Introduction: Malamed (12) recommends positioning patients upright for anesthetic administration believing it will help improve pulpal anesthetic success. The purpose of this study was to compare anesthetic success in healthy subjects with vital, asymptomatic teeth when an inferior alveolar nerve (IAN) block was given in an upright and supine position. Materials and Methods: One hundred-ten healthy subjects were given inferior alveolar nerve blocks (IANB) using 2% lidocaine with 1:100,000 epinephrine while in the upright and supine position, at two different appointments, spaced at least two weeks apart. Subjects used a Heft-Parker VAS to report pain of needle insertion, needle placement, and solution deposition. The molars, premolars, and incisors were tested with an electric pulp tester (EPT) every four minutes for fifty-five minutes post-injection. Pulpal anesthesia was considered successful when two consecutive 80/80 EPT readings were recorded within fifteen minutes of the injection, and the 80/80 readings were sustained for 55 minutes. Results: Injection pain in both upright and supine groups, on average, was reported as mild, except for needle placement, which was reported as moderate. In the upright group, pulpal anesthetic success rates were 65.5% for second molars, 53.6% for first molars, 52.7% for second premolars, 57.3% for first premolars, 22.7% for lateral incisors, and 8.2% for central incisors. In the supine group, success rates were 72.7% in second molars, 59.1% in first molars, 62.7% in second premolars, 75.5% for first premolars, 28.2% for lateral incisors, and 10.9% for central incisors. Pulpal anesthesia was statistically more successful in the supine group (p=0.0009). Conclusions: The supine position was found to be statistically more successful than the upright position. However, the difference may not be big enough to be significant clinically since a large percentage in each group was not numb.
