Comparison of the degree of pulpal anesthesia achieved with the intraosseous injection and infiltration injection using 2% lidocaine with 1:100,000 epinephrine.

This prospective, randomized study compared the degree of pulpal anesthesia obtained from an intraosseous injection to an infiltration injection that used 2% lidocaine with 1:100,000 epinephrine. The success rate for the intraosseous injection was 98%; for the infiltration injection, the success rate was 85%. There was no significant difference between the two techniques. The mean time for the onset of pulpal anesthesia was significantly faster with the intraosseous injection and the infiltration injection resulted in a significantly longer duration of pulpal anesthesia.
