Summary
Brief summary
A randomised controlled trial will be conducted on patients undergoing endodontic treatment in the Royal Dental Hospital of Melbourne. Two medicaments, placed inside the root canals of teeth, will be compared: Calcipulpe (calcium hydroxide paste) and Odontocide (calcium hydroxide and ibuprofen paste). Following treatment, patients will be required to record pain scores on a Visual Analogue Scale corresponding to specified times prior to and following treatment. If the amount of pain following treatment is severe enough, requiring the patient to take oral analgesics (rescue analgesia), then details regarding further drug administration will be recorded by the patient.
