Hello, I will be starting dental school this fall and Iheard that we need to collect a certain amount of teeth by the first quarter or something like that. Anyways, Ive asked all the dentists I have worked to collect extracted teeth for me, but thye asked me what percentage of formaldehyde I wanted to put them in. I looked like a jack a$$ coz I didnt know what to say. Any tips? Is there anything else ebsides formaldehyde I need to get? Thanks.
