Summary

This laboratory study examines how three common denture disinfectants—sodium hypochlorite, chlorhexidine, and effervescent alkaline peroxide tablets—affect the surface roughness, hardness, and dimensional stability of two modern denture base materials: PMMA and PEEK. Researchers will compare these effects against a control group soaked in distilled water. The goal is to identify which cleaning method best preserves the quality and fit of CAD/CAM milled dentures.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: denture disinfectants (sodium hypochlorite, chlorhexidine, effervescent alkaline peroxide tablet)
What this could lead to: If certain disinfectants prove safe for these materials, it could help denture wearers choose cleaning methods that keep their dentures in good shape longer.
What could go wrong: This is a lab study on material samples, not on real dentures in people's mouths. Results may not reflect everyday use or long-term effects.
