Two independent studies have confirmed the effectiveness of the VibraJect dental needle attachment to block the pain of dental injections.
The first study by Fred Quarnstrom, DDS, et al., dealt with pain level comparisons resulting from usage of the Wand with those compared to usage of the VibraJect dental needle attachment.
The second study by Queens University statistically measured and compared the amount of pain reduction experienced by patients who were given block injections of local anesthesia using the VibraJect dental needle attachment as compared to block injections given to subjects using conventional injection methods.
This conclusion of the study by Dr. Quarnstrom, et al., stated:
"This study tends to indicate there is little difference in the pain perceived by a dental patient when injected using the Vibraject as opposed to injecting with the Wand."
The conclusion of the study from Queens University, Belfast Ireland, concluded: " The vibrating syringe attachment resulted in reduced pain levels on receiving intraoral injections."
