Dental pulp necrosis

This study compares two treatments for infected baby molars in children aged 5 to 8. One group gets a standard antibiotic paste, the other gets simvastatin (a common cholesterol drug). Both are placed inside the tooth after cleaning, and the tooth is sealed. Researchers will chec…

This study tests whether two forms of demineralized dentin matrix (a material made from tooth tissue) can help regenerate immature permanent teeth in children aged 9 to 15. The trial compares these materials to a standard sealing material called RetroMTA. Over 12 months, research…

This study compares two irrigation systems, GentleWave and EdgePro, for cleaning infected root canals in teeth with dead nerves. Researchers will measure how much bacteria is reduced after treatment. 30 adults with permanent teeth needing root canal treatment will participate.

This study tests whether placing ibuprofen, nitrofurantoin, or calcium hydroxide inside a tooth after root canal treatment can lower pain. About 111 adults with dead nerves in their back teeth will rate their pain on a 0-10 scale. The goal is to find which medication works best t…

This study compares two common root canal filling techniques—cold lateral condensation and warm vertical obturation—to see which causes less pain afterward. About 80 adults with infected but pain-free teeth will be randomly assigned to one method. Researchers will measure pain le…

This study tests whether using a special laser along with standard ultrasonic cleaning can reduce pain and kill more bacteria after a root canal. About 120 adults with infected single-root teeth will be treated and asked to rate their pain. The goal is to find a better way to man…

This study surveys 100 French dentists who treat children to understand why they often choose extraction for non-vital baby teeth, even though effective alternatives like pulpectomy exist. The goal is to collect and analyze their treatment choices, reservations, and decision-maki…

This study tests three different devices used during root canal treatment to see which one removes the most bacteria from infected teeth. Ninety adults with dead nerves in their premolars will be randomly assigned to one of the three methods. Researchers will measure bacterial le…
