Effect of prolonged brushing with different agents on surface characteristics of conventional and 3D-printed denture resins.

ABSTRACT: Given the increasing use of three-dimensional (3D) technology, evaluating the effects of prolonged brushing on denture base resins is necessary. This study evaluated the influence of long-term brushing with cleaning/disinfection agents on the surface properties of heat-cured and 3D-printed denture base resins. Resin discs were produced and randomly divided into groups: T0: no brushing; T1: simulated 1-year brushing; T2: simulated 2-year brushing. A soft-bristled toothbrush was used with one of the solutions: dentifrice (Colgate TOTAL®), disinfectant soap (Lifebuoy®), or distilled water (negative control group). Color stability, roughness and hardness (n = 9 each) tests were performed. Surface topography was analyzed by Scanning Electron Microscopy (n = 2). Data were analyzed using the Mann
