Comparative Evaluation Between the Effectiveness of Vibration Assisted Syringe and Conventional Syringe

Comparative Evaluation Between the Effectiveness of Vibration Assisted Syringe and Conventional Syringe in Decreasing Children Pain and Anxiety Perception During Local Anesthetic Injection ) Randomized Controlled Clinical Trial (

The study will be conducted to evaluate the effect of the vibration assisted syringe on pain perception and anxiety in children during intra oral injection of local anesthesia in comparison with conventional syringe.

As for granted the main concern in pediatric dentistry is to guarantee a positive response from child for any further appointments, that's why we aim to manage a successful dental procedure keeping a stress free situation. Conventional local anesthetic technique is the most commonly used technique for anesthetizing teeth but in turn it has shown the highest levels of discomfort in comparison with other techniques. VibraJect is vibration associated syringe device, it is simple and cost effective solution to alleviate injection discomfort. It works because the light pressure of a Vibraject injection is carried rapidly to the brain by thicker insulated nerve tissues. In contrast, the needle prick travels on thinner nerve tissues, arriving too late for the brain to register the sensation. Vibraject is good news for the patient, because the anesthetic itself causes virtually no discomfort and good news for the dentist, who can work easily knowing that patient, is comfortable.

Group I (study group); children receiving intraoral injection of local anasethia using the vibration assisted syringe.

Group II (control group): children receiving intraoral injection of local anasethia using the standard syringe.

VibraJect; is a small battery-operated attachment that snaps on to the standard dental syringe. It delivers a high-frequency vibration to the needle which is strong enough for the patient to feel.
