Safety Reciprocating Endo Files NITI M-wire ISO Red with CE and FDA For Cyclical Endodontic Retreatment
Description:
Reciprocating system of Reciprocating file also known as single
file,which processed by new nickel-titnium material,non blade of
the safety circular apical,file needle with flexibility,better
anti-fatigue ability for cyclical use,more safety in clinical
operation.
Specifications:
| Size | Taper | Torque | Rotary Speed Range | ISO Color | Using Times |
| R25 | 0.08 | 3.55 N/CM | 250-350 RMP | Red | 8-10 times |
| R40 | 0.06 | 3.55 N/CM | 250-350 RMP | Black | 10-12 times |

Competitive Advantage:
Preparation the root canal with single file,convenient and quick;
Less working steps,more efficient and less time-consuming;
Suitable for curved and narrow root canal preparation;
New Niti material enhances the flexibility and ability of
anti-fracture;
Three sizes are available for different types of root canals.
Operation Sequence:
In most cases, the R25 will be suitable in size for the root canal
treatment. Consult the pre-operative radiograph to see if the canal
is likely to be considered as narrow, medium or wide.
If the canal is partially or completely invisible on the
radiograph:
The canal is considered narrow = use R25.
If the canal is completely visible on the radiograph:
1.Take an ISO size 30 hand instrument; insert it passively into the
canal. If it reaches working length, the canal is considered large
= use R50.
2.If an ISO size 30 hand instrument does not go passively to
working length, try an ISO size 20 hand instrument. If this goes
passively to length, the canal is considered medium = use R40.
3.If a size 20 hand instrument does not go passively to length, the
canal is considered narrow = use R25.
Passively means that the instrument goes directly to working length
without any watch-winding and can be moved up-and-down without
filing action.
The amplitude of the up-and-down movement should be 4-5 mm.
Preparation with the R25 – Getting started:
Prior to preparation with an R25, estimate the working length with
the help of a pre-operative radiograph. Set the stopper at 2/3 of
that length.
Preparation with the R40 and R50 – Getting started:
Before selecting the appropriate RC File instrument, check the
working length electronically by using K-file. Set the stopper at
that length.
