*Always administer an initial .05cc injection to provide subtopical anesthesia for painless application.

When making an infiltration injection with the SyriJet, a small increment of anesthetic is being used. It is therefore necessary to inject into an area where the anesthetic will be retained. If the solution is injected into the mucobuccal fold as with a needle injection, it will tend to spread laterally, with very little of the solution reaching the nerve plexus, and operative anesthesia will not be obtained.

SyriJet injection should be directed to a point approximately 1/3 from apex toward gingival crest. (See first two figures on left)

Procedure: Cavity Preparation

Volume Set At: .10 - .15cc

(After initial .05cc injection)

Lift lip and dry the tissue.

Place the tip of the SyriJet as high as possible on the attached tissue, GENTLY in contact and at RIGHT ANGLES to the surface of the tissue.

Do Not compress the tissue; Do Not exert pressure.

Drop the lip.

Hold the instrument motionless and gently "squeeze" the trigger.

Do not lift the lip immediately after injection.

Extractions: Permanent Upper Anteriors and All Primary Teeth

THESE PROCEDURES REQUIRE TWO (2) INJECTIONS. (After initial .05cc injection)

First injection - Apex infiltration (same as above)

Volume .10 - .15cc

Second injection is a lingual injection. ( See third figure on the left)

SyriJet tip is placed approximately 1-3 millimeters above the gingival margin.

Volume .05cc
