Summary
Wetting properties of visible light-cured denture lining materials were evaluated. These materials showed similar wettability to conventional denture materials, impacting comfort and retention.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
Background:
- Denture lining materials' wettability influences salivary lubrication, crucial for denture retention and patient comfort.
- Understanding wettability is key to improving denture performance and user experience.
Purpose of the Study:
- To investigate the wettability of ten commercially available visible light-cured denture lining materials.
- To compare the wetting characteristics of visible light-cured materials with conventional denture materials.
Main Methods:
- Evaluated wettability of ten soft and hard visible light-curing materials, one autopolymerized hard lining material, and one autopolymerized denture base material.
- Measured equilibrium and hysteresis contact angles using the dynamic contact angle analysis (Wilhelmy technique).
Main Results:
- Equilibrium contact angles ranged from 59.9 to 77.3 degrees.
- Contact angle hysteresis ranged from 14.7 to 30.6 degrees.
Conclusions:
- Visible light-cured denture lining materials demonstrate wetting properties comparable to conventional hard lining and denture base materials.
- These findings suggest comparable salivary lubricating effects and potential for similar denture retention and comfort.
