We all know that a number of patients can become very nervous about visiting their dentist, and children in particular often require that extra level of support, consideration and understanding.

Whilst few people are scared of basic checkups and cleaning, it’s when something out of the ordinary is required, such as having an injection prior to either an extraction or other work that things can become tense.

Injections can instil fear in a great many people, and the very idea of having a needle anywhere near their mouth and gums is enough to put people off having treatment done, even when it is necessary. Children tend to flinch and move about, and of course this can make having an injection even worse.

Add on to that the fact that traditional injections can cause bleeding and soreness, and it is clear that a new alternative to anaesthetic injections seems like good news all round. Injex is a new type of anaesthetic delivery system, doing away with the need for traditional needle based anaesthetics.

Anaesthetic Injections, Without The Needle - A Review Of Injex

Introducing Injex – A New Option For Dentists

Injex is a new anaesthetic delivery system which does not require the use of a needle or a traditional injection. You might remember in the old Star Trek episodes the doctors would not use needles, but would instead press something against the skin, then there would be a short sound like a brief burst of gas escaping, and that would be it.

No needles, no pain, and nothing to get worked up or worried about. It was quick, easy, and of course entirely fictional.

Until now. Because this is pretty much exactly how the new Injex delivery system works. By simply pressing the Injex delivery system against the gums it is possible to deliver a local anaesthetic submucously down the periosteum. The immediate advantage of this is of course the fact that patients can be reassured that no needle is involved, and therefore no sharp pain. But there are several other benefits from this method of delivery.

The Many Benefits Of The New Injex System

For example, because the anaesthetic is delivered through the gingiva or lower gum of the tooth it is diffused much more rapidly, which means that it takes effect a good deal sooner. Often the anaesthetic gets to work within just a few seconds, with no waiting around for it to get to work. Not only does this save time, but less waiting around helps patients to remain calmer.

Another benefit is the fact that because of the difference in the way the anaesthetic is delivered, the actual dose can be significantly lower than when using a needle. This is ideal when treating children, since they often require a much lower dose limit

Additionally the anaesthetic delivered through the Injex system actually lasts a little longer than when it is delivered through a needle, which means that there is little or no need for additional injections throughout the treatment.

It is important however that when using the needle free Injex system patients are advised that there will be a short sharp sound when it is delivered. Although there is no pain associated with this, the sudden loud sound can cause people to flinch if they are not expecting it.

Although there is rarely any bleeding, it is sometimes possible that the Injex system will cause very minor damage to some of the smaller capillaries, but this bleeding will almost always stop well before the end of the treatment.

With less numbness after the treatment is over, it really does seem as though this is an exciting alternative to using needles, and something which we are likely to see many patients specifically looking out for when choosing their dentist.

    The etiology, or cause, of plaque-induced gingivitis is bacterial plaque, which acts to initiate the body’s host response. This, in turn, can lead to destruction of the gingival tissues, which may progress to destruction of the periodontal attachment apparatus.”:;”
