Kulzer SOPIRA Citoject Instrucciones De Uso página 7

Insert a disposable needle into the nozzle (5) and screw the hub onto
the thread. We recommend the use of SOPIRA Carpule disposable
needles in the sizes of 0.3 x 12 mm or 0.3 x 16 mm with the corre-
spondig short needle point.
Depress the dosing lever until anaesthetic solution emerges from the
needle point. The syringe is ready for use.
3. Handling the SOPIRA Citoject syringe
Each despression of the dosing lever applies 0,06 ml of anaesthetic.
Normally 0,15 ml–0,20 ml of anaesthetic is required for each root, i. e. 3
depressions of the lever.
Multi-rooted teeth need an appropriate dose of anaesthetic.
4. Performing an intraligamental anaesthesia with SOPIRA Citoject
Intraligamental anaesthesia provides effective and immediate anaesthe-
sia of a single tooth.
One depression of the dosing lever should take about 7 seconds, i. e.
for 0.18 ml per root = 3 depressions of the dosing lever = 21 seconds.
The onset of anaesthesia is generally obtained within 30 seconds
following the injection. Hence the treatment can be started at once.
Recommended procedure is as follows:
• In contact with the tooth, the tip of the needle is
inserted 1–2 mm into the periodontal space
approximally along the tooth axis.
• the needle is correctly placed in the periodontal
space if a steady, uninterrupted back-pressure
is noticeable
• This resistance must be maintained, to secure
penetration of the solution to the apex.
• Inject slowly and uniformly.
