Summary

This study looked at whether using electronic devices or X-rays to measure root canal length changes how much pain patients feel after root canal treatment. 125 adults with no prior pain or swelling took part, and each had their root canal measured with one of five methods. Patients recorded their pain levels for 48 hours after treatment. The goal was to find which method causes the least discomfort.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients must meet all of the following criteria to be included in the trial: * Aged between 18 and 60 years. * Diagnosed with asymptomatic irreversible pulpitis in a single-rooted tooth and scheduled for primary root canal treatment in that tooth. * In good general health, with no systemic diseases. * No use of any analgesic medications within the last 24 hours prior to the treatment. * Willing to participate in the study and able to give informed consent. Exclusion Criteria: * Patients who do not meet the above inclusion criteria excluded from the study.

Additionally, patients who decline to participate or who cannot provide informed consent excluded.
