It seems that since the enamel that covers your teeth is the hardest substance in your body, the DNA in the pulp of the teeth therefore is the most well preserved and uncontaminated specimen. Also, tends to be there after other DNA has been disinigrated.

That is an interesting fact....hmmm.

Yeah, the expert said all DNA disinigrates to nothing after long periods of time. The skeleton of a 50 year past case they were after yeilded no nuclear DNA just as the iceman or any mummy would not have.
The phrase, "tooth pulp yeilds uncontaminated DNA" is what got my attention. Remember, "EVERY marker matched exactly?"
