Intrapulpal injection: factors related to effectiveness
1Division of Endodontics, University of Colorado School of Dentistry, Denver, USA.
Unlabelled:
The intrapulpal injection is commonly used when conventional anesthetic techniques fail during endodontic procedures.
Objectives:
This was a double-blind clinical study conducted to determine whether anesthetic solution was related to an effective intrapulpal injection.
Study Design:
Thirty-five intrapulpal injections were given, all with back-pressure and either saline solution or anesthetic (2% lidocaine with 1:100,000 epinephrine).
Results:
Thirty-three of the 35 injections were effective. Statistical analysis showed no significant difference between the two solutions.
Conclusions:
Data indicate that an effective intrapulpal injection depends on back-pressure and is independent of the solution used.
