To evaluate the efficacy of Clinpro XT in reducing dentin permeability and the stability of this effect after different acid challenges.
Sixty-five roots of extracted human third molars were used. From each tooth, one dentin specimen was prepared and connected to a fluid filtration system to measure the dentin permeability after each of the following steps: sample preparation; treatment with 37% phosphoric acid; application of Clinpro XT; three acid challenges. Specimens were randomly assigned to 5 groups (n = 13) according to the acidic solution applied: Coca-Cola, natural lemon juice, wine vinegar, white wine and Red Bull energy drink. An additional 10 third molars were used to evaluate the degree of occlusion of the dentinal tubules and the surface roughness.
Clinpro XT statistically significantly reduced dentin permeability after just a single application. No statistically significant increase in dentin permeability could be detected after three consecutive challenges. The application of Clinpro XT promotes the occlusion of dentinal tubules and reduces the surface roughness.
The Clinpro XT is effective in reducing dentin permeability. This effect persists even after acid challenges.
评估Clinpro XT在降低牙本质通透性方面的疗效以及在不同酸蚀刺激后这种效果的稳定性。
使用65颗拔除的人类第三磨牙牙根。从每颗牙齿制备一个牙本质标本，并连接到流体过滤系统，以在以下每个步骤后测量牙本质通透性：样本制备；用37%磷酸处理；应用Clinpro XT；三次酸蚀刺激。根据所应用的酸性溶液，将标本随机分为5组（n = 13）：可口可乐、天然柠檬汁、白醋、白葡萄酒和红牛能量饮料。另外使用10颗第三磨牙评估牙本质小管的封闭程度和表面粗糙度。
仅单次应用Clinpro XT后，牙本质通透性在统计学上显著降低。连续三次刺激后，未检测到牙本质通透性有统计学意义的增加。Clinpro XT的应用促进了牙本质小管的封闭并降低了表面粗糙度。
Clinpro XT在降低牙本质通透性方面有效。即使在酸蚀刺激后，这种效果仍然持续。
