Enhancing Anaesthetic Success in Mandibular Molars With Symptomatic Irreversible Pulpitis: A Comparative Randomized Controlled Trial

Ain Shams University188 enrolled

Overview

The goal of this clinical trial is to assess the effect of * Preoperative intraligamentary corticosteroids injection * Cryotherapy which is cold application on : * Hard tooth structure ( crown of the tooth ) * Soft tissue overlying roots on the efficacy of the inferior alveolar nerve block anaesthesia in patients with mandibular molars with symptomatic irreversible pulpitis. The main question it aims to answer are: • Does intraligamentary dexamethazone injection increase the success rate of inferior alveolar nerve block without the need for oral premedication. Participants will describe their preoperative pain level to the investigator and describe their pain level during the treatment. Researchers will compare cryotherapy to see if it increases the success rate of inferior alveolar nerve block.

Conditions

Interventions

Patients receive 0.8ml of dexamethazone by periodontal ligament injection 30 minutes before the inferior alveolar nerve block

1,1,1,2 tetrafluoroethaneOTHER

EndoIce (1,1,1,2 tetrafluoroethane) applied on the buccal, lingual (3 s/surface), and occlusal surfaces (4 s) for a total of 10 s then standard IANB was administered

intraoral soft tissue cryotherapyOTHER

Small ice packs (wrapped in sterile gauze) placed intraorally in the mouth on the vestibular surface of the treated tooth for 5 minutes then standard IANB was administered
