Dentistry FAQs

What if more than one shot with INJEX is necessary?

If more than one shot is necessary, there should be 2 prefilled ampoules available. The reset of the injector is a simple process. Dental nurses can do this very quickly. Many dentists invest in 2 or 3 injectors, to save time. 2 - 3 injectors prepared with prefilled ampoules are optimal for every treatment.


Edema at the injection site?

Is the word "edema" the correct characterisation? A swelling can be seen in very few cases, when the injection site is producing an allergic reaction on the preservatives of the local anaesthetic agent.


The Injectors trigger is not working properly, too jerky

The Injectors trigger has a "press point". This point has to be found and it’s position has to be trained. If you start pressing the trigger from this point, you will get a proper injection. The injector will not start producing uncontrolled movements, because the trigger will not perform two different movements.


How should the patient be positioned for injecting with INJEX?

The patient should be sitting upright in a relaxed position. The time between positioning and releasing the injector should be kept as brief as possible with children and especially restless patients.


How should the patient be prepared for injecting with INJEX?

The patient should be informed about the release noise of the injector to prevent defensive arm movement or startle reflexes


Are haematoma possible?

Haematoma at the injection site are still possible even when using a needle-free system.

They might occur with patients taking anticoagulants to treat cardiovascular disease (e.g., Marcumar) or thrombocytic aggregation inhibitors (e.g., ASS100 = time-released aspirin), or patients occasionally taking aspirin for pain relief.

Small bruises can also be due to too little or too much pressure when positioning the injector on the gingiva.


Are oedema at the injection site possible?

Swelling is observed in a few cases, which might also be caused by the local anaesthetic itself (preservatives).


Is bleeding possible?

Bleeding usually does not occur. As with needle injections, INJEX might cause some damage to the uppermost capillaries. In rare cases, this might cause a pin-sized drop of blood to emerge at the injection site. This is especially the case if the patient has been taking medication to treat cardiovascular disease (e.g., Marcumar, ASS100 = time-released aspirin) or normal aspirin for pain relief.


How much anaesthetic should be injected?

The recommended basic dosage is 0.3 ml per injection. A second injection to prolong the effect can be administered at any time. The local anaesthetic dose is still lower than with a conventional syringe in spite of the second injection.


Why is a dose of at least 0.3 ml recommended?

Less than 0.3 ml for the initial injection is not sufficient and the degree of anaesthesia is too low, just as with conventional infiltration anaesthesia.


How quickly does the local anaesthetic become effective after the injection?

The local anaesthetic becomes effective more quickly than after a conventional injection. The injected area is anaesthetized after just a few seconds


How large is the therapeutic window compared with conventional infiltration anaesthesia?

Injecting with INJEX provides a therapeutic window larger than with conventional infiltration anaesthesia due to the better distribution within the tissue.


Is it necessary to check the depth of the anaesthesia?

It is recommended to use a probe to check the anaesthesia depth before commencing treatment. An additional injection may be administered if necessary.


What amounts of anaesthesia may be administered per application?

Each ampoule of the INJEX system may be filled with max 0.3 ml of anaesthetic. A dose of 0.3 ml is recommended for dental applications.


Is the transporter adapter only for single-use?

The transporter adapter is a sterile disposable product and can be used only with one cylinder cartridge to prevent contamination as well as diminishing functionality. Dispose of the adapter when the medication cartridge is empty. The local anaesthetic may crystallize within the adapter if the same adapter is used with additional medication cartridges. This can impair the transfer to the INJEX ampoule.


What happens if I change the injection angle?

A modified injection angle results in an enlarged medication injection point. This may lead to increased bleeding and risk of haematoma.


Can injuries occur to the skin?

Tests with different types of needle-free systems have shown hat the medication chooses the path of least resistance, thus going around blood vessels and nerve fibres to penetrate the subcutaneous adipose tissue.


Is the injection with INJEX painless?

When applied correctly the injection with INJEX is virtually painless. The sensation can be described as a short slight pressure on the skin surface. As pain is felt individually one cannot state a general and obliging assertion. As fluid is pressed under the skin the patient will sense the injection with INJEX more or less, depending on the volume and the individual sensibility. Patients generally assesse the sting from a needle as more unpleasant than the injection with INJEX.

(literature review: DENNE et al., 1992, TEINTZ et al., 1991, RESMAN et al., 1985)

The micro orifice of the ampoule has a diameter of 0.18 mm. Currently, the thinnest needle has a comparatively thick diameter of 0.25 mm.


Can the ampoules be used again?

No. In order to guarantee sterility and function, the ampoules are intended to be used once only.


Is it possible to treat INJEX system components in an autoclave?

No, the utilized materials are not suitable for autoclave treatment. Adapter, ampoules, and SiliTop are sterile products for single-use only. The injector, the reset box, and the transporter are designed for multiple-use and need not be sterilized since they are not in direct contact with the patient.
