Abstract
The purpose of this study was to evaluate, with theAnalytic Technology electric pulp tester, clinical analgesia in normal, asymptomatic, and symptomatic human vital teeth. Group A consisted of 34 teeth that were classified as normal. Group B consisted of 33 asymptomatic teeth that had restorations, caries, or crown fracture. Group C consisted of 30 teeth with the clinical diagnosis of irreversible pulpitis. Two cartridges (3.6 ml) of 2% lidocaine with 1:100,000 epinephrine were administered by block and/or infiltration. The teeth were tested at various time intervals to determine if they responded to the maximum output (80/80) from the electric pulp tester. If the teeth responded, periodontal ligament injections were given until no response was recorded with the pulp tester. Clinical analgesia was then tested by performing endodontic procedures. The normal and asymptomatic groups had analgesia 100% of the time. In the teeth with irreversible pulpitis, 73% had clinical analgesia.
