A Relationship Between Dental Caries and Saliva

A Relationship Between Dental Caries and Saliva

“…Revised by authors, October 2, 1944 2. Since the publication of our brief note in Science (2) a note from Dr. H. J. Florestano has called to our attention his interesting study along this line made in 1938(3).…”

“…In carrying out these studies on hydrolysis, the authors had before them no previous reports of investigations of this type. 2 In the hydrolysis of starch, as indicated under standardized conditions by the spot-test disappearance of starch-iodine blue, saliva associated with severe caries acts rapidly. Individuals without caries produce saliva which hydrolyzes starch only slowly.…”

Caries‐susceptibility Tests

“…As pointed out earlier, this correlation coefficient should be in the range of 0.9 to 1.0 for the test to be useful on an individual basis. (Karshan, 1936;Swerdlove, 1942;Turner & Crane, 1944;Schmidt-Neilsen, 1946, 1947Stralfors, 1950;Sullivan & Storvick, 1950). T h e acid-buffering capacity of saliva has been investigated a s a caries activity test by a number of workers.…”

“…Saliva is incubated a t 20 or 37°C in the presence of starch. Residual starch is determined by spot tests (Turner & Crane, 1944) or, colorimetrically, by the production of a blue starch iodine complex (Claycomb et al, 1956). Enzyme activity has also been measured by the release of glucose (Hess & Smith, 1948 Claycomb et al, 1956;Snyder et al, 1962;Snyder etal., 1963).…”
