To investigate the effect of supplemental lingual infiltration (LI) mandibular molars following an inferior alveolar nerve block (IANB) plus buccal (BI) in patients with irreversible pulpitis.Eighty adult diagnosed pulpitis participated this prospective study. All received standard IANB via injection 4 mL 2% lidocaine 1 : 100,000 epinephrine. Ten minutes after IANB, numbness lower lip were randomly divided into two groups. In BI group, 40 0.9 4% articaine (BLI) epinephrine and, subsequently, LIs same anaesthetic solution and dose. Endodontic access cavity preparation began 15 min IANB. Pain during treatment was recorded using a Heft-Parker visual analogue scale. Success defined when pain 'none' or 'mild' on endodontic initial instrumentation. The estimated statistically analysed by chi-squared test (α = 0.05).The success rates for BLI groups 70% 62.5%, respectively. No statistical difference found between (P 0.478).Supplemental are not recommended administration pulpitis, because they do improve BI.
