This study tests whether taking vitamin D3 before a root canal can reduce pain afterward. Fifty-four adults with low vitamin D and painful tooth inflammation will receive either a single high dose, a three-day course, or a placebo. Pain levels and painkiller use will be tracked f…

This study compares two treatments for severe tooth pain: vital pulp therapy, which tries to save the tooth's nerve, and standard root canal treatment, which removes it. Researchers will measure pain after 24 hours and one week, and check healing at 6 and 12 months using AI to re…

This study looks at two ways to clean root canals (rotary vs. reciprocating files) and whether rinsing with very cold saline (cryotherapy) reduces pain after the procedure. Sixty adults with infected but painless teeth will be randomly assigned to one of four groups. Patients wil…

This study looks at whether rinsing with a green tea extract (EGCG) during a tooth-saving procedure (pulpotomy) can lower pain and improve success rates in adults with severe tooth decay. 64 participants with deep cavities will receive one of two rinses and one of two filling mat…

This study tests two ways to clean a tooth during a root canal: laser-activated irrigation and passive ultrasonic irrigation. Researchers want to see which method leads to less pain and better quality of life afterward. 90 adults with infected or damaged permanent teeth are takin…

This study looks at pain after root canal treatment in adults with a tooth condition called irreversible pulpitis. Researchers are testing three different sealers (materials used to fill the root canal) to see which one leads to the least pain and need for painkillers. 75 partici…

This study looks at whether applying cold therapy (cryotherapy) during a pulpotomy—a procedure to save a decayed tooth—can lower pain and improve quality of life afterward. About 82 adults with severe tooth pain will be treated, and their pain levels and daily comfort will be tra…

This study tests whether adding tiny antibacterial particles called mesoporous silica nanoparticles to standard root canal medication can reduce pain and kill more bacteria. Forty-two adults with infected lower molar teeth will receive one of three treatments: standard medication…

This study looks at different ways to clean a tooth during a root canal to see which causes the least pain and improves quality of life. 90 adults with a specific type of tooth infection will be randomly assigned to one of three irrigation methods. They will report their pain lev…

This study tests whether a single injection of dexamethasone (a steroid) near the tooth can reduce pain after root canal treatment for people with severe, irreversible tooth inflammation. 44 adults with this condition will receive either the steroid or a placebo (salt water) inje…

This study tests two medications—Chlorhexidine gel and Nitrofurantoin paste—placed inside the tooth during root canal treatment to see which one reduces pain between visits better. 220 patients with infected teeth will report their pain levels before treatment and again after 24 …
