SECTION 7: APPLICATION OF ROOT CANNAL FILLING
First-Phase Preparation
1) Gutta percha point (Master cone)
Select the appropriate gutta percha point as a master cone which has same
taper and size with prepared root canal. Shorten 0.5-1 mm
of the point than
working length to avoid overfilling and to secure enough space to fill
additional point.
2. Hand plugger
Prepare 2-3 hand plungers to compact the filled gutta percha.
3. Pen tips
Select the appropriate pen tip and sign the working length by using callipers,
The signed working length should be 5-7 mm short than the length of root
canal and make sure the pen tip size will not touch the root canal.
4. Pen tips
Please select the appropriate size of pen tip according to the thickness at the
2/3 position of root canal coronal.
A.
Vertical Condensation/Down Pack
1. Dry the root canal, apply a thin layer of root canal sealer on the root canal
wall, and put the GP cone in position.
2. Confirm the working length, warm the selected pen tip and cut off excess GP
cone.
3. Put the gutta percha cone inside the root canal and then push it slowly into
the apex by using warmed pen tip until the pen tip is 5-7 mm from the apex
then stop warming the pen tip. (The whole process should be finished in 7-9
seconds)
4. Softly press the gutta percha cone for 10 seconds, warm the pen for 1
second again, and take out residual gutta percha cone. Compact the warmed
gutta percha by using the hand squeezing device.
5. If the root canals need to place the post pin, the backfilling process can be
omitted, leaving enough space for the post pin. If not, backing filling it with
obturation gun.
