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.
