My tuppence worth.......decal in EDTA at 37C ( change regularly as EDTA
chelates Ca++)and use Xray or a chem test, once you've liberatred the Ca++
from EDTA ( hence "sequestrene") OR use Formic acid or, better,
Formic-formate and chem test for Ca or Xray. If it's purely for histological
examination, mineral acids are fine but use at5%. We always found it better,
where possible, to bisect the tooth longitudinally , before decal, using a
special cutting apparatus but.....hey! that costs.Any problems we had were
always found to be due to inadequate processing or blunt knives.
