概括

一项为期12个月的研究发现,单色通用和多色纳米混合树脂复合材料显示了可接受的光学性能,并且在后部修复中没有边际变色. 虽然多色彩复合材料在9-12个月后具有更好的颜色匹配,但两者都符合临床成功标准.

科学领域:

牙科材料科学牙科材料科学
恢复性牙科恢复性牙科
临床牙科临床牙科

背景情况:

单色通用树脂复合材料提供了简化的色调匹配.
评估长期光学特性和边际完整性对于修复材料至关重要.

研究的目的:

为了在12个月内比较单色通用树脂复合物的光学行为和边际变色,与多色纳米混合树脂复合物的光学行为和边际变色.
评估这些材料在后期修复中的临床性能.

主要方法:

一项为期12个月的分口,双盲随机研究,涉及20名患有后病变的患者.
修复使用单色通用 (Omnichroma) 或多色纳米混合 (Tetric®N-Ceram) 树脂复合材料进行.
颜色匹配和边缘变色在基线和1,3,6,9和12个月时使用修改后的USPHS标准进行视觉评估.

主要成果:

在6个月后,在两组之间没有观察到颜色匹配和稳定性的统计学上显著差异.
在9个月和12个月后,多色调组显示了统计学上显著的更高的颜色匹配 (阿尔法分数) 流行率.
在12个月期间,两组的所有修复都没有出现边际变色 (阿尔法分数).

结论:

单色通用和多色纳米混合树脂复合材料都表现出令人满意的光学性能和12个月后后部修复的边缘变色.
通过阿尔法和布拉沃分数来定义的临床成功,得到了两种材料类型.
虽然多色彩复合材料在以后的时间点在颜色匹配方面提供了轻微的优势,但单色彩复合材料提供了可行的替代品.

Changes in Skin Color: Clinical Perspectives

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Blinding

Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
