Abstract

Abstract: Objective: To compare the efficacy of 1.7 mL and 3.4 mL articaine for an inferior alveolar nerve block (IANB) when treating molars with symptomatic irreversible pulpitis. Methods: Seventy-six teeth were randomly received conventional IANB injection either with 1.7 mL or 3.4 mL of 4% articaine with 1:100000 epinephrine. The patients recorded their pain before and during access cavity preparation as well as during root canal instrumentation using a HeftParker visual analog scale. Data were analyzed by T and chi-square tests. Results: Seventy-two patients were eligible to participate in this study, which showed that 3.4 mL articaine provided a significantly higher success rate (74.4%) of IANBs compared with 1.7 mL of the same anesthetic solution (27.8%) although neither group had 100% successful anesthesia (P<0.001). Conclusion: Increasing the volume of articaine provided a significantly higher success rate of IANBs in mandibular first molar teeth with symptomatic irreversible pulpitis, but it did not result in 100% anesthetic success.
