APICAL PERIODONTITIS

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 tested two different materials used in root canal treatment for teeth with both root and gum infections. 120 adults received either a mineral-based plug (MTA) or a standard resin sealer. Researchers measured healing and inflammation markers after one year to see which …

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 looked at whether making a larger opening at the tip of the tooth root helps regenerative dental treatment work better for adults with infected mature teeth. 36 people received one of two treatment sizes and were followed for healing and pain. The goal was to see which…

This study looked at whether using a patient's own blood product (L-PRF) can improve bone healing after surgery for a persistent tooth-root infection. Fifteen adults with large infections around the tooth root were treated and followed for 12 months. The goal was to see if adding…

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 looks at whether people with diabetes experience more pain after a second root canal treatment compared to those without diabetes. About 50 adults with a single-rooted tooth needing retreatment will take part. Pain levels and painkiller use will be tracked for a week a…

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 tested whether using different modes on an electronic apex locator (a tool that measures tooth canal length) during root canal retreatment could reduce pain afterward. 144 adults with infected teeth were split into four groups: one used a standard locator, and three us…

This study tested a procedure called full pulpotomy (removing only the infected pulp inside the tooth crown) in 58 adults with severe toothache. It compared success in teeth with and without an infection at the root tip (apical periodontitis), using an AI tool to help detect the …

This study looked at three different root canal sealers to see if any caused less pain or helped teeth heal faster. Seventy-two adults with infected single-rooted teeth received standard root canal treatment with one of the sealers. Pain was checked right after, at 24 hours, and …

This study looked at whether using sonic irrigation or a diode laser during root canal treatment reduces pain afterward. Eighty adults with infected single-rooted teeth were randomly assigned to one of four cleaning methods. Patients reported their pain levels and painkiller use …

This study tested two different materials—surgical glue and ferric sulfate—to control bleeding during root-end surgery in 34 patients with infected tooth roots. Researchers measured how well each agent stopped bleeding, how much pain patients felt afterward, and their quality of …

This study looked at 42 adults with infected single-rooted teeth to see if using sonic or ultrasonic tools to clean the root canal helps the tooth heal better than the standard method. Participants got one of three cleaning techniques during their root canal, and the size of the …

This study looked at 120 adults needing a root canal to see if one sealer (AH Plus or WellRootST) causes less pain afterward. Pain was checked before treatment and at several points up to one month later. The goal is to help dentists choose the better option for patient comfort.

This study tested whether using 3D-guided microsurgery helps bone heal better after a failed root canal compared to standard surgery. It also compared two different filling materials: a newer bioceramic putty and the standard MTA. Twenty-four adults with persistent infections aft…

This study tested whether using a sonic device (EndoActivator) to clean the tooth during a root canal reduces pain afterward. Fifty-eight adults with tooth infections were randomly assigned to get either the sonic cleaning or standard syringe irrigation. Pain was measured before …

This study tested whether a rinse called octenidine reduces pain after root canal treatment better than the standard rinse chlorhexidine. 142 adults with a single-rooted tooth and asymptomatic apical periodontitis received one of the two rinses during their procedure. Pain was re…

This study looked at 120 adults to see if anxiety and depression are linked to a common tooth infection called apical periodontitis. Participants had dental exams and filled out questionnaires about their mental health. The goal was to better understand how emotional well-being a…

This study looked at whether injecting a substance made from a patient's own blood (injectable platelet-rich fibrin, or i-PRF) could help heal teeth with chronic infection at the root. Sixty adults with infected teeth received standard root canal treatment; half also got the i-PR…

This study looked at whether treating a chronic tooth infection (apical periodontitis) can reduce inflammation and improve the health of blood vessel walls. Researchers measured inflammatory markers and blood vessel barrier proteins in 45 healthy adults aged 25-55, both with and …

This study looked at whether using a special laser (Nd:YAG) during root canal treatment could help reduce inflammation and oxidative stress in infected teeth. Researchers measured certain markers in fluid samples from 58 patients. The results showed that the laser did not provide…
