About this study

This study aims to compare the pain reduction efficacy of Trypsin-Chymotrypsin and Naproxen sodium after root canal treatment in patients with symptomatic irreversible pulpitis. A lot of patients suffer greatly from post endodontic treatment pain and have a fear of dental treatments due to the pain. Patients refuse to go to the dentists and neglect oral hygiene care. That's why it is very important to find an effective drug regimen to reduce this post treatment pain. The null hypothesis is that there will be no difference between the efficacy and mean pain scores of Trypsin-chymotrypsin and Naproxen Sodium for post-endodontic treatment pain. Conducted as a triple-blinded, parallel, randomized controlled trial, 100 patients will be randomly assigned to receive either Trypsin-Chymotrypsin or Naproxen sodium following standard root canal therapy. Pain levels will be assessed using a numerical rating scale at 1, 6, 12, and 24 hours post-treatment to evaluate the effectiveness of these two pain management modalities.
