概括

大量填充树脂基复合材料 (RBCs) 的高强度,短时间的光固化可能是热安全的,但证据有限. 避免使用这种方法在深空洞中,以防止热损伤.

科学领域:

牙科牙科是指牙科的专业.
材料科学材料科学材料科学
生物医学工程生物医学工程

背景情况:

大量填充树脂基复合材料 (RBC) 广泛用于牙科修复.
标准的光固化协议可能会耗时.
高强度,短时间的光固化提供了一个潜在的节省时间的替代方案.

研究的目的:

与标准协议相比,在使用高强度,短时间光固化时评估散装RBC的温度升高.
综合现有的体外证据,以分析大量填充红细胞的不同光固化策略的热效应.

主要方法:

在体外研究的系统审查和元分析.
在主要的科学数据库 (PubMed/MEDLINE,Embase,Web of Science,Scopus,虚拟健康图书馆) 进行的搜索,截至2025年4月.
进行了两个元分析,比较了各种增量厚度 (1-4mm) 的3s/10s和3s/20s光固化协议.

主要成果:

包括6项研究,其中大多数具有偏见的高风险.
一项元分析显示,3s对10s固的温度增加具有统计学意义 (p=0.008).
另一项元分析发现,3s对20s治愈没有显著差异 (p=0.20).
证据的整体确定性被评为非常低.

结论:

大量填充红细胞的高强度,短时间的光固化似乎是基于有限的体外数据的热适用.
这种证据的确定性非常低.
由于潜在的热损伤风险,应避免在含有薄残留牙的深腔中进行临床使用.

Accelerated Curing of Concrete

Accelerated Curing of Concrete

Accelerating concrete curing is achieved by applying heat and additional moisture. This process accelerates the hydration of the cement, resulting in an earlier strength gain in the concrete. Steam curing is a method wherein the concrete products are either transported through a chamber on a conveyor belt or encased in plastic, allowing steam at atmospheric pressure to circulate freely around them. This process begins with a phase of moist curing that typically lasts between 3 to 5 hours, after...
