背景情况:

目前的牙结合协议依赖于化水性树脂.
优化整洁单体的透动力学到干切牙是改善粘附的关键.
甲基二硫氧化物 (DMSO) 可以修改牙表面特性,以增强树脂透.

研究的目的:

调查是否二甲基硫氧化物 (DMSO) 预处理可以复制化水性树脂在粘合于干蚀牙上的有效性.
为了评估纯甲基酸盐基单体的透动态到DMSO预处理的牙.
用这种修改方法评估使用这种修改方法创建的树脂-丁键的长期耐用性.

主要方法:

人类牙被H3PO4蚀刻并空气干燥.
样品经过50%乙醇DMSO的预处理,持续20或60秒.
用三步蚀刻和冲洗粘合剂或无溶剂的富含水树脂进行粘合.
经过24小时和2年的储存,测试了微拉力键强度.
使用SEM分析了纳米泄漏和混合层完整性.

主要成果:

DMSO预处理显著影响了对蚀刻干牙的粘合 (p=0.001).
长期老化降低了结合强度,特别是在某些树脂组成和DMSO应用时间 (p=0.007) 的情况下.
清洁的富含疏水性树脂直接与DMSO处理的牙结合,其长期性能与"黄金标准"湿结合 (p>0.05) 的长期性能相当.

结论:

通过使用DMSO干结合来降低牙的水化状态,便于直接合整洁的甲基酸盐基树脂.
这种方法显示出开发新策略的潜力,以提高树脂-牙接口的耐用性.
这些发现表明,对于改善寿命的传统湿结合协议来说,这是一个可行的替代方案.

Adhesion

Adhesion

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow...

Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
