Dental Case Scenario Questions

X-ray production X-rays are produced when the electrons are suddenly decelerated upon collision with the metal target (brehmsstrahlung) or "braking radiation". If the bombarding electrons have sufficient energy, they can knock an electron out of an inner shell of the target metal atoms.

ACRYLATES: ACRYLATES ACRYLATE AND ITS COMPOUNDS Dental polymer materials based on methacrylate , its polymer, and polyelectrolytes , seem to be a major cause of contact dermatitis in dental personnel These free monomers may cause a wide range of adverse health effects such as irritation to skin, eyes or mucous membranes, allergic dermatitis, asthma and paraesthesiae in the fingers.

Then the machine pumps the oxygen-rich blood to the rest of the body. The surgeon will then take an artery or a vein from your leg, arm, stomach, or chest. The graft is connected to the blocked coronary artery. The new blood vessel bypasses the blocked portion to create a …

X-ray Equipment X-ray equipment has three basic components: (1) the x-ray tubehead, which produces the x-rays, (2) support arms, which allow you to move the tubehead around the patient’s head and (3) the control panel, which allows you to alter the duration of the x-ray beam (exposure time) and, on some x-ray machines, the intensity (energy) of the x-ray beam.

X-ray absorption spectra: X-ray absorption spectra An x-ray absorption spectrum is generally divided into 4 sections: 1) pre-edge (E < E0) 2) x-ray absorption near edge structure (XANES), where the energy of the incident x-ray beam is E = E0 ± 10 eV 3) near edge x-ray absorption fine structure (NEXAFS), in the region between 10 eV up to 50 eV above the edge 4) extended x-ray absorption fine ...

An x-ray machine is like a giant camera that allows doctors to see what is going on inside a patient without having to do surgery. It took a long time for scientists to make the x-ray safe for medical use. Today’s x-ray machines produce a stream of electromagnetic radiation that interacts with an anode in an x-ray tube. The x-rays made by ...
