Abstract
The study was aimed to investigate the effect of grinding status of dentin on all-in-one adhesive/dentin bonding. Human flat dentin surface ground with SiC paper (#180, 600 or 2000) was treated with 2 all-in-one adhesive systems (i Bond or G-Bond). Microtensile bond strength was measured after 24 hour. Additionally, etching effects on the gourd dentin surface were observed in SEM.
