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

Not Applicable

• Conditions: Anesthesia; Reaction; Pain
• Interventions: Procedure: Type of block injection

• Registration Number: NCT01329874
• Lead Sponsor: Mashhad University of Medical Sciences

Brief 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.

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.

Arm && Interventions

Group	Intervention	Description
Gow gates ,conventional block injection	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.

Primary Outcome Measures

Name	Time	Method
Number of participant who will have pain following Gow gates or traditional inferior alveolar nerve block	6 months	All participant asked to show their pain degree on VAS for evaluation the efficacy of two different block injections and two different infiltrations ( Buccal and lingual) as supplementary injections.

Secondary Outcome Measures

Name	Time	Method
Heart rate monitoring	before and after block injections (day 1)	These records will be monitored by pulse oximeter device
