title: Wettability of visible light-curing denture lining materials.
abstract: OBJECTIVE
  Wetting characteristics of denture lining materials indicate the degree of salivary lubricating effect, which promotes denture retention and patient comfort. This in vitro study investigated the wettability of ten commercially available visible light-cured denture lining materials.
  
  
  METHODS
  Ten soft and hard visible light-curing materials, one autopolymerized hard lining material, and one autopolymerized denture base material were evaluated for wettability. Wettability was estimated by measuring the equilibrium and hysteresis contact angles using the dynamic contact angle analysis, or Wilhelmy, technique.
  
  
  RESULTS
  The equilibrium contact angle ranged from 59.9 to 77.3 degrees, and contact angle hysteresis ranged from 14.7 to 30.6 degrees.
  
  
  CONCLUSIONS
  Visible light-curing lining materials exhibit wetting properties similar to the conventional hard lining and denture base materials.
