Comparative Assessment of Mental/Incisive and Inferior Alveolar Nerve Block Anesthesia in Root Canal Treatment of Mandibular Premolars

Not Applicable

Completed

• Conditions: Mandibular Nerve; Mandibular Nerve Blocks; Premolars; Mental Nerve Block

• Registration Number: NCT06679660
• Lead Sponsor: Cukurova University

Brief Summary

The goal of this clinical trial is to systematically compare the pain scores and anesthesia efficacy of IANB and MNB in the treatment of symptomatic mandibular first and second premolars. This study aims to address gaps in current evidence and clarify whether these anesthesia techniques differ in effectiveness and patient experience during endodontic procedures. The hypotheses include: (i) no difference in pain perception between IANB and MNB, (ii) no difference between first and second premolars with IANB, and (iii) no difference between first and second premolars with MNB.

Primary Outcome Measures

Name	Time	Method
Numerical Rating Scale	Following anesthesia administration, a 10-minute waiting period was observed. Patients completed a Numerical Rating Scale immediately upon initiation of the endodontic cavity procedure and again after the start of pulp extirpation.	The patients were asked to rate the pain experienced during endodontic access cavity preparation and pulp extirpation using a Numerical Rating Scale. The Numerical Rating Scale was printed on A4 paper, scaled to fit horizontally, with values from 0 to 10 displayed along a bar. The Numerical Rating Scale uses a 0 to 10 scale, with increments of one unit. Patients were instructed to mark '0' if they experienced no pain, select a value between "1" and "3" for mild pain, a value between "4" and "6" for moderate pain, and a value between "7" and "10" for severe pain.
