X-RAY BEAMDIFFRACTIONANALYSIS In subgingival calculus. Copyright of Journal of Dental Research is the property of Sage Publications Inc. X-rays can detect several dental issues such as decay, cancers, root defects, infections, bone loss, calculus buildup, existing fillings, dental anomalies. ![]() Hydroxyapatite and octacalcium phosphate were most frequently found in that portion having porous and zonal structure. Plaque starts as a thin, sticky film produced by oral bacteria. 10.1177/00220345830620021901 Abstract The crystalline components of human dental calculus were investigated using microbeam x-ray diffraction analysis. Regular brushing and flossing can remove plaque, but poor oral hygiene can cause it to build up. The mechanism of the formation of dental calculus being considered in this paper is that octacalcium phosphate or brushite is forned during the initial stage of calcification of dental plaque, and is gradually hydrolyzed and transformed into hydroxyapatite and/or whitlockite. Dental calculus, also known as tartar, is a hardened form of dental plaque that can build up on your teeth over time. Those people living in non-fluoridated water. Brushite was unexpectedly rare, and no calcite was detected in any portion of human dental calculus. Adult radiographic examination for tooth decay is recommended every two years. In the portion of the homogeneous illustration showing high calcification, whitlockite is a main component. Show cavities (tooth decay) between teeth without x-rays, decay between teeth has to be very large to be diagnosable within the mouth at which point the. Abstract: The crystalline components of human dental calculus were investigated using microbeam x-ray diffraction analysis. Dental calculus disease, also known as tartar is the hardened plaque seen on the surface of many of the teeth along the gumline in this case.
