Subject: [roots] Core versus Hole

I try to get my referrals to let me do the cores by showing contrasting 
examples like this.  I treated the lower second molar on this patient 
7 months ago.  She came back for another tooth with an interesting photo 
view of the core I placed last July versus the core done by someone else 
on the maxillary molar.   You can see both teeth in the photo view, 
one with the mirror reflection and the other directly viewed (with a bit 
of saliva). :)

It's also a good photo to have in your patient education series when a 
patient asks why their previous dentist did the core for free :):):):)

Very nice work Terry! May I ask what materials you use for the core 
build up and your step by step process? - Jonathan

I learned this from Ron Fransman.  I build up the internal core with 
Clearfil Photobonded Luxacore, then placed the surface with Filtek 
(shade match) then slightly tint with 6 endo file (brown tint) and use 
a brush to smooth. If the porcelain is thick they usually look really 
good,  If the porcelain is thin, not so good.  I'm finally getting 
pretty good at recognizing plunging cusps and looking the existing 
anatomy ahead of time to figure out how to not build it too high.  
Taking a quick photo of the surface before you access the porcelain 
is a pretty good idea if you remember.  Sometimes I start accessing 
the case, then think, "Damn, I forgot to get a prephoto" :)

Ron and Marga are masters and mastresses at this,  I'm always trying 
to get better on the next case.  :) - Terry
