Which onlay lasts longest? new study pits three materials Head-to-Head

NCT ID NCT07157410

First seen Jun 26, 2026 ยท Last updated Jun 26, 2026

Summary

This study compares three different tooth-colored onlay materials used to repair back teeth with deep cavities that extend below the gum line. Each of the 18 adult participants will receive three onlays made from different materials. Researchers will check the onlays at 2 weeks, 6 months, 18 months, and 24 months to see how well they hold up, whether they cause sensitivity, and if new decay develops. The goal is to identify which material performs best for this type of dental restoration.

What this could lead to
If successful, this could help dentists choose the most durable and safe onlay material for repairing deep cavities in back teeth.
What could go wrong
This is a small, early-stage study with only 18 participants, so results may not apply to everyone. Some onlays may chip, loosen, or cause sensitivity.
