Treatment protocol followed
*Basic Protocol
1.Administration of local anaesthesia was
done.
2.Isolation of working field was established
using a rubber dam & liquid-dam.
*Root Canal Access cavity Preparation(RCO)
3.RCO done with Round bur & refinement was
done with ENDO Z bur(Dentsply).
4. Working Length was recorded via EAL –
electronic apex locator (Root ZX J Morita)(All
Canals).
No Steady Reading for distal canal (sign of
resorption/open apex)
confirmed with iopar.
Patecy was achieved with 10k
File should be super loose before proceeding to
next file
Glide Path ONE G(micromega)till working
length (W.L.)
Note: 5.25% SODIUM HYPOCHLORITE
should always be present in the chamber during
filing.
After achieving the desired Glide path, switch
on the Rotary file & the sequence was
FOR MESIOBUCCAL AND MESIOLINGUAL
CANALS:
Two shape TS1 2504 (3 wave technique)
FOR DISTAL CANAL:
Hyflex cm 2004>2504>3004>3504>4004
Note: Don't forget to recapitulate with 10 k hand
file in between subsequent filing sequence
along with continuous irrigation with Sodium
hypochlorite
*Irrigation Protocol
fig 2
Mesial canals:Positive pressure irrigation
technique (30 gauge Needle side ventral-
syringe)
Distal canal:Negative pressure irrigation
technique(metapex thin tip at the apex to suck
irrigant to prevent extrusion from canal to
periapex)
5.25 % Sodium hypochlorite(CERKAMED) –
activated with sonic tip (dentsply endoactivator
tip in waterpik flosser)
*Shaping Protocol
Coronal flaring by using Oneflare (Micromega)
Working Length by electronic apex locator
(EAL)
Note: Pulp chamber should be dry and canals
should not be dry to get accurate results from
EAL
Cross checked and confirmed with IOPA
radiograph
23
1 7 % E D TA l i q u i d ( S M E A R C L E A R
Symbronendo)– 1ml for each canal –activated
with sonic tip.
Normal Saline wash in between two irrigating
solutions.
Master cone IOPA radiograph was taken.(figure
3) and mesial cone adjusted later on during
obturation.
