SYNOPSISThe purpose of this study were to examine the effect of 4-META/MMA-TBB resin containing calcium chloride dihydrate (CaCl
2) on dentin remineralization and its mechanical properties. Different percentages of CaCl
2(5%, 10%, and 30%) were added to 4-META/MMA-TBB resin. The Ca
2+ released from CaCl
2 bound to the phosphoprotein formed hydroxyapatite crystals to initiate dentin remineralization in 5%, 10% and 30% CaCl
2 groups in vitro dentin mineralization system. Mineral induction time decreased with increasing of CaCl
2 concentration in the resin. Vickers hardness and bending strength of 5% CaCl
2 group were significantly higher than other groups. The results of elasticity analysis for the control, 5% and 10% CaCl
2 groups showed no significant difference, and the viscosity analysis showed no significant difference between 4-META/MMA-TBB resin with up to 10% CaCl
2 and the control.
The 4-META/MMA-TBB resin with 5% CaCl
2 showed dentin remineralization activity with good mechanical properties.
Key words: 4-META/MMA-TBB resin, CaCl2, dentin remineralization, mechanical properties, bio-active material
