What this trial studies

This clinical trial investigates how alcohol consumption affects the success of local anesthesia in patients with symptomatic irreversible pulpitis. Seventy adult participants, divided into two groups of alcoholics and non-alcoholics, will receive an inferior alveolar nerve block (IANB) using 2% lidocaine. Pain levels during the procedure will be assessed using the Heft-Parker scale, with a successful injection defined as a pain score below 55. The study aims to provide insights into the relationship between alcohol use and pain management in dental procedures.

Who should consider this trial

Good fit: Ideal candidates include adults with symptomatic irreversible pulpitis in mandibular molars, categorized as either low-moderate alcohol consumers or non-drinkers.

Not a fit: Patients with multiple active dental issues or significant medical contraindications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve pain management strategies for dental patients with varying alcohol consumption habits.

How similar studies have performed: While there is limited research specifically on alcohol's impact on dental anesthesia, studies on alcohol's effects on pain perception suggest this approach could yield valuable insights.
