Two root canal tooth repair methods compared
Part of Mouth & dental clinical trials.
This trial tests two ways to fix teeth that have had root canals: one method uses a custom-made ceramic or zirconia onlay placed by the dentist, and the other uses a tooth-colored filling material shaped directly in your mouth. The goal is to find which method works better for restoring strength and appearance.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need to have two root canal-treated back teeth (molars) that need restoration, allowing the dentist to test two different methods.
- Your gums must be healthy, and any gum disease should be under control.
- The affected teeth should have enough natural tooth structure above the gum line to support the new filling or crown.
- The teeth must be in a position where they meet the opposite teeth for biting and chewing.
- Both smokers and non-smokers can participate.

This study compares two types of tooth-colored ceramic crowns for back teeth that have had root canal treatment. The goal is to see which material works better and lasts longer, helping you keep your natural tooth strong.
This study compares two ways to restore teeth that have had root canals, focusing on back teeth. It aims to see which approach is more conservative and effective, which may help preserve more of your natural tooth and improve long-term outcomes.
This study compares two ways to restore (cap) back teeth that have had root-canal treatment and lost a cusp or more. Researchers want to see which method—computer-milled or 3D-printed crowns—works better and lasts longer.
This study compares two types of resin onlays (custom‑made fillings) to see which works better for molars that have had a root canal. If you have a back tooth with a root canal and a cavity on the top and one side, this trial may help decide the best repair.
This study compares two types of dental cement used to attach ceramic crowns to back teeth that have had root canal treatment. The goal is to see which cement works better and lasts longer.
This study compares two ways of preparing a back tooth (molar) for an overlay filling after a root canal. It aims to find which method works best for restoring strength and function to the tooth. If you need an overlay on a treated molar, this trial could help improve your dental care.
