【摘要】:目的:觀察生物交聯劑京尼平預處理對牙本質-樹脂粘結面即刻和老化后粘結強度的影響。方法:分別以蒸餾水、無水乙醇、無水丙酮液作為溶劑配置含京尼平濃度為0.05、0.10、0.15 mg/mL的預處理劑,并以純溶劑作為空白對照,分別對酸蝕后的牙本質粘結面進行預處理;然后用Z350納米復合樹脂制備牙本質-樹脂粘結試件,用萬能測試機檢測各組牙本質-樹脂粘結面的即刻和冷熱循環(huán)老化處理后的微拉伸粘結強度。結果:牙本質粘結面經不同溶劑配置的不同濃度京尼平預處理劑處理后,其牙本質-樹脂粘結面的即刻微拉伸粘結強度(除0.05 mg/mL組外),均顯著高于相應的溶劑對照組(P0.05),并且呈濃度依賴性增加;經冷熱循環(huán)老化后,仍以0.1 mg/mL和0.15 mg/mL濃度的京尼平預處理組的微拉伸粘結強度顯著高于相應的溶劑對照組(P0.05),各組老化后的微拉伸粘結強度均明顯低于其未經老化處理的相應組(P0.05)。結論:京尼平預處理可有效保護牙本質-樹脂粘結界面,并能減緩其老化過程。
[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.
