MicroCycle 3: NaOCl, MDT, 20 cc Syringe, MicroCannula, 30 seconds
active, passive 60 seconds.
1. Place MicroCannula to full WL and deliver NaOCl from MDT for 10 seconds. Stop delivery and watch for
MicroCannula to suction (purge) all NaOCl from the canal.
2. Repeat previous step for another 10 seconds.
3. Repeat again, but after delivery for 10 seconds remove the MicroCannula immediately before removing the
MDT, leaving the canal filled (charged) with NaOCl.
4. Let the NaOCl work for at least 60 seconds before proceeding to the next step. While waiting, fitting of
a gutta-percha point is optional.
Dry Canal: MicroCannula, Paper points.
1. Place MicroCannula to full WL for at least 3 seconds.
2. Confirm canal is dry or continue drying with paper points.
8. Troubleshooting
Unclogging the Cannulae
Correct use of MacroCannula to remove the gross debris will minimize MicroCannula clogging. Once the
clinician gains proficiency in clinical use, clogging becomes a non-issue and happens infrequently. If either
cannula should become clogged, try unclogging it by attaching the back end of either the Fingerpiece or
Handpiece onto a syringe filled with water. Push the plunger and in most cases the hole(s) are immediately
cleared, as noted in (Figures 24 and 25).
Retreatment
In the case of retreatment, all pulp canals must be fully prepared, cleared and dried of gutta percha solvent as
much as possible before proceeding to both Macro and Micro evacuation. Still, clogging may occur as this is
the very nature of retreatment. When this occurs, unclog as noted above.
In anticipation of excessive clogging during retreatment, adequate clearing of the canal before evacuation
reduces the chances of
this happening.
Failure to Initially Draw Irrigant
Failure to achieve Micro flow can occur if the MicroCannula is taken through the foramen. If any of the Micro’s
twelve (12) holes extend beyond the apical foramen, they will not draw irrigant. If the clinician experiences
this, withdraw the MicroCannula 0.5 mm at a time until flow starts.
9. Cleaning & Sterilization
WARNINGS • All re-usable components must be cleaned and sterilized prior to each use.
• Failure to properly clean the components could lead to inadequate sterilization.
• Only use cleaning solutions tested for efficacy and compatibility with the device /
equipment being used.
• Always observe all applicable legal and hygiene regulations for practice and / or
hospital.
• Always wear protective gloves, glasses and a mask when handling contaminated
instruments.
Limitations on
reprocessing • Repeated processing has minimal effect on the Aluminum Handpiece, Finger-Piece
and Multi-Port Adapter; end of life is normally determined by wear and damage
due to use.
• For the Master Delivery Tip (MDT), it is recommended that the tip be replaced after
10 cycles in the autoclave. Replace the MDT earlier at any signs of wear or damage.
• Cold liquid disinfection/sterilization, chemical vapor sterilization, and dry heat
sterilization methods have not been tested or validated for efficacy and are not
recommended for use.
INSTRUCTIONS
Point of use: • Following use, components should be reprocessed as soon as is reasonably
practical.
• Components that may be processed for re-use include the Aluminum Handpiece,
Aluminum Finger-Piece, Aluminum Multi-Port Adapter and the Master Delivery Tip.
• Micro and MacroCannnulas and evacuation tubing must be removed from
autoclavable components before reprocessesing. These items are single use only
and should be discarded to prevent cross-contamination between patients.
• Remove excess soil by wiping components with a disposable wipe and/or running
under tepid (potable) water, checking for signs of visible contamination. Dry
thoroughly with a disposable wipe.
