In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. [1] If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be ...

[14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Although factors such as the quality of saliva, using fluoridated toothpaste and chewing gum after meals can inhibit the growth of these bacteria and change the biofilm environment. Saliva containing more buffering agents such as calcium and phosphate ions alter the internal environment of dental plaque to become less acidic, favouring the ...
Prophylaxis: dental prophylaxis includes the removal of extrinsic staining using a slow-speed rotary handpiece and a rubber cup with abrasive paste, mostly containing fluoride. [21] The abrasive nature of the prophy paste, as it is known, acts to remove extrinsic staining using the action of the slow-speed handpiece and the paste against the tooth.

0.35 lbs or 5.6 oz fish: If you do not have fresh fish where you live, it is okay to use canned sardines. Cans vary but are usually about 3.75 ounces, so you may need more than one.
Barodontalgia is a symptom of dental disease, for example inflammatory cyst in the mandible. [13] Indeed, most of the common oral pathologies have been reported as possible sources of barodontalgia: dental caries, defective tooth restoration, pulpitis, pulp necrosis, apical periodontitis, periodontal pockets, impacted teeth, and mucous ...
A discredited study that set off a flurry of interest in using an antimalarial drug to treat COVID-19 has now been formally withdrawn. A scientific journal on Tuesday retracted the March 2020 ...
