DENTAL PROPERTIES OF ANTISEPTIC THROAT LOZENGES FORMULATED WITH SUGARS OR LYCASIN

Thirteen different formulations of throat lozenges were examined for t heir acidity, demineralizing action on hydroxylapatite, and fermentabi lity by human dental plaque micro-organisms, Their flavouring acids ga ve them low pH values in the range 2.6-3.7, leading to the dissolution of calcium and phosphorus from hydroxylapatite. The combination of an tiseptics and flavouring acids in the lozenges inhibited microbial gro wth and metabolism. In the absence of any antiseptics and flavouring a cids, the growth and metabolic activity of cultures of plaque micro-or ganisms were significantly greater on sucrose + glucose lozenges than on a new Lycasin formulation.
