In this study, we employed a nonthermal atmospheric pressure plasma (NTAPP) jet to evaluate the effect of plasma treatment on the durability of resin–dentin bonding under a thermocycling challenge. Furthermore, we assessed the degradation resistance of plasma-treated collagen under a sodium hypochlorite (NaClO) challenge. We assessed the beneficial effect of NTAPP treatment on the acid-etched dentin–bonding interface by testing the micro-tensile bond strength and examining the morphology. We found that the immediate bonding strength of the dentin significantly increased after NTAPP treatment. Compared with the control group, NTAPP resulted in a more prominent effect on the bonding durability of the dentin–adhesive interface after treatment for 5 or 10 s. Simultaneously, the mechanical strength of dentin collagen under the NaClO challenge was improved. Our results indicate that, in optimal conditions, NTAPP could be a promising method to protect dentin collagen and to improve the...

非热大气压等离子体通过蚀刻和冲洗系统改善牙本质-粘合剂界面耐久性的体外研究

在这项研究中，我们采用了非热常压等离子体（NTAPP）射流来评估等离子体处理对热循环挑战下树脂-牙本质键的持久性的影响。此外，我们评估了在次氯酸钠（NaClO）刺激下血浆处理的胶原蛋白的抗降解性。我们通过测试微拉伸粘合强度并检查形态，评估了NTAPP处理对酸蚀牙本质-粘合界面的有益作用。我们发现，NTAPP处理后，牙本质的即时粘合强度显着提高。与对照组相比，NTAPP治疗5或10 s后对牙本质-胶粘剂界面的粘合耐久性产生更显着的影响。同时，NaClO刺激下牙本质胶原的机械强度得到了提高。我们的结果表明，在最佳条件下，NTAPP可能是保护牙本质胶原蛋白并改善牙本质胶原蛋白的一种有前途的方法。
