概括

内障碍物 (IOBs) 增强了白化,内牙治疗的牙的骨折性. TheraCal提供了最重要的强化,在漂白过程中改善了牙完整性.

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:

经过内牙治疗的牙可能容易发生骨折.
冠内白是一种常见的方法,用于变色的内牙治疗牙.
孔内障碍物 (IOB) 的使用可能会影响这些牙的机械特性.

研究的目的:

为了评估三种孔内屏障 (IOB) 材料对经过内牙治疗的牙受冠内漂白的骨折性的影响.
为了比较玻璃离子体水泥,TheraCal和Ionoseal作为IOB的增强效果.

主要方法:

60个抽取的上中央切口器接受了内牙治疗.
牙被随机分为四组 (n=15):玻璃离子体水泥,TheraCal,Ionoseal,或没有屏障 (控制).
用35%的过氧化进行了冠状管内漂白,随后使用通用测试机进行了断裂性评估.

主要成果:

与对照组相比,所有测试的孔内屏障材料都显著提高了断裂性.
TheraCal 显示了最大的强化效应,其次是离子和玻璃离子体水泥.
两组之间观察到统计学上显著的差异 (P < 0.05).

结论:

内障碍物增强了经过内牙治疗的牙的骨折抵抗力,这些牙经过了冠内白化.
在那些被测试用于保持牙完整性的材料中,TheraCal是最有效的材料.
这些发现支持TheraCal在白化过程中作为孔内障碍物的临床使用.

Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
