Effect of Needle Design on Pain from Anesthetic Injections
Abstract
The purpose of this randomized double blind clinical study was to evaluate theeffectiveness of a large bore compared to a standard bore dental hypodermic needle inreducing pain when applied during inferior alveolar (IA) and long buccal (LB) nerveblock injections. Twenty active duty military or DoD beneficiaries undergoing routinedental treatment were anesthetized using a split-mouth design with four anestheticdental injections. One side of the mouth received an IA and LB injection using the 27-gauge large bore Septoject XL syringe needle. The other side received IA and LBinjections using a 27-gauge standard bore Septoject needles. Each patient then ratedthe pain experienced with each method using a 100 mm Visual Analogue Scale (VAS).Results: The mean VAS score and standard deviation for the IA injection was 38.9 22.7 mm for the large bore needles and 37.1 22.4 mm for the standard bore needles.For the LB injection, the mean VAS score and standard deviation was 33.5 22.8 mmfor the large bore needles and 35.1 19.6 mm for standard bore needles.
