ENDO basis
Treat pulp and periapical diseases
Endo treatment (root canal) should be performed in
case of:
- Pulp necrosis or irreversible pulpitis
- Vital pulp
(but poor prognosis of pulp vitality, high risk of pulp exposure during
the coronal restoration, root amputation or hemisection)
Contra-indications:
• Patient with high risk of infective endocarditis
• Tooth with no functional future (wisdom teeth)
• Tooth with inadequate periodontal support
Endo Basis
Techniques comparison
Manual technique
+: Tactile sense
+: less risk of perforation (NiTi)
-: Numerous files are needed
-: Time consuming
-: Access difficulties (posterior areas)
Rotating technique
+: Fast canal preparation
+: Auto-reverse
- : Fatigue of the files
Reciprocity technique
+: Few files needed (1hand file + 1 mechanical file)
+: Same movement as manual (F+R)
+: Secure (less breakage, less apical pressure, etc)
Endo basis
Canal morphology varies
Curved / straight
Large / Small
Long / short
To fit all canals, files present
different shapes:
Different length
Most popular length:
21mm, 25mm, 29mm
Other: 15mm, 19mm, 23mm
The canals’ common feature is
their taper
Prepared canals: Taper 10 % in
coronal area, 2 to 4% in the
apical zone
Different diameters (ISO)
Ø15
Ø20
Ø25
Ø30
Ø35
Ø40
Different tapers
4%, 6%, 8%, 12%
Radial-landed (Smooth)  ex.
ProFile (Dentsply), HERO
(Micro-Méga)
Different files shape
+ Clockwise and counterclockwise
cutting edges
Straight edges (Cut)  Ex.
ProTaper (Dentsply),
RaCe (FKG), Sequence
(Brasseler)
Other shapes
Ex. EndoEZE AET (Ultradent)

Calibration
Controls the contra-angle’s
mechanical inertia for a perfect
micromotor/contra-angle match.
Repetitive sterilizations and contra-angle wear can lead to a lack of precision.
This function accurately measures the properties of the micromotor and contraangle handpiece prior to use for exact values.

STOP, AR, SAR
Parameters selection
Rotating
Beeping sound notifies user when 75% of the preset torque has been
reached and when preset torque limit has been exceeded.
STP - “STOP” Autoreverse
Stops without reverse rotation.
AR – “Standard” Autoreverse
When file reaches the set torque value, the
motor runs reverse until the motor has been
stopped. Next start will be in Forward.
SAR – “Special” Autoreverse
When file reaches the set torque value, the
motor runs reverse until the file is freed and
Automatically returns to Forward.
Rotating movement
Between X and Y, the torque is
increasing progressively until
MAX value
Microprocessor analysis
The time from « x » to « y » must be as short as possible
(less than 1/1000 sec. )

Switching from Rotating
to reciprocating
For micromotor/ contraangle match
Select the contra-angle
ratio (1:1 ; 6:1 ; 8:1 ;
16:1 ; 20:1 ; 32:1)
Select the speed rotation
 100 to 600Rpm (16:1)
Dedicated to
reciprocating (F+R)
mode. Adjustment from
10° to 360° in forward
and in reverse motion by
step of 5°
Parameters selection
Reciprocating movement
Whatever the file used, the angle should be higher in cutting direction than in non cutting edges direction.
Ex : Wave One (150° REV – 30° FWD), Protaper (150°FWD – 30° REV)
Major Advantages
Fractures
• Cyclic fatigue
 File is deformed due to tension and compression motion
performed in curved canals
 Can be reduced:
- Following the file manufacturer settings (speed)
• Torsion
 File’s tip is blocked in the canal but the contra-angle continues
its rotation.
 Can be reduced:
- Using system for limiting the torque
- Following the suggested settings of the manufacturer
Reciprocating movement
Whatever the file used, the angle should be higher in cutting direction than in non cutting edges direction.
Ex : Wave One (150° REV – 30° FWD), Protaper (150°FWD – 30° REV)
Major Advantages
Files - Reciprocating
2 files brands dedicated to reciprocating
motions are today existing:
- Wave one® from Dentsply Maillefer
- Reciproc® from VDW:
more aggressive but also more fragile
Wave one /Reciproc®:
 Reverse helix
 Fixed angulations:
150° REV - 30° FWD
Single use
Files - Reciprocating

Standard protocol:
1. K10 file: Canal exploration
2. WaveOne until penetration length of the manual file
(back-and-forth motion, debris removal on the file, irrigation)
1. Manual file to pre-enlarge until the apical third
2. WaveOne until the working length + irrigation

Files prices
• Rotating files:
– Hero Shaper Micro-Mega  26,42€ without tax for 3 files (8,80€/file)
– ProTaper  39€ without tax for 6 files 6,5€/file
According to studies, a file life cycle in continuous rotating motion varies
between 4 to 10 uses (depending on the shape of the canal treated).
• Reciprocating files:
– WaveOne  38,98€ without tax for 3 single use files
 WaveOne (Small, primary, large) Reciproc R25, 40, 50 (length 21, 25, 31)
 Files dedicated to the reciprocating motion (reverse helix)
 Fixed angulations: 150° - 30°
Price analysis:
Max 10€ without tax/file – Uses: max x10 - min x4 = [1€-2,5€]
WaveOne 13€ without tax/file
WaveOne/Reciproc files are 5 to 13 times more expensive than traditional rotating files
