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.

Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
