Ok folks:  I wanted to share with you one area where the diode laser helps.  
This patient is a lawyer, I have never seen her before.  She just left.  
She cracked a tooth (lower 2nd molar) on a chicken bone.
She never flosses.  The tooth was sore to chewing and she wanted the crown 
done today.

You can see these quick photos taken from my Sony HD video camcorder of the 
case.  The crack was large and I advised her that she may likely need an
endo but she wants to try without it first.

Since she never flosses its tough for me to use cord.  The bleeding is alot.  
So I used the laser and troughed to get the impression .  
It took me 2 mins to do this.

No viscostat, no cord, no problems - Glenn

Glenn,,  In many cases I believe 80%, a composite filling would do in cases 
like this. Just by taking amalgam out and placing a composite filling, 
you  don't have to remove the crack's just fill it properly
and the pain will disappear. -  Rob

Rob......interesting viewpoint......

This patient wanted a crown, and this was already a very deep MOD and both 
lingual cusps were cracked . I am sorry but in my practice I do crowns and 
often these end up needing endo as well.

This is a crown for sure in my practice ( 3 surface MOD + fractures of both 
ML and DL cusps).  You could do an onlay I guess but I wont do a 4 surface 
resin on a molar like this very often

The ML cusp broke off half way through as well.

Sorry, this one needed cuspal coverage for sure and the patient was sore 
as well. - Glenn

Here are two views of the cracks....I  have found that most of these will 
not settle down when I do a resin and if so its only provisional. 
Just my viewpoint. - Glenn
