Abstract
In addition to being co-discoverer of the antibiotic streptomycin the American microbiologist and soil scientist, Albert Schatz did ground breaking dental research. His major contribution is the Proteolysis-Chelation theory, but he also did research on fluoridation where he emphasised the overlooked involvement of so-called paradoxical effects. His research led him to become an active supporter of anti-fluoridation campaigns. The following article discusses Schatz's important and largely overlooked contribution to dentistry.
