The effect of denture cleansers on temporary soft liners.
Circular samples of commonly used liners were prepared and immersed in solutions of nine cleansers. Solutions were changed daily for a period of 1 month. Six properties were tested: color change, porosity, surface distortion, size change, water sorption, and solubility. Statistical analysis was applied to measurements to evaluate performance of both cleansers and liners. The results demonstrate that selection of a liner cannot be based on a single property. Changes in resiliency of the liners were not tested in this experiment, but it is recognized that this could be an important factor in liner selection. The liners found to be least affected by the cleansers were Lynal, Tissuedyne, F.I.T.T., and Hydro-Cast, in that order. Viscogel, Softone, and Veltec were most affected. Clorox/Calgon and Miller demonstrated the same overall average performance, tying for first place for four of the liners. Clorox/Calgon was compatible with most liners (six of eight). Mersene and Duo tied for third and fourth places. The thickness of liner materials made little difference on the effects of the cleansers on the properties evaluated.
