Tooth Decay Curtailed by Use of Chemical
A report from Atlantic City notes preliminary tests by Naomi C. Turner and Dr. George Crowell suggesting tryptophane in saliva may influence tooth decay. Eight volunteers with cavities in six months split into treated and untreated groups showed possible reductions, but the small sample limits significance. Further comment from Dr. Fosdick emphasizes acid inhibition or saliva neutralization as decay control. related notes urge rheumatic fever prevention through school programs and report UV light reducing measles spread in a nine year Penn study.
