To be stored with care
1- Indication
For dental use only, Neoniti files are intended for treating root canals as part of a conservative treatment and must be used by qualified
healthcare professionals:
Neoniti C1 n°25/.12 : orifice opener for flaring the coronal third of a canal
Neoniti GPS n°15/.03 (white): pathfinder to realise the glide path and check the canal patency
Neoniti A1 n°25/.06 (red): shaping file for the mesial and apical parts of a canal
Neoniti A1 n°20/.06 (yellow): shaping file for difficult canals (calcified, narrow, curved)
Neoniti A1 n°40/.04 (black): finishing file for a large canal
2- Precautions for use
• The only known adverse effect is the accidental breakage of Neoniti file, usually in case of inappropriate use. This risk can be reduced
by taking the following precautions:
- Evaluate the difficulty of the clinical case with a pre-operative radiograph.
- Always work in a root canal that has been permeabilized by a suitable pathfinder.
- Use the files in their strict intended use, with a contra-angle equipped with a torque control.
- Use a moderate force during the canal penetration.
- Thoroughly and regularly irrigate (every 3 passes).
- Regularly wipe the file (every 3 passes).
- Discard the instruments after use.
• Before use, please keep Neoniti files in their original packaging in a clean, and dry place and away from light.
• Neoniti files are provided non-sterile and are intended to be cleaned, disinfected and sterilised by the dentist before use.
• Do not sterilise more than 5 times.
• Do not use if the file or his packaging is damaged, or not correctly identified.
• The file of the right size must be selected by checking the ISO colour of the silicone stop, except for Neoniti C1 (no silicone stop).
• It is advised to use a dental dam to prevent accidental ingestion of instrument.
• Hydrogen peroxide damages the Nickel-Titanium files, avoid contact with Neoniti files.
• At the stage of cleaning and disinfection of the instruments, do not leave them immersed into a sodium hypochlorite solution.
• Avoid introducing Neoniti C1 too deep into the root canal.
• Wear appropriate personal protective equipment (gloves, glasses).
3- Warning
Neoniti files have a blade made of Nickel-Titanium alloy, do not use in case of known allergic sensitivity of the patient.
Neoniti files are intended for a single patient use. Repeated uses and sterilisations may unwind or affect the file, therefore it may weaken the
file. The use of a weakened file may lead to its separation.
4- Operative procedure
Use Neoniti files in continuous rotation at a constant speed between 300 and 500 rpm and a torque limit of up to 1.5 N. cm.
 Endodontic treatment
• 1
st
step
Realise the glide path and check the canal patency by using a GPS file or, by default, a K file of size #06, 08, 10 and then 15.
• 2
nd
step
Neoniti C1 is introduced into the canal at a maximum depth of 5mm.
The work is performed using a wall circumferential brushing motion onto the opposite wall of the curvature to widen and relocate the
canal orifice, aiming to ease the progression of the following instruments until the apex. Work under thorough and frequent irrigation.
• 3
rd
step
Measure the working length (WL) as soon as possible, with an apex locator and/or a periapical radiograph.
• 4
th
step
- Neoniti A1 is carefully introduced into the canal by 2-3 pecking and upward circumferential brushing motions from the bottom up.
- Rinse, check the canal patency with a GPS file or otherwise by using a K file #10 or 15.
- Clean the Neoniti A1 flutes with a sodium hypochlorite swab.
- Reroute Neoniti A1. If the WL can be achieved, only use pecking motions in the last 3-4mm at the apex.
- Rinse and check the patency.
- Clean Neoniti A1.
- Repeat the above sequence as long as the WL is not reached.
- Work under thorough and frequent irrigation.
 Particular cases
- The difficult, narrow or curved canals can be more appropriately treated using Neoniti A1 size 20.
- The larger canals can be completed using the Neoniti A1 size 40 finishing file.
