Effect of Common Analgesia on Pulp Sensibility

Single oral dose of 400 mg ibuprofen administered in a blinded capsule. Prior to dosing, baseline pulpal sensibility tests (cold test with Endo-Ice and Electric Pulp Test) and pain rating (VAS) will be recorded on a contralateral healthy tooth and the target tooth with symptomatic irreversible pulpitis. The drug is given orally and tests are repeated 30 minutes after ingestion. Participants are monitored for adverse effects. Participants who cannot take NSAIDs are excluded

A single oral dose of 500 mg paracetamol administered in a blinded capsule. Baseline pulpal sensibility testing (cold test with Endo-Ice and Electric Pulp Test) and pain level assessment using a Visual Analogue Scale (VAS) will be performed on both the tooth with symptomatic irreversible pulpitis and a contralateral healthy tooth prior to administration. The same tests will be repeated 30 minutes after ingestion to evaluate any masking effect on test results.
