fructose/dental caries

This study was undertaken to investigate and compare some biochemical and physiological properties related to sugar metabolism of 4 laboratory strains and 13 freshly isolated strains of Streptococcus mutans from carious and caries-free tooth surfaces and from subjects with hereditary fructose

The purpose of this study was to quantify the changes in the size of approximal caries lesions during regular sucrose or fructose consumption. The material consisted of the subjects in the 2-year Turku Sugar Study, with an observation period of 19 months. Planimetric evaluation showed a highly

The purpose was to study differences in the caries increment rate as influenced by various sugars. The trial involved almost complete substitution of sucrose (S) by fructose (F) or xylitol (X) during a period of 2 years. There were no significant initial differences as to caries status between the

The effects of AMP and fructose 2,6-bisphosphate (Fru-2,6-P2) on porcine fructose-1,6-bisphosphatase (pFBPase) and Escherichia coli FBPase (eFBPase) differ in three respects. AMP/Fru-2,6-P2 synergism in pFBPase is absent in eFBPase. Fru-2,6-P2 induces a 13° subunit pair rotation in pFBPase but no

A slightly irregular, short rod-shaped bacterial strain, MOZIV/2T, showing activity of fructose 6-phosphate phosphoketolase was isolated from the oral cavity of a home-bred guinea-pig. Based on comparative 16S rRNA gene sequence analyses, its closest relatives were Alloscardovia omnicolens DSM

The cariogenicity of fructose, sorbitol, and xylite in chocolate bars as against that of sucrose was tested by ad libitum and programmed feeding of rats. After both types of feeding, the sucrose-containing feed showed the strongest cariogenicity and the xylite-containing feed the weakest

Fructose 1,6-bisphosphatase (FBPase) is known to form a supramolecular complex with alpha-actinin and aldolase on both sides of the Z-line in skeletal muscle cells. It has been proposed that association of aldolase with FBPase not only desensitizes muscle FBPase toward AMP inhibition but it also
