dentine called the root canal. The root of the tooth is also surrounded by... 

Teeth that are still growing have an open root canal, but in those that have reached maturity, this canal is closed. Roodess teeth are those in which the root canal stays open and growth continues indefinitely. These are common in rodents like rabbits and gophers, whose teeth grow continually throughout...

Pneumomediastinum caused by subcutaneous emphysema has been reported in a 30-year-old man after the application of hydrogen peroxide solution to a root canal. The patient had acute pulpitis of the lower right third molar, treated by extirpation followed by irrigation with 3% hydrogen peroxide solution. Soon after irrigation, subcutaneous emphysema developed (2).

Stuff a cotton ball down into the pipet. Then use a wire to repeatedly tamp the cotton into the pipet. Give it 6 to 10 sharp jabs—much as if you were killing the nerves in a tooth during a root canal (Fig. 41b). You don t have to push the cotton all the way into the narrow part of the tip. Just wedge it firmly in the narrows.

Potential applications of this device are to be found in medicine, dentistry and areas of industry. The most obvious promise of this unique unit is in medical or dental emergencies and other field use where a quick fluoroscopic examination is desired such as, (1) examination of a football player s possible bone injury on the football field (2) root canal analysis and possible monitoring of surgical procedures and (3) industrial detection of welding defects or gas leaks in pipes.
