Abstract
Objective: This study aimed to compare the effectiveness of lidocaine with magnesium sulphate in patients undergoing root canal treatment following irreversible pulpitis.
Methods: A total of 86 patients were randomised to receive 1.8 ml of 2% lidocaine replaced with 0.2 ml of 10% magnesium sulphate with 1: 80,000 epinephrine (n=43) as MGS group and 1.8 ml of 2% lidocaine with 1: 80,000 epinephrine (n=43) as LDC group. Preoperative visual analogue scale (VAS) pain scores were record-ed. Patients were instructed to report any perioperative pain felt during the access cavity preparation and when introducing the first patency file (#10 k) in the root canal and perioperative VAS recorded.
Results: The success rate of the inferior alveolar nerve block (IANB) was higher in the MSG group. The mean+-SD of perioperative pain was 0.16+-0.37 in the MSG group and 3.13+-0.77 in the LDC group. The MGS group produced better anaesthetic efficacy with a p-value of 0.01.
Conclusion: Based on the results, adding 10% magnesium sulphate to 2% lidocaine increased the effective-ness of IANB in patients with symptomatic irreversible pulpitis of mandibular molar teeth.
