Comparing different types of resin fillings for root‑canal‑treated molars
Part of Mouth & dental clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your tooth must have had a root canal.
- The cavity must be above the gum line, on the top of the tooth and only one side.
- The top part of the tooth must have a defect that covers more than one‑third of the distance from the groove to the tip, and at least one cusp is involved.
- The tooth must have an opposing tooth or a fixed bridge or crown to bite against.
- The tooth must have neighboring teeth (no gaps on either side).
- You must not grind your teeth, have a jaw joint disorder, or be allergic to dental resin materials.

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 trial tests a special printed material used for tooth overlays (caps that cover the entire top of a back tooth). If you need a full overlay on a molar that has had root canal treatment, this study may be a good fit.
This study compares two ways to rebuild a molar tooth that has had a root canal: one uses a 3D printer (additive), the other uses traditional milling (subtractive). The goal is to see which method lasts longer and works better over 2 years.
This trial tests two types of dental cement (a bioactive kind and a conventional self-adhesive kind) for placing crowns or large fillings on back molars that have had root canals. The goal is to see which cement works better to keep the restoration secure and the tooth healthy.
This study compares two types of tooth-filling materials for small cavities on chewing surfaces of molars. Researchers want to see which material lasts longer and works better in your mouth.
This study compares two ways to restore back teeth that have had root canal treatment: using a custom-made ceramic onlay (indirect method) or a tooth-colored composite filling (direct method). It aims to see which approach lasts longer and looks better.
