The cariostatic effect of calcium sucrose phosphate in a group of children aged 5-17 years. IV.

. A preliminary report .on the planning and establishment of a clinical trial of the efficacy of calcium sucrose phosphate, in the form of a food addltive, as a cariostatic agent was published in 1967(1 ) .. The results after one year indicated reductions in the dental· caries increment for all children in the ages 5-17 years. A further report published in 1968(2) covering the results observed after two years showed "an overall reduction of 25 pe� .cent in caries increment in the mouths of children eating the treated food and this reduction is mainly demonstrated in the proximal surfaces of posterior teeth which show more . than 50 per ce�t; less caries".
