I'm hoping that this isn't as painful as the actual process we all
went through as children. I'm told that one of the investigators here
will be sending a couple hundred teeth to my lab soon. I have never
processed or sectioned teeth before so I'm hoping that I can find a
few good suggestions on histonet.
Here is what they are doing - based on two papers from JOE in 05 and 07:
Fixation is in 10% NBF - how long do you fix teeth? Is temperature
something to consider here?
Decalcification is done in a solution of equal parts of 50% formic
acid and 20% sodium citrate. The papers say 10 days is enough to
decalcify teeth. Is it enough time?
Following decal they infiltrated the teeth using "Skinner's method".
Anybody know what this involves? One paper says Methyl salicylate was
used as a clearing agent. Why is this better than traditional
processing on my VIP using Clear Rite 3 as a clearing agent?
In the papers the teeth were embedded in Paraplast and sectioned at 5
microns and then thinner, they actually want thinner sections - like
2 microns. We are looking for pulp tissue.
Then they want a Brown and Brenn stain and maybe a trichrome.
Thanks,
Andi
