A root canal procedure involves cleaning the inside of the tooth. Two common cleaning solutions are chlorhexidine (CHX) and sodium hypochlorite (NaOCl, also known as bleach). While both are effective, it is not clear if one causes more discomfort than the other.\n\nIn this research, half of the participants will have their root canal cleaned with CHX, and the other half with NaOCl. We will then ask all participants to rate their pain 24 hours after the procedure using a simple pain scale. Our goal is to see if there is a difference in pain levels between the two groups. The results will help dentists choose the best solution to make their patients more comfortable after treatment",[61],"Postoperative Pain",[63,64],"Postoperative pain","Root canal treatment","NOT_YET_RECRUITING","2026-03-03",{"date":68,"type":69},"2026-03-05","ACTUAL",{"date":71,"type":55},"2026-02-15",{"date":73,"type":55},"2026-06-15",{"name":5,"class":6}]
