Jan,

     The news article at the web site:

     http://www.abcnews.com/sections/living/teeth1021/index.html

     has a paragraph which states:


          "An animal study in last month's Journal of the American Dental
          Association indicated that 2 percent milk posed the lowest dental
          decay risk. Infant formulas were somewhat higher, but still
          dramatically lower than any drink containing sucrose. "

     Not much info to go on, but it does suggest study (on animals?)
     results recently published in September's Journal of the American
     Dental Association.
