X-ray images of the body are an indispensable diagnostic tool in modern medicine. Medical imaging allows for the nonintrusive detection of dental cavities,bonefractures, foreign objects, and diseased conditions such ascancer. Standard X-ray images easilydifferentiatebetween bone and soft tissue; additio...
To get an idea of how much radiation is in an X-ray, take a look below: Chest X-ray: -0.1 mSv, or about 10 days of natural background radiation Dental X-ray: -0.005 mSv, or less than a day's background radiation Spine X-ray: -1.5 mSv, or about 6 months of background radi...
0.3-0.6 mSv/yr (30-60 mrem) is a typical range of dose rates from artificial sources of radiation, mostly medical. It includes bone density scans, dental X-rays, chest X-rays, and bone X-rays. 0.01-.03 mSv (1-3 mrem) is typical radiation from a single coast-to-coast airplane flig...
X-RayRadiationThe purpose of this research was to prove or disprove the widely held beliefs that X-ray radiation used in medical or dental applications may affect the normal oral flora, and may also have effects on the micro-organisms existing in the oral cavity of every person. Such beliefs...
The incidence of chromosomal aberrations were evaluated in the lymphocytes of peripheral blood of 40 persons working in different dental colleges and clinics in and around Bangalore occupationally exposed to X-rays. The age range of the study group was 25-65yrs and duration of exposure of dental ...

Because of the direct or indirect effects of ionizing radiation, oral complications such as dental caries, xerostomia, oral mucositis, taste alteration, and candidiasis are frequent during and after treatment. Taste, which allows us to sense sweet, salty, sour, bitter, and umami (i.e., savory...
and forming images corresponding to the X-rays having different energy levels; substituting a part of the detection values into a predetermined calibration function to determine the mass thickness of the object; and selecting weighting factors for the detection values based on the mass thickness to ...
In recent years, image-pickup apparatuses including a flat panel detector (hereinafter abbreviated as an FPD) formed by using a semiconductor material have been commercialized as image-pickup apparatuses that are used to perform a medical image diagnosis or nondestructive testing by using X-rays. ...
