Just for the point of it, if the regs say 100ml, thats volume. 105g is mass. Water SG=1.0 toothpaste is quite likely 1.5 (I am not that bored that I have weighed a known volume of it), so in reality you probably have every right to take a full tube of 105g toothpaste.
If you look at the DOTARS website, it actually says containers must be less than "100mls/grams".
Nice try though. Bet a lot of security people have nice clean white teeth now.
