[Dental plaque pH in patients with hereditary fructose intolerance].

There is little doubt that the initial cariogenic attack upon dental enamel is caused by acids stemming from metabolic activity of dental plaque microorganisms fermenting carbohydrates. However, a direct correlation between caries activity and pH changes of plaque has not yet been established. In-vio and in-vitro plaque pH was recorded in 4 caries-free HFI children by the method of Graf, R., and Graf, H. Application of 10% glucose were followed regularly by pH drops from the fasting range pH 6.2-7.2) reaching values of 4.7 to 6.5 after 20 minutes. These were comparable to values found in normal subjects. 10% sucrose treatment resulted in a slower and less pronounced pH lowering, reaching a pH between 4.8 and 6.5 compared to normal control subjects, which showed the classical drop down to pH 4.0 to 4.3 The results indicate that human dental plaque grown under sucrose- free conditions cannot metabolize sucrose (or its initial breakdown produce fructose) to produce an in-vivo pH drop below the critical range of enamel demineralization. The zero caries activity of the children may be explained by the lack of a demonstrable classical pH drop or acid attack.

Comparison of dietary habits and dental health of subjects with hereditary fructose intolerance and control subjects.

Persons with HFI follow a lifelong, self-imposed, sucrose-restricted diet in which foods containing sucrose are consumed infrequently. Our subjects with HFI had a total sucrose intake that was approximately 5% that of control subjects and had a caries score (DMFS) that was less than 10% that of control subjects. No significant differences were found in the oral hygiene status (plaque or oral hygiene indexes) of the two groups. Foods containing starch, in the absence of sucrose, are not articularly inducive to caries. The daily intake of sucrose of the control group was less than expected. Consumption of sucrose is, therefore, less than estimates calculated by per capita sucrose disappearance. We consider that caries is initiated when the sucrose content of the diet and the frequency of ingestion exceed a low limit.
