A metallographic evaluation of porosity occurring in removable partial denture castings. 1979

A J Lewis

Conveniently sized sections from six removable partial denture castings were examined metallographically for porosity. Abrupt changes in cross sectional areas were the site of porosity in some specimens; also seen were small generalized areas of porosity unlikely to be disclosed radiographically.

D013499	Surface Properties	Characteristics or attributes of the outer boundaries of objects, including molecules.	Properties, Surface,Property, Surface,Surface Property
D015502	Absorptiometry, Photon	A noninvasive method for assessing BODY COMPOSITION. It is based on the differential absorption of X-RAYS (or GAMMA RAYS) by different tissues such as bone, fat and other soft tissues. The source of (X-ray or gamma-ray) photon beam is generated either from radioisotopes such as GADOLINIUM 153, IODINE 125, or Americanium 241 which emit GAMMA RAYS in the appropriate range; or from an X-ray tube which produces X-RAYS in the desired range. It is primarily used for quantitating BONE MINERAL CONTENT, especially for the diagnosis of OSTEOPOROSIS, and also in measuring BONE MINERALIZATION.
