Cairo, New CairoAges 18–40 - NCT05221450Recruiting
Study of what affects root canal treatment outcomes
This study looks at which factors can change how well root canal (endodontic) treatment works. It may help improve future care by understanding what leads to better healing.
LjubljanaAges 18 years+ - NCT05439330Recruiting
Dental MRI to help diagnose jaw, gum, and tooth problems
This study tests whether a special dental MRI can give useful pictures to diagnose jaw joint problems, tooth-related tissue changes, and gum/inflammation issues, and to help plan some dental implant treatments. If you need imaging for these reasons, the trial may help doctors choose the best next treatment by using clearer, dedicated scans.
AarhusAges 18 years+ - NCT06574152Recruiting
Light therapy for pain relief after dental root surgery
This trial tests whether a special light treatment, called photobiomodulation, can help reduce pain and speed up healing after a specific type of dental surgery on the root of a tooth. The surgery involves a small cut in the gum, and the light may help the gum recover faster.
Houston, TexasAges 18 years+ - NCT07059481Recruiting
Root canal sealers and oxidative stress study
This study is looking at how different types of root canal filling materials (sealers) affect oxidative stress markers in the body. It is for people with a single tooth that has a chronic infection at the root tip and needs a root canal.
Ordu, Ordu- AltınorduAges 18–45 - NCT06587048Recruiting
New bone window surgery for root canal infections
This trial tests a new way to perform root-end surgery using a special ultrasound device. It aims to treat infections at the tip of a tooth root by making a small opening in the bone, which may help you heal faster.
Rohtak, HaryanaAges 18–60 - NCT07388901Recruiting
Comparing two root canal sealers for infection treatment
This trial compares two materials (iRoot SP and nRoot SP) used to fill root canals after infection. It aims to see which works better for healing apical periodontitis, an infection around the tooth root.
Hangzhou, ZhejiangAges 18 years+ - NCT06543004Recruiting
Comparing pain after root canal with two filling materials
This study is comparing two different materials used to fill the tooth after a root canal to see which one causes less pain afterward. If you need a root canal on a front tooth or a premolar and you don't have pain or swelling, this trial may help find the gentler option for you.
DohaAges 18–60 - NCT07256691Recruiting
Bioceramic vs. resin sealer for root canal pain
This study tests two types of sealing materials used in root canals (a newer bioceramic one vs. a standard resin one) to see which causes less pain after treatment. If you have an infected, pain-free tooth that needs a root canal, this trial may help guide better care.
Lahore, Punjab ProvinceAges 18–55 - NCT07198919Enrolling by invitationPhase 1/Phase 2
Pain relief during root canal for infected tooth: gel vs. antibiotic paste
This trial compares two medicines placed inside a tooth after root canal cleaning to see which reduces pain better between appointments. If you have an infected single-root tooth and are between 16-45 years old, you may be able to join.
Karachi, SindhAges 16–45 - NCT07603934RecruitingEarly Phase 1
Testing Medications Inside Root Canals to Reduce Pain
This study tests different medications placed inside a tooth's root canal during treatment to see which one best reduces pain afterward. If you have a tooth with a dead nerve (necrotic pulp), this trial might help determine the best way to manage your pain during the healing process.
Cairo, Cairo GovernorateAges 18–40 - NCT04605445Recruiting
One vs two dentist visits for infected root canals
This study compares whether treating an infected, dead tooth in one visit works as well as using two visits. It may help you and your dentist choose the simplest schedule while still clearing infection and supporting healing.
Vaxjo, Kronoberg CountyAges 18 years+ - NCT06043453Recruiting
Revitalizing injured, growing permanent teeth
This trial tests a new approach to help injured, still-growing permanent teeth heal and continue to develop naturally. It may be an option if your child has a traumatized tooth with an infection and the root is not yet fully formed.
GhentAges 6–18 - NCT06466538RecruitingPhase 2/Phase 3
Boswellia vs standard medicine for root canal infection
This trial tests whether a natural gum resin (Boswellia) placed inside the tooth during root canal treatment can fight infection better than standard medications. It may be a good option for people with a single-rooted tooth infection who are otherwise healthy.
Al MansurahAges 20–60 - NCT06545084Recruiting
Better healing after root-end surgery using a special blood clot
This study tests whether adding a concentrated blood clot (L-PRF) to standard root-end surgery helps tooth-related infections heal faster and better. You may be a good fit if you have a persistent infection at the tip of a tooth root and need this type of surgery.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06566508RecruitingPhase 2/Phase 3
Gotu kola gel for root canal infections
This study tests a natural gel made from asiaticoside (a compound from the Gotu kola plant) placed inside your root canal after cleaning. This gel may help reduce infection and inflammation better than standard medicines.
Al MansurahAges 20–60 - NCT06843525Recruiting
Bite force measurements for molar dental work
This trial measures how your bite force changes after getting a filling or root canal on a lower back tooth. It helps doctors understand if different dental treatments affect your ability to chew.
Newark, New JerseyAges 18–89 - NCT07048028Recruiting
Chitosan rinse for root canals in premolars
This study tests a new natural mouth rinse (chitosan) during root canal treatment for lower premolar teeth. Researchers want to see if it helps clean the tooth better than standard treatment.
Ordu, AltınorduAges 18 years+ - NCT07237620Recruiting
Comparing medicines for failed root canal treatment
This trial compares different medicines placed inside the tooth after a failed root canal to help heal the infection at the root tip. If you have a back tooth that still has an infection even though it had a root canal years ago, this study may test which medicine works best for you.
Hatay, AntakyaAges 18–60 - NCT07297836Recruiting

Amman, Amman GovernateAges 18 years+ - NCT07448571Recruiting
Testing i-PRF for better root canal retreatment healing
This study tests whether using a special platelet-rich concentrate (i-PRF) during a root canal retreatment can help heal infection at the tip of the root better than standard retreatment alone. It is for adults with a previously treated upper front tooth that now shows signs of infection on X-ray.
IstanbulAges 18–50 - NCT07453576Recruiting
Comparing bleach strengths for root canal retreatment pain
