Comparing warm and conventional lignocaine for dental anesthesia

Comparative Evaluation of Anesthetic Efficacy of Warm and Conventional 2% Lignocaine for the Success of Inferior Alveolar Nerve Block (IANB) in Mandibular Permanent Molars: A Randomized Controlled Clinical Trial

Phase 2 Interventional Armed Forces Institute of Dentistry, Pakistan · NCT06806202

This study tests if using warm lignocaine instead of room temperature lignocaine makes dental anesthesia more effective for patients getting root canal treatment on their lower back teeth.

What this trial studies

This study evaluates the effectiveness of warm versus conventional 2% lignocaine for inferior alveolar nerve block in patients undergoing root canal treatment for mandibular molars. A total of 200 eligible patients will be randomly assigned to receive either room temperature or pre-warmed lignocaine, with the aim of assessing success rates and onset times of anesthesia. The study will be conducted at the Armed Forces Institute of Dentistry, ensuring informed consent and ethical oversight throughout the process.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18-50 with carious mandibular molars and acutely inflamed pulp.

Not a fit: Patients with non-vital teeth, those on preoperative medications, or individuals who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve pain management during dental procedures, leading to better patient experiences and outcomes.

How similar studies have performed: While the specific approach of using pre-warmed lignocaine is less common, similar studies have indicated that temperature can influence anesthetic efficacy, suggesting potential for success.
