Do schools verify shadowing hours?

I'm still a while away from applying but I was wondering if schools verify shadowing hours. I've only shadowed a couple hours so far and while the dentistry is awesome, the actual shadowing sucks since you're just standing around. Obviously I don't intend to only do 10 hours and say I did 100 or anything like that, I'm asking because I might round up a little bit.
