Subject: [roots] carious exposure

Nice to get a carious exposure once in a while.  Difficult access and
lots of caries,  but a decent result. Respect for ID canal in apical
preps,   I held handfiles in tweezers here due to limited opening.  Pt
must have been 300 lbs,  and had the cheeks and tongue to go with it,
hence the poor rad which he managed to move in the holder.

Terry would have not have started this,  opening of 30mm max :-) -  Bill



Great result Bill!! What's instrumentation sequence and the master apical file for this case?
Just for learning ;-) -  Maurício Basso

Mauricio , I used hand file 10 -30 in tweezers to just open things a little.  Then
gates 2-4.  then hand files again,  then gates again.

then I used EAL and took hand files to 30 to within 1mm of EAL 0.

Then I finally put some rotaries in there,  Pro TAPER,  S1 - f1 at eal 0.5, then F2 at eal 1.0
and F3 back from this about another 1/2 mm.  So master apical file will have been a 25,  but lots
of curved files at this level,  hence the larger " look "  on the film.  I didn't want to
be long due to the proximity of the canal,  but was patent in all canals - Bill

Beautiful work.  Especially amazing considering the working conditions.- Huq

Awesome worK, this patient was lucky staying in your hands.

I just discover this tool (see pics) in Amsterdam University (ACTA). I think it could be useful in
this case instead of tweezers, and you can try have indirect vision - Nuria from Barcelona





Thanks Nuria , Do you know the name of it? - Laura

Hi Laura , Sorry , but I don´t know the name. I think that is an older instrument, and you can even cut
the file handle for improve índirect vision in limited mouth opening cases... just useful for radicular
access in my opinion - Nuria
