|STEP 1: ACCESS, FLARING, WORKING LENGTH, CANAL PATENCY|
After making access, prepare the coronal third of the canal with Gates Glidden drills
or the instruments of your choice. Obtain working length and establish canal patency.
|STEP 2: INSTRUMENT THE APICAL PART OF THE CANAL AND DETERMINE WORKING WIDTH|
When using LSX™ Rotary Instruments for apical instrumentation, remember to
always slowly advance the instrument apically. When resistance is felt, pause,
then proceed to Working Length. This technique is simple: 1. Advance to Resistance,
2. Pause at Resistance, 3. Proceed Slowly to Working Length. Your Final Apical Size (FAS)
is the instrument that encounters resistance 4mm (or more) from Working Length.
|STEP 3: COMPLETE APICAL SHAPING|
Using the same technique as in Step 1, instrument to 4mm short of Working Length
with the next larger instrument (than the FAS). This shapes the apical 5mm and
prepares the canal for a matching SimpliFill Obturator.
|STEP 4: INSTRUMENT MID-ROOT|
Instrument the mid-root with sequentially larger LSX™ instruments. Advance to resistance,
pause, then push 2 to 3mm apically with each instrument. DO NOT advance any mid-root
instrument into the final 5mm from Working Length at this point in the procedure.
The mid-root technique is simple: 1. Advance to Resistance, 2. Pause at Resistance,
3. Push forward 2-3mm apically but do not proceed to within 5mm from Working Length.
Mid-root instrumentation usually requires no more than 3 instruments.
|STEP 5: RECAPITULATE|
Using the FAS rotating in the handpiece, recapitulate to Working Length.
|STEP 6: FINAL IRRIGATION|
Irrigate with NaOCL, then ED TA, then NaOCL again to clear the dentinal tubules.
Finally, irrigate with Chlorhexidine. See the EndoVac irrigation system on page 12
for more information on effective irrigation techniques. Once you have confirmed that
the canal is clean, dry, and free of debris the canal is ready for obturation.
