Abstract
|
|
|
Objective: The present study aimed to assess the effects of consuming milk on inhibition of sugar fermentation through comparative analysis of cariogenic organic acids (lactate, formate, and pyruvate) produced in the mouth on consuming milk after cariogenic drinks.
Methods: The organic acids were analyzed by HPLC (GP50 gradient pump, ED 50 conductivity detector) after saliva pretreatment under isocratic conditions, using an ionex IonPac AG11-HG column (50×4 mm) and 120 mM NaOH mobile phase.
Results: The group that did not consume water or milk after cariogenic drinks showed the highest rate of organic acid production; lactate with cariogenic potential was detected to a higher degree in the group that consumed water than in the
group that consumed milk after cariogenic drinks.
Conclusion: Consumption of milk after sugar can play a role in preventing dental caries by causing a temporary pH buffering effect and inhibiting organic acid production by inhibition of sugar fermentation.
