Two recent cases.
Comments and criticism welcome - Nuria Campo
which files do you use to negotiate the canals?
c-files? and do you use any edta paste? - Gary Wu
I use K-Files 6 - 8 -10 (Dentisply-Maillefer)
21mm in order to have a little more finger touch
sensation + Glicerine like lubricant.
I tried s.t. C+ but in my hands they are not very
useful, but actually they are designed for this cases.
IMO use Edta in this cases could be even worst,
because Edta is not Ca+2 selective, in other words
it softens Reparative Dentine (that closed the
original RC path) but also Primary and Secondary
Dentine (RC walls one). In conclusion, you will
increase the risk of perforation.
I recommend to read this former paper and visit
Rob Kauffman case reports.
- Ngeow WC, Thong YL. Gaining access through a
calcified pulp chamber: a clinical Challenge.
Int Endod J. 1998 ;31:367-71.
A Scope allows to read the Dentin Map and
Munce burs are the keys but even w/o you can manage
some of this ones.
I have never used Munce burs. Does s.b. say which
are the most used diameters (1/4,1/2,1,2,3 or 4)?
Which one for this cases?
Which ISO diameter have each one? - Nuria Campo
Really enjoyable cases here. I use HERO Shaper
rotary-NiTi-system for preparations and occasionally
Torpan burs for removing old fillings in retreatment
cases, also sometimes in calcified canals.
Any comments on these ? Greeting from
