Anesthetic Efficacy of Gow-Gates Versus Conventional Inferior Alveolar Nerve Block Techniques

April 5, 2011 updated by: Mashhad University of Medical Sciences

Comparison of the Anesthetic Efficacy in Mandibular Molars With Acute Irreversible Pulpitis With Either Conventional Inferior Alveolar or Gow-gates Nerve Block Techniques Plus Buccal or Lingual Infiltration

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.

Detailed 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Gow gates ,conventional 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.
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.
Other Names:
  • Gow Gates technique
  • Conventional inferior block injection
No Intervention: Buccal infiltration, Lingual infiltration

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
