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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Gow gates ,conventional block injection | No Intervention | 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. |

| Number of participant who will have pain following Gow gates or traditional inferior alveolar nerve block | 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. | 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Heart rate monitoring | These records will be monitored by pulse oximeter device | before and after block injections (day 1) |
