RE: cutting teeth

From:"Dunn-Jena, Patsy Ann"


We have done this in the past for some of our projects, but it has been
several years.  We normally take a pre-decaling x-ray and then a post x-ray
to compare starting at week 3.  Have also used a needle to check.  Depending
on the EDTA recipe used and the age of the animals, it will take from 4-6
weeks for complete decalcification.
