title: The effects of the vasoconstrictor epinephrine on the duration of pulpal anesthesia using the intraligamentary injection.
abstract: The use of the intraligamentary injection to achieve dental anesthesia is becoming a popular alternative to conventional dental techniques. This study compares the duration of anesthesia achieved by intraligamentary injection using lidocaine, lidocaine with epinephrine 1:50,000, lidocaine with epinephrine 1:100,000, and epinephrine 1:100,000. Using chi 2 and paired t-test analysis, there was no significant difference found in the efficacy of the agents studied in achieving pulpal anesthesia.
