Plaque accumulation and characteristics were determined gravimetrically, planimetrically, visually, and microbiologically in 24 human subjects who consumed a carbohydrate-free diet for 4 days. In addition, the effects of xylitol-, sorbitol- and sucrose-containing candies upon plaque formed during
The activity of enzymes releasing glucose and reducing sugars from sucrose, maltose, starch and dextran was compared in the same pooled samples of plaque fluid (PF) from 24 h human dental plaque. Equimolar amounts of glucose and fructose were released from sucrose in 3 h incubations. Reducing
Carbohydrate analyses were performed on dental plaque collected from the teeth of irradiated monkeys, non-irradiated monkeys and a group of Streptococcus mutans free animals, all of which were fed the same standard cariogenic diet. Glucose was the predominant sugar constituent in plaque and was
The carbohydrate to protein ratio of dental plaque was analyzed in a field study assessing the effect of partial substitution of dietary sucrose by xylitol (X group) in comparison with systemic fluoride (F group) and restorative treatment solely (C group). The biochemical analysis was supplemented
In general differences in plaque composition between anterior and posterior teeth have been reported. Dental plaque from the upper lower anterior teeth shows differences in bacterial composition and pH. Results showed that plaque from lower anterior teeth contained less alkali soluble polysaccharide
