APICAL PERIODONTITIS

This study tests whether oleanolic acid, a natural plant compound, works better than standard medicines (calcium hydroxide and Ledermix) when placed inside a root canal. The goal is to reduce bacteria and inflammation in teeth with infection. Thirty-six adults with infected singl…

This study compares two methods to clean infected root canals during a single dental visit: laser-activated irrigation and sonic-activated irrigation. Sixty adults with chronic apical periodontitis (a tooth infection) will receive one of the two treatments. Researchers will measu…

This study compares two materials used to seal the tip of a tooth root during surgery for persistent infections after root canal treatment. About 110 adults will receive either MTA or TotalFill BC-RRM Fast Set Putty. Researchers will check healing with 3D X-rays after one year to…

This study compares two types of dental sealers used during root canal treatment: TotalFill (a bioceramic sealer) and AH Plus. The goal is to see which one leads to better healing of infections at the tooth root tip. 170 teeth from adults at a dental clinic in Singapore are being…

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 tests whether adding N-acetylcysteine (NAC) to standard root canal treatment can reduce pain and improve healing in people with infected, dead teeth. Forty adults with mature teeth and signs of infection around the root tip will receive either NAC or standard medicatio…

This study looks at two different materials used to fill root canals after infection. 64 adults with infected but painless teeth will get one of the two sealers. Researchers will track pain for a week and check healing with X-rays over time to see which works better.

This study tests two different pastes placed inside the tooth between root canal visits to see which one reduces pain and helps the bone heal better. Eighty adults with infected but painless front teeth will receive either Bio-C Temp or Metapaste. Pain is tracked for a week, and …

This study tests whether using ozone water during root canal treatment can reduce oxidative stress (a sign of inflammation) in the jawbone. Sixty adults with a single-rooted tooth and a silent infection will be randomly assigned to receive either ozone water or salt water as a fi…
