京尼平預(yù)處理對牙本質(zhì)-樹脂粘結(jié)面即刻和老化后粘結(jié)強度的影響
[Abstract]:Aim: to observe the effect of genipin pretreatment on the bonding strength of dentin-resin adhesive surface immediately and after aging. Methods: distilled water, anhydrous ethanol and anhydrous acetone solution were used as solvent to prepare the pretreatment agent containing 0. 05% 0. 1010 mg/mL of geniapine, and pure solvent was used as blank control. The dentin bonding surface after acid etching was pretreated respectively. Then the dentin-resin bonding specimens were prepared with Z350 nano-composite resin. The microtensile bond strength of each group of dentin-resin bonding surfaces was measured by universal testing machine. Results: after the dentin bonding surface was treated with different concentrations of genipin pretreatment with different solvents, the bonding strength of the dentin-resin bonding surface was immediately slightly tensile (except for 0.05 mg/mL group). All of them were significantly higher than the corresponding solvent control group (P0.05), and increased in a dose-dependent manner. The microtensile bond strength of the pretreatment group with 0. 1 mg/mL and 0. 15 mg/mL concentration was significantly higher than that of the solvent control group (P0.05). The microtensile bond strength of each group after aging was significantly lower than that of the corresponding group without aging (P0.05). Conclusion: geniapine pretreatment can effectively protect dentin-resin bonding interface and slow down the aging process.
