The document discusses the advancements in endodontic treatments using rotary nickel titanium and introduces the SAF (Single-file Adaptive) system, designed to enhance cleaning and shaping of root canals, particularly oval ones. The SAF employs a hollow compressible Niti file that minimizes unnecessary dentin removal while ensuring effective disinfection and obturation. The system includes specific devices for irrigation and operation, providing economic advantages and improved clinical outcomes in dental procedures.

3. Rotary nickel titanium were first introduced
clinically in 1993 in represent a real shift in
endodintic
New design have been introduced over the years
attempting to make these instrument more
efficient, more flexible and safer in the term of
file seperation

4. Current rotary file systems are effective tools.
Nevertheless they have two main
shortcoming:-
A- They are unable to effectively clean and
shape the oval canals and depend too much on
irrigant to do cleaning
B- The long term survival of the tooth is by
unnecessary excessive removal of dentin and
creation of microcrack
Current rotary file systems are effective tools.
Nevertheless they have two main
shortcoming:-

B- The long term survival of the tooth is by

5. Is a shaping and cleaning system designed
for minimally invasive endodontic
treatment

6.  The new SAF technology uses a hollow
compressible Niti file, with no central metal
core , through which a continuous flow of
irrigant is provided

8.  The SAF has lattice like design makes the
instrument extremely flexible in all three
dimentions to fit the cross section of the canal
at any vertical location

10.  The SAF is the first file that does not have a
solid metal shaft is designed as a hollow tube
with rough outer surface

13.  This technology uses a new concept
of cleaning and shaping in which a
uniform layer of dentin is removed
from the root canal thus avoiding
unnecessary excessive removal of
dentin

14.  The SAF allow for effective cleaning of all
root canals including oval canals, thus
allowing for effective disinfection and
obturation of all canal morphologies

18.  The SAF is avaliable in three standard
lengths (21mm,25mm,31mm) and two
diameters (1.5mm,2.0mm)

20. 1- SAF System:- include the VATEA
peristaltic irrigation device and RDT hand
piece

21.  RDT hand piece operates the SAF with
0.4mm amplitude vertical vibration and
designed to be operated at 5,000 rpm

22.  RDT hand piece heads the only hand piece
that provide the combined motion of vertical
vibration and rotation required for proper
operation of SAF

23.  The RDT hand piece is designed to sustain
prolonged exposure to sodium hypochlorite

25. The VATEA system is a self contained fluid
delivery unit intended to deliver irrigant
solution during endodontic procedure

26.  The irrigant is delivered via a disposable
silicone tube
 The flow of irrigant toggled by using a foot
pedal and the operator can adjust the flow rate
by using -/+ push buttons

28. 2-SAF proSystem:- include the endostation
endodontic motor
The Endostation is a multi functional
endodontic motor that enable the user to
operate various endodontic system including
SAF and all major brands of rotary and
reciporcating file

29.  The Endostation include peristaltic pump and
irrigation system
The irrigation system are operated by foot
pedal

30.  A large LCD screen and audio are used to
indicate the flow rate , working time and
battery status

35. When comparing with other rotary system there is
economic value thanks to the SAF because of
the additional clinical benefits including
avoidance of post operative pain, highly
efficient endo treatment, the ability of improved
cleaning and disinfection in short time with less
risk and less complication
