Clinical Trial Summary

The purpose of this study is to determine whether Gow Gates block injection is more effective than conventional alveolar nerve block in anesthetising mandibular molars with acute pulpitis.

Description:

Pain management and adequate anesthesia are of critical importance for the endodontist. Traditionally, mandibular teeth are anesthetized via inferior alveolar nerve block (IAN). However, this technique provides a marginal success rate of 19-56% in patients with irreversible pulpitis.Gow Gates technique introduced in 1973 for anesthetizing of mandibular molars with more accuracy, success and safety.

Intervention

Procedure:
• Type of block injection
Patients will be selected from a group with acute irreversible pulpitis in mandibular molars. Half of the patients randomly selected for receiving gow gates block injection and half will receive traditional inferior block injection by 3.6 ml Lidocaine plus epinephrine.Teeth with no response to anesthetizing will be randomly divided into two group of either buccal or lingual infiltration.
