Comparing two ways to restore root-canaled back teeth
Part of Mouth & dental clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have two back teeth (molars) that have had root canal treatment and need a crown or filling.
- The tooth structure around the gum line must be healthy enough for the dentist to place the restoration.
- You must have healthy or well-controlled gums (no active gum disease).
- These back teeth must be in functional use (they are used for chewing).
- You can be a smoker or non-smoker.

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 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 ceramic materials for making crowns on back teeth that have had root canals. It aims to see which material works better for long-lasting dental restorations.
This study tests different ways to restore back teeth (molars) that have had root canal treatment using custom-fitted caps called overlays. The goal is to find which design works best to protect these teeth long-term.
This study tests three different methods (digital, conventional, and biomimetic) to restore a back tooth that had a root canal and needs a crown-like covering. It aims to find which approach works best over one year.
This trial tests whether a newer “bulk-fill” way of placing tooth filling works as well as the usual step-by-step method for restoring back teeth with cavities. It aims to see which approach best meets dental quality standards over one year.
