Strange lines in viewport render ortho, but not camera view

I started modeling some teeth and noticed something I never have. When I do quick renders in user ortho there are lines everywhere. The lines do not appear in camera view viewport renders, or in final renders. What is this? 2.68a (2)

Try changing your camera clipping limits. I’ve seen that affect it before.

Changed start to .001 and they went away. Thank you.
