About this trial
The goal of this randomized clinical trial is to evaluate whether different root canal preparation systems and sealer types affect postoperative pain after root canal treatment in adult patients (18-60 years) with asymptomatic irreversible pulpitis in mandibular premolars.
The main questions it aims to answer are:
Do different instrumentation systems (TruNatomy vs ProTaper Gold) influence postoperative pain levels? Do different sealer types (AH Plus vs TotalFill BC) affect postoperative pain and analgesic consumption? Researchers will compare TruNatomy and ProTaper Gold systems combined with AH Plus or TotalFill BC sealers to determine their effect on postoperative pain.
Participants will:
Undergo single-visit root canal treatment using one of the assigned file system and sealer combinations Record their pain levels using a Numerical Rating Scale (NRS) at specific time intervals (6, 12, 24, 48, 72 hours, and 7 days) Take ibuprofen only if needed and record analgesic intake Attend a follow-up visit on the 7th day
