概括

生物-C Temp® (BC) 导致更多的牙变色,并且比UltraCal XS® (UC) 和纯氧化 (CH) 具有较低的抗菌活性. 在这项内药物治疗研究中,BC还显示了较低的pH值,与UC和CH相比.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
牙科材料科学牙科材料科学

背景情况:

内药物对于根管治疗期间的消毒至关重要.
选择正确的内药物平衡了有效性与牙变色等潜在副作用.

研究的目的:

为了比较Bio-C Temp® (BC),UltraCal XS® (UC) 和纯氧化物 (CH) 对牙颜色,pH和抗菌活性的影响.
为了评估这些内面粉的临床适用性.

主要方法:

使用CIEL*a*b*系统测量了颜色变化.
在多个时间点 (3, 24, 72, 168小时) 记录了pH值.
通过阿加扩散和直接暴露试验评估了抗菌活性,并使用ANOVA,Kruskal-Wallis和弗里德曼试验进行统计分析.

主要成果:

与对照组相比,Bio-C Temp® (BC) 的冠状颜色变化明显更大,60天后L*值更高.
在3小时和72小时,BC的pH值低于UC和CH.
在直接暴露测试中,BC显示了减少的抗微生物抑制区,并允许微生物生长,而CH则完全抑制了生长.

结论:

与UltraCal XS® (UC) 和纯氧化 (CH) 相比,Bio-C Temp® (BC) 导致更显著的牙变色,并且具有较低的抗菌疗效.
BC还表现出较低的pH值,可能会对内环境产生不同于UC和CH的影响.

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...
