Objective

We compared the anesthetic efficacy of inferior alveolar nerve block (IANB) plus buccal infiltration (BI) and IANB plus periodontal ligament (PDL) articaine injections in patients with irreversible pulpitis in the mandibular first molar.

Study design

Fifty-seven volunteers, patients with irreversible pulpitis in the mandibular first molar admitted to the Department of Stomatology, Second Affiliated Hospital, Sun Yat-Sen University, randomly received conventional IANB, containing 1.7 mL 4 % articaine/HCl with 1:100,000 epinephrine, plus either BI or PDL injections containing 0.4 mL articaine/HCl with 1:100,000 epinephrine. The patients recorded the pain of the injections and endodontic access on a Heft–Parker visual analog scale (VAS).

Results

According to the VAS scores, all patients experienced no or mild pain with BI and PDL injections after the application of IANB. Anesthetic success occurred in 81.48 % for IANB plus BI (IANB/BI) compared with 83.33 % for IANB plus PDL injection (IANB/PDL injection). None of the observed differences between the 2 groups was significant (P > .05).

Conclusion

Both injection combinations resulted in high anesthetic success in patients with irreversible pulpitis in the mandibular first molar.
