[Effect of pH on the surface roughness of heat cured denture base acrylic resins].

Unlabelled: Atomic force microscopy can be used to observe the surface changes of dental acrylic resins, providing valid information about the degradation and performance in time of these materials.

Aim: To investigate the influence of pH on the surface roughness of heat cured denture base acrylic resins using atomic force microscopy.

Material And Method: Two commercially available heat cured denture base acrylic resins were used to fabricate 18 test samples (2,5x1 cm2).
