Description:
Operation Sequence:
1. Open the crown: Taking X-ray film before operation, dissecting
shape of root canal , evaluating working length, open the crown to
establish straight pathway for dental treatment.
2. Smooth the root canal: Using 10 # K file directly determination
the root length if it could, and then preparation to WL smoothly
with hand file 15 # .
3. Root canal preparation: Flushing the canal with sodium
hypochlorite then use EDTA to preparation:
(1) Using One file preparation of 2/3 canal apical narrow area,
slightly pull up and down. After that exploration by using 10 # K
file .
(2) Using One file preparation of -3mm part apical narrow area ,
preparation without pressure,then exploration by using of 10 # file
.
1. Access Cavity Preparation
a) Take a preoperative radiograph to assess canal anatomy and
establish Estimated Working Length (EWL)
b) Establish straight-line access preparation to expose canal
orifices.
c) Remove coronal constrictions with burs(or use current flaring
technique). Canal penetration of burs is limited to 3mm below the
pulp chamber floor.
d) Irrigate thoroughly with sodium hypochlorite.
2. Establishing the Glide Path
Prepare the glide path using #10 Stainless Steel K-type hand file.
(for example MMC 10)
If the #10 K file easily reaches the EWL and if it is possible to
take a #15 K file down to this EWL: Copiously irrigate the canal
and use Mono file according to the established protocol.
3. Shaping the Root Canal
Irrigate thoroughly with sodium hypochlorite.
Place One file down to the 2/3 of the WL using an in and out
movement without pressure. Perform an upward circumferential filing
movement in order to pre-enlarge the canal.
Withdraw the One file instrument into the root canal and clean it.
Irrigate and check canal patency with a #10 K file.
Reintroduce the One file instrument into the root canal and place
it dowm to 3mm from WL using an in and out movement without
pressure.
Withdraw the One file instrument into the root canal and clean it.
Irrigate and re-check canal patency with a #10 K file.
Reintroduce the One file instrument into the root canal and take it
dowm to the WL by performing the recommended in and out movement.
The WL can be reached in one or more passages(file withdrawal,
cleaning of the file, irrigation and patency check) depending on
the complexity of the canal anatomy. An upward circumferential
filing movement can then be performed if necessary and according to
the root canal anatomy.
Remove and clean the instrument and irrigate the canal when apical
resistance or a slight apical pull is encountered Repeat steps
until the WL is reached.
