Where I believe the design is deficient in this study is in the  
absence of infant formula as a comparator, especially infant formula  
sweetened with corn syrup.

Cows milk, cola, and honey drinks aren't breastmilk substitutes. So  
what is the study designed to investigate? What applications did the  
authors expect the study to have in clinical practice? The  
cariogenicity of non-nutritious sugar drinks is nothing new; all we  
know now that is new is that thawed, dead human milk is associated  
with caries in desalivated rats at a very slightly higher rate than  
cows milk.
