AbstractPurposeTo evaluate and compare the efficacy of 2% lidocaine containing adrenaline with and without hyaluronidase in inferior alveolar nerve blocks for patients requiring bilateral mandibular extractions.Patients and MethodsThis was the split‐mouth study conducted on 26 patients requiring bilateral mandibular teeth extraction. All the patients were assigned randomly to one of the two groups: (i) 2% lignocaine HCl + 1:2,00,000 adrenaline + hyaluronidase (75 IU) solution will be administered on one side which is the experimental side and (ii) 2% lignocaine HCl + 1:2,00,000 adrenaline solution on the other side is control side. In the first session, the patients randomly received the inferior alveolar nerve block with or without hyaluronidase in one side of the oral cavity. One week later, the same patient received the other technique which was not received in the first session. We also evaluated the onset, duration and need of any supplementary anaesthesia in both the groups.ResultsComparison of VAS score in the control group (2.73 ± 0.724) and experimental group (3 ± 0.693) showed statistically insignificant results (p = 0.177). Whereas the onset of local anaesthesia showed a statistically significant difference between the two groups (p < 0.001) mean of control group (2.73 ± 0.47) and experimental group (1.15 ± 0.23). Comparison of duration of anaesthesia showed a statistically significant difference (p < 0.001) with the mean duration of the experimental group being higher (106 ± 7.94) than the control group (86.27 ± 3.90). Comparison for the need for supplementary anaesthesia showed no statistically significant difference between the two groups.ConclusionWe conclude that if hyaluronidase is used, better blocks with smaller volumes are produced. LAs with hyaluronidase have been shown to improve the quality and effectiveness of anaesthetic blocks and shorten the time it takes for anaesthesia to begin, accelerate the onset of akinesia and lessen the need for additional anaesthesia. It also increases the duration of anaesthesia.
