dental caries threshold of 5.5.
This range suggests that enhanced enamel dissolution results from effects other than simple beverage pH, most likely the additives within non-cola beverages that are necessary for achieving the desired palatability,according to the authors.
Polybasic acids could maintain tooth surface pH well below the 5.5 threshold even with marked dilution, they added, and were thusvery aggressive towards dental enamel.
