You take 3 files larger than this.
Ex) If the tug-back file is 20k, you work it up to 25, 30, 35k and
a tug-back.
After hand-filing with 2 K-files at the working length, use
the largest rotary file and insert with gentle pressure for a
count of 3 until you feel the resistance.
If you reached the working length, you are done!
(If not use the next smallest rotary file until you reach the
working length.)

Endo Files
K-Files
Nickel titanium is more flexible and better to use for curved canals
Stainless steel files are more rigid and need to pre-bend when
working on a curved canal to prevent perforation (making your own
new canal).
Reaming and Filing- two ways to clean and shape RC with K File:
Rotary Instruments
Advantages:
Disadvantages:
Expensive
Unexpected fractures
Navigating curved canals without first using hand instruments can cause
Gutta Percha
Coated with cement and inserted into the canal space to make up a
root canal filling
Gutta percha used in preclinic are non-standardized and come in
five sizes: fine-fine<medium-fine<fine<fine-medium<medium
As many cones as possible should be squeezed into the canal
space for a dense and air- tight fill
During obturation, the canal is filled with gutta percha and this
instrument is used to laterally condense the gutta percha

RC Prep
Indications
When there is
insufficient coronal
structure for the
retention of a
restoration
Need to use a post
which holds in place
the core, which is
used to build up
tooth structure
Post preparation
Post preparation weakens the tooth, and makes it more likely to fracture
Ready made dowels which you can immediately insert into the prepped
post space can be completed in one visit, vs. two for custom
Can be used in multirooted teeth, where you place two non-parallel to
each other to lock it in place
Custom fabricated or
cast post & core
Core build-up
Ferrule Effect
E.g. if you hammered a nail into the end of the stick, the ferrule protects the
sides and prevents it from splitting
A tooth needs the same protection from the post, which acts as the nail in
this situation
The apical most portion of the crown acts as this ferrule (you need at
least 1.5 2 mm as a ferrule)
So the crown has to end at least 1.5 mm apical to where the core ends!
