I have heard a great deal about the Vibraject which attaches to the barrel of the syringe and creates small vibrations which makes injections almost painless. The vibrations confuse the nervous system so it does not know what to feel. This can be used for blocks, infiltrations and PDL injections. Is it worth the investment? Does this really make injections almost painless?
According to the company:
Vibraject’s “effectiveness is based on the Gate Control Theory of nerve function proposed in 1965 by psychologists Ronald Melzack and Patrick Wall. In short, the theory suggests that nerve endings sense vibrations first and then cannot transmit feelings of pain. So the vibrations essentially mask your patients’ discomfort, putting them at ease during even the most dreaded injections.”
“The VibraJect’s ability to assist in the reduction of pain perceived by the patient was assessed by qualified dentists in a randomized controlled clinical trial at Queen’s University Belfast, N. Ireland. The study involved 329 patients and it was found that by using the VibraJect, patient’s perception of pain was reduced. This was statistically highly significant, indicating less painful injections for patients, especially in the most painful areas, whereas in this particular study, topical anesthetic did not. The involved dentists gave positive feedback such as its ease of use, efficiency, and its non-invasiveness. Overall, it was deemed to be a useful tool in the quest to improve dentist-patient rapport. ”
