概括

牙修复颜色不匹配是一个常见的问题. 一年后,Cerasmart显示出比Vita Enamic更好的色彩稳定性,尽管这两种材料在临床接受范围内表现相对较好.

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
审美牙科审美牙科

背景情况:

牙修复颜色不匹配是美学失败和更换的主要原因,特别是在老化后.
在牙科修复中保持长期的颜色稳定性对于患者满意度和临床成功至关重要.

研究的目的:

为了比较Cerasmart混合陶和Vita Enamic聚合物透陶网络 (PICN) 冠冕在临床服务一年后的色彩稳定性.
为了评估两个不同的CAD/CAM材料的美学结果,用于内牙治疗的牙.

主要方法:

102名接受了内治疗的第一牙的参与者接受了Cerasmart或Vita Enamic冠冕.
颜色差异 (ΔE) 用数字光谱仪在基线,6个月和12个月测量.
统计分析包括曼-惠特尼测试,以比较不同组的颜色参数.

主要成果:

在6个月后,与Cerasmart相比,Vita Enamic在亮度 (ΔL*) 和红绿色 (Δa*) 值的变化显著更高.
12个月后,Vita Enamic的修复显示出比Cerasmart更大的颜色变化 (p=0.0120).
尽管在特定时间点存在差异,但在1年的时间内,两种材料的整体色彩稳定性是可比的.

结论:

在临床使用一年后,Cerasmart和Vita Enamic都表现出可以接受的色彩稳定性.
在12个月后,与Vita Enamic相比,Cerasmart表现出更好的色彩稳定性.
这些发现表明,Cerasmart可能为牙修复提供更好的长期美学维护.

Clinical Trials: Overview

Clinical Trials: Overview

Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Clinical Trials

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...
