Patients gave a verbal pain score, from 0-10 for each injection. Results: One Hundred participants were included in study, 37 (37%) males and 63 (63%) females. Mean pain score for group A for the inferior alveolar nerve block was 4.50 ± 2.1 and group B was 3.86 ± 2. The mean pain score for the buccal nerve block in group A was 4.02 ± 1.7, while that of group B was 3.94 ± 1.8.
