2. PDLA Advantages and Indications
Immediate onset – no latency time
Profound single tooth anesthesia
Simple extractions
Cavity preparations
Endodontic treatments
Scaling etc.
Overcomes failed conventional techniques – efficient supplement to inefficient blocks and infiltrations
Teeth in more than one quadrant can be treated at the same sitting.

3. PDLA Advantages and Indications
Gentle pain control due to a very small injection dose
No soft tissue numbness
Replaces most palatal injections
Reduces substantially the risk of haematoma
Contra-indications
Acute infections
Deep periodontal pockets

4. PDLA with PAROJECT®
The needle is introduced into the gingival sulcus along the mesial or distal tooth surface until the alveolar bone crest is contacted (2-3 mm into the periodontal space).
To avoid trauma of the root surface, the needle should be introduced with the bevel facing the root.

5. PDLA with PAROJECT®
With the needle in the injection site, rotate the needle a few degrees to allow an unobstructed flow into the spongious bone.
Inject slowly (5-10 sec. per click).
Visible sign of efficiency = blanching of gingiva around the injection site.

6. PDLA with PAROJECT®
If necessary to reach distal locations, the needle can be bent by using the sterile inside of the needle cap.

7. Why PAROJECT®? Features and Benefits
Safety
Permits slow and controlled injection.
Injects only 0.06 ml per “click” permitting non-traumatic injection.
Risk of cartridge breakage virtually eliminated. However, the barrel is designed to protect the patient if it should happen.
Ergonomics
Compact and user friendly design.
Good “feel” / tactile control during injection.

8. Why PAROJECT®? Features and Benefits
Durability
Made from high-grade acid resistant stainless steel and heat resistant polymer.
Withstands sterilization by any method (max. 200ºC / 390ºF).
No chromium plating to come loose.
Simplicity
Easy to load, unload and clean.
Takes standard dental cartridges and needles.
Non intimidating pen-style design.

9. To load PAROJECT®
Disassemble the syringe into two parts – barrel and lever housing.
Remove the plunger by pulling it through the lever housing.
Screw on a disposable dental needle.
30G X-short Septoject needle with bevel indicator.

10. To load PAROJECT® Insert a standard cartridge into the barrel.
Screw the barrel onto the the lever housing.
Push the plunger through the lever housing until contact is made with cartridge.
NOTE: The plunger can only be inserted by the rear end of the lever housing, and with the smallest smooth part first.

11. Maintenance of the PAROJECT®
Can be sterilized by any method up to 200º C/392 F.
Like all stainless steel instruments, the syringe should be cleaned and carefully rinsed before sterilization (Anaesthetic solutions are highly acidic).
When attention is paid to the above, PAROJECT® will function and appear as new for many years.
