I'd sure appreciate some tips in how to find more 4th canals. 
- Larry Levin - Hamilton ON

The attached images were taken using a Nikon Coolpix 950 on an Optique
microscope using a xenon light source.

Notice that image #5 is a bit cloudy.  I turned down the scope light
to see the effect it would have on the image and it was a tad dark so
I lightened it in Photoshop.  I should have sized the images larger.

This is tooth #15 that I treated yesterday.  I found four canals in
100% of the 2nd molars I treated yesterday.  Of course, I only treated
one 2nd molar yesterday! - Bill Watson
