Dental pulp necrosis

This study tested whether adding photodynamic therapy (a light-activated treatment) to standard sodium hypochlorite irrigation better kills bacteria in root canals. 64 adults needing root canal treatment were randomly assigned to receive either sodium hypochlorite alone or with p…

This study compared three approaches for treating dead, infected adult teeth: a regenerative procedure that induces bleeding inside the tooth, standard cleaning and sealing, and a combination. Fifty-four adults with an infected upper premolar were treated and followed for healing…

This study tested a new, less invasive way to treat infected baby molars in children aged 4 to 10. Instead of fully cleaning out the tooth canals (standard pulpectomy), the new method uses an antibiotic paste to kill infection without drilling. The study involved 110 children and…

This study tested two types of ceramic dental restorations for teeth that have had root canal treatment: overlays and endocrowns. Twenty-five patients received one of the two restorations, and researchers checked how well they fit, any color changes at the edges, and how satisfie…

This study tested a new way to treat children aged 6 to 18 who have a dead nerve in an immature tooth. The new method uses a material called MTA to help the tooth form a hard barrier, compared to the standard treatment with calcium hydroxide. The goal was to see which method work…

This study looked at using a special filling material called OrthoMTA for root canals in second baby molars that have no permanent tooth growing underneath. Thirteen children received the treatment and were checked for up to 12 months to see if the tooth stayed healthy and infect…

This small pilot study tested a new way to treat dead (necrotic) teeth in 6 adults. Doctors took pulp tissue from a healthy donor tooth, mixed it with a growth factor concentrate (CGF), and transplanted it into the dead tooth. After 12 months, they checked if the tooth regained f…

This study tested three different materials (blood clot, platelet-rich fibrin, and concentrated growth factor) combined with two types of rinses to help regrow root tissue in 30 immature permanent teeth with dead nerves. Participants aged 9 to 25 were followed for 12 months using…

This study tested whether transplanting pulp tissue from a healthy tooth into a dead one could restore vitality. Twenty-one adults with dead single-rooted teeth received either a pulp transplant, a pulp transplant with growth factors, or standard root canal treatment. The goal wa…

This study tested how well cold, heat, and electric pulp tests detect tooth nerve health in 175 adults needing root canals. Researchers compared test results to direct observation of nerve bleeding during treatment. The goal was to find which test is most accurate for diagnosing …

This trial compares two irrigation solutions used during regenerative endodontic treatment for immature permanent teeth with infection. Forty children aged 9 to 16 will receive either octenidine or EDTA as a rinse, and their pain levels will be tracked for a week. The goal is to …

This study tested whether using special lasers during root canal treatment can lower pain afterward compared to standard methods. Forty-five adults with infected front teeth were split into three groups: one got standard cleaning, another got a combination of two lasers, and the …

This study looked at 120 people who needed root canal treatment on their molars. Researchers tested different filling materials (bioceramic vs. resin-based) and techniques (cold vs. warm filling) to see which caused the least pain afterward. The goal is to help dentists choose op…

This small study tested two methods for cleaning infected root canals: ultrasonic activation and a 980-nm diode laser. Sixteen adults with dead (necrotic) teeth had their root canals cleaned with one of these methods. Researchers checked for leftover bacterial DNA to see which me…

This completed study measured two immune proteins, IL-8 and IL-10, in fluid from the gums and around the tooth root during root canal treatment. Researchers wanted to see how these levels change as treatment progresses in people with infected, dead tooth pulp. Twenty-two adults a…
