An investigation of the effects of maltose and sucrose in the diet on the microbiology of dental plaque in man.
In a double-blind cross-over study, 24 dental students consumed 150 g of sucrose or maltose a day in various foods. After 15 days, plaque samples were collected from the distal surface of upper right first premolars; post-diet samples were collected four months later. The median total anaerobic count of plaque exposed to sucrose was significantly lower compared with maltose samples (p less than 0.05). Glucan-producing organisms per 100 anaerobes in the sucrose samples compared with the maltose (p less than 0.05). Streptococcus sanguis and Streptococcus mitior were the most frequently-isolated streptococci.
