Preoperative Dexamethasone Injection to Improve Local Anesthesia Success in Endodontic Treatment (DILAS)

2026年8月21日 更新者:Ayesha Sarwar、Watim Medical & Dental College

Preoperative Intraligamentary Injection of Dexamethasone Can Improve the Anesthetic Success Rate of 2% Lidocaine During the Endodontic Management of Mandibular Molars With Symptomatic Irreversible Pulpitis

This study aims to determine whether giving a single dose of 4mg dexamethasone before root canal treatment can reduce the amount of pain patients experience during the procedure . Patients diagnosed with symptomatic Irreversible Pulpitis requiring endodontic treatment will be enrolled. Participants will receive either dexamethasone or placebo before treatment , and pain during the procedure will be measured using a Visual Analogue Scale (VAS) .

The findings may help improve pain management strategies during root canal treatment .

研究概览

详细说明

Symptomatic irreversible pulpitis is a common cause of severe dental pain, and achieving adequate pain control during endodontic treatment remains a challenge despite the use of local anesthesia. Inflammatory mediators present in inflamed pulp tissues may reduce the effectiveness of local anesthetics , resulting in persistent intraoperative pain.

Dexamethasone is a corticosteroid with potent anti-inflammatory properties that may reduce inflammatory mediator release and improve pain control . This randomized controlled clinical trial aims to evaluate the effectiveness of preoperative 4mg dose of dexamethasone compared with placebo in reducing intraoperative pain during endodontic treatment of teeth diagnosed with symptomatic irreversible pulpitis.

Eligible participants will be randomly allocated to receive either dexamethasone or placebo before treatment . Standard local anesthesia and endodontic procedures will be performed for all participants .

Intraoperative pain intensity will be assessed using a Visual Analogue Scale. The primary outcome will be the difference in intraoperative pain scores between the two groups.

The results of this study may provide evidence regarding the role of preoperative dexamethasone as an adjunct for improving pain control during endodontic treatment .
