A new electronic system was set up for accurately regulating the amount and frequency of food dispensed to laboratory rats so that investigations of the cariogenic potential of foods can be carried out under strictly controlled conditions according to the stipulations of the San Antonio Consensus Conference, 1985. The system was used to evaluate the cariogenicity of sucrose incorporated into plain and milk chocolate. The results suggested that 18.75% of sucrose in the diet had the same cariogenic potential no matter whether it was in the form of fine crystals or incorporated into plain chocolate, but mean caries scores were nearly 30% higher on a plain chocolate than on a milk chocolate regime.
