A SMILE IS THE CHEAPEST ANAESTHESIA THAT MAKES THE PAIN BEAUTIFUL
Pain and dentistry are often synonymous in the minds of patients especially those with significant dental problems.Research has shown that the fear of pain associated with dentistry is closely related with the most common method of blocking pain during dental procedures ie. the administration of local anaesthetics.
This article focuses on the most recent developments in Dental LA techniques and devices.
Local anaesthesia is a technique used to render a part of the body insensitive to pain.
There are no doubt many outdated forms of inducing LA which include mechanical pressure, low temperatures, anoxia, chemical irritants, neurolytic agents like alcohol but the most novel one being the use of chemical agents such as local anaesthetics.
The techniques of administration should also be of prime importance along with the material being injected.
1)COMPUTER-CONTROLLED LOCAL ANESTHETIC DELIVERY SYSTEMS(CCLAD)
This system is one of the first to incorporate the computer technology to the control the rate of flow of anaesthetics. The first of these devices - THE WAND was introduced which enabled the operator to manipulate needle placement with finger tip accuracy and deliver the solution with a foot control.
Accupal is a cordless device that uses vibrations and pressure to precondition the oral mucosa. It's more like a walkie-talkie or a mobile phone. The device begins to vibrate at the site of injection once placed and then the needle is injected.
Syrijet has been on the market for nearly 40 yrs and has gone through some improvements over the years. Most commonly addressed as ANAESTHESIA WITHOUT APPREHENSION , Syrijet is a needle less technique of delivering LA. The needle less approach also includes devices like JET INJECTORS & MED-JET H III which are based on the principle of using mechanical devices that creates enough pressure to deliver the solution through a very small orifice.
It is a small battery operated attachment that snaps on the standard dental syringe. It delivers a high frequency vibration to the needle that is soft enough for the patient to feel the prick.
5)RevVac SAFETY SYRINGE
These syringes operate almost the same as conventional ones. It works on a simple concept; where retracting and pressing the plunger creates a robust vacuum at the time of use.
DEVICES FOR INTRA-OSSEOUS ANAESTHESIA
This product is relatively inexpensive and can be used with equipment already existing in a dental office. The teeth are anaesthetised by injecting the LA solution directly in to the cancellous bone.
This system works by making a pilot drill itself a hollow tube through which a 27 gauge needle can pass. This initial drill stays in place allowing the anaesthetic to be placed at the right position rather than hunting for the hole that was created to pass the needle.
The achievement of good LA requires thorough knowledge of the agents being used, the neuroanatomy involved and the best techniques and devices available. As DENTAL ANAESTHESIOLOGY BECOMES THE 10th DENTAL SPECIALITY researchers and practitioners are walking the road to seek new and better means of delivering the so called SHOT to manage pain.
Even though there is a clear scope with the advancements from CCLAD to the needle less technique which is my personal favourite , the age old plastic syringe is the only available option in most of the dental clinics. Introducing technological change presents a different set of challenges .
Over coming obstacles with a very promising implementation efforts, better communication, innovative promotion and a cost effective approach might let the general public experience the magic of modern machines.
