To evaluate the effect of buffered lidocaine with self reporting of pain elicited during maxillary labial and palatal infiltrations of permanent canines.
A standardized, prospective clinical trial of adult volunteers using a cross-over design of 20 paired injections using conventional 2% lidocaine with 1:100,000 epinephrine as the control.
Failed to establish a significant reduction in pain scores for either injection site when buffered lidocaine was injected intraorally.
评估在上颌恒尖牙唇侧和腭侧浸润麻醉期间使用缓冲利多卡因并让患者自我报告疼痛所产生的效果。
一项针对成年志愿者的标准化前瞻性临床试验，采用交叉设计，使用常规的2%利多卡因加1:100,000肾上腺素作为对照进行20对注射。
当口腔内注射缓冲利多卡因时，未能证实两个注射部位的疼痛评分有显著降低。
