Summary

This trial tests whether taking a single dose of diclofenac potassium before dental treatment can improve the numbing effect of local anesthesia and reduce pain after the procedure. Adults with severe tooth pain from irreversible pulpitis in lower molars will receive either 50mg, 100mg, or a placebo before treatment. The study measures how well the anesthesia works and how much pain is felt six hours later.
