Root canal tools and fillings for lower premolar pain
Part of Pain clinical trials.
This study compares different root canal instruments and filling materials to see which cause less pain after the procedure. If you have a painful or sensitive lower premolar, this could help find a gentler treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a lower premolar (a back tooth with two cusps) that is either pain-free but still has a nerve that responds slowly, or has an inflamed nerve causing pain.
- The tooth must be mature (fully grown) and the gums around it must be healthy.
- You must not have any serious health conditions like diabetes, be pregnant, or have a weakened immune system.
- You must not have taken antibiotics in the last month or painkillers in the last week.
- The tooth should not have an infection at the root tip, be dead, or have other complications like blocked canals or internal root damage.

This study compares how much pain you experience after root canal treatment depending on which type of sealing material is used. Root canal treatment removes infected tissue from inside a tooth; this trial helps dentists find the approach that causes the least post-treatment discomfort.
This study compares how much pain people feel after a single root canal treatment on a lower back molar. It may help find a way to reduce discomfort after the procedure.
This study compares two ways of doing root canal treatment to see which causes less pain right after the procedure. If you have a painful but not infected tooth, this could help your dentist reduce your discomfort during and after treatment.
This study compares two types of root canal filling materials—a resin-based sealer and a bioceramic sealer—to see which one causes less pain after the procedure. If you have a tooth with a painful, infected nerve (irreversible pulpitis), this trial may help determine which filler offers better comfort.
This study compares pain after two ways of doing a root canal on lower back teeth with an inflamed nerve (irreversible pulpitis). It may show which method causes less pain after treatment.
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.
