摘要: In order to investigate the clinical application of paint-on resins, effect water absorption on toothbrush abrasion and light transmittance ten crown resins including three was examined. Water into each material ranged from 0.29 0.89 mg/cm2 after storage in distilled-water for 6 weeks their hardnesses decreased by 3.5-22.3%. Maximum surface roughness (Rmax) materials stored distilled increased with an increasing number cycles 1.9 10.5 microm 100,000 cycles. Also, depth weight loss as indicator amount lost showed similar behaviors Rmax. These results indicated that resistance located middle among all
