Article Abstract

This study aims to evaluate the adsorptive, adhesive, and wetting energetic properties of five commercially available cleansers in contact with model dental polymer (PMMA). It was assumed that the selected parameters allow for determining the optimal concentration and place of key component accumulation for antibacterial activity in the bulk liquid phase and prevention of oral plaque formation at the prosthetic material surface. The adsorptive (Gibbs' excesses , critical micellar concentration) and thermal (entropy and enthalpy) surface characteristics originated from surface tension and dependences. The surface wetting properties were quantified upon the contact angle hysteresis formalism on the advancing , receding contact angles, and as the input data, which yield a set of wettability parameters: 2D adsorptive film pressure, surface free energy with its dispersive and polar components, work of adhesion, and adhesional tension, considered as interfacial interaction indicators. In particular, molecular partitioning and are indicators of the efficiency of particular active substance accumulation in the volume phase, while , /, and point to the degree of its accumulation at the immersed polymer surface. Finally, the liquid penetration coefficient and the Marangoni temperature gradient-driven liquid flow speed were estimated.
