What is electronic anesthesia?

Gate Control Theory Of Pain
Transcutaneous Electrical Nerve Stimulation.
www.indiandentalacademy.com
With the proposal of the Gate-Control Theory by Melzack and Wall in 1965, a rational basis for electroanalgesia was elucidated.
dull, slow, diffuse,burning pain is carried from the periphery by small unmyelinated fibres,
while the sensation of light touch is carriedby large myelinated fibers.
Sensations of touch, vibration,and heat could block the pain signals.

TENS signals create impulses that reach pain centers before the body's pain signals do, closing the "gate" to the transmission of pain - like a busy signal on a telephone.

Electronic anesthesia: is delivered via two small sponges attached to a battery-operated control box. The sponges are placed in the patient’s mouth or on the patient’s face. The patient uses the controls on the box to choose and maintain the depth of the anesthesia delivered.

Mechanism of action?
Acts by elevating levels of l-trytophan;serotonin;
b-endomorphins and enkephalins.
All these are analgesicswww.indiandentalacademy.com

ON PEDIATRIC PATIENTS
Objective:- The purpose of this study was to determine the effectiveness and acceptance of electronic dental anesthesia in comparison with local anesthesia in restorative procedures in children.
Results:-Although the success rate of electronic dental anesthesia was less than that of local anesthesia, there was no significant difference between the two methods. On the other hand, 53.6% of the patients preferred electronic dental anesthesia, whereas 35.7% preferred local anesthesia.
Conclusions:- In restorative dental care in children, electronic dental anesthesia appears to be beneficial in reducing discomfort, as judged from behavioral observations and self-reports.

ON ADULTS
A total of 12 patients used the device to see how its ability as an anesthetic compared to that of an injection.
Eleven of the 12 patients found the procedure acceptable.
"One patient did not like having to control the level of current and would have preferred to rely on the dentist," she said.
"The main reason people would choose this method is that they are needle phobic," Ms Fleck said.

ELECTRONIC AND LOCAL ANESTHESIA:-A CLINICAL COMPARISON FOR OPERATIVE PROCEDURESThirty patients, who required restorations on
similar teeth bilaterally, and 10 clinicians were involved in the study. The two teeth in each patient were randomly restored under either electronic or local anesthesia.
Minor after effects in some patients included redness of skin and briefly lingering sensation.
All patients found electronic anesthesia easy to use, and most of the patients (93.3%) thought that the system was good to excellent.

We may not have the ultimate machine or wave form today, and we certainly can expect to see electrode
systems improve in the future. A pain model is needed that simulates the pain of operative procedures to more easily evaluate different electrodes, electrode placements, waveforms, frequencies, and combinations with other pain control modalities.
However, the equipment that exists is a viable, preferred alternative to local anesthesia in
many operative and periodontal procedures. When it fails,
electronic anesthesia still allows one to administer local anesthesia without pain.www.indiandentalacademy.com
