Dental overlay showdown: which cavity design lasts longer?
NCT ID NCT07614451
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at two different ways to prepare a tooth for a dental overlay after a root canal. Fifty adults with treated molars will get either a traditional retentive design or a newer, less invasive non-retentive design. Over two years, dentists will check how well each restoration fits, wears, and holds up. The goal is to see which approach works better for everyday dental care.

- What this could lead to
- If successful, this could help dentists choose the best cavity design for durable, long-lasting overlays on root-canal-treated molars.
