Abstract
This study investigated the usefulness of a dental laboratory polymerization unit with light-emitting diode (LED) as a light source. The depth of cure (n=15), water absorption and solubility (n=9) of two indirect composite materials (Cesead N and Solidex Hardura) were evaluated by five dental laboratory polymerization units (LED Cure Master, Twinkle LED, α-Light V, α-Light II, and Hyper LII). Statistical analysis was performed by one-way ANOVA and Tukey test or non-parametric tests. Comparison of light sources for curing depth showed that metal halide had the highest value, followed by the LED group with similar values, and halogen lamps with the lowest value. The water absorption and solubility of the composite specimens polymerized with the three LED laboratory polymerization units were within the ISO recommended limit.
本研究调查了以发光二极管（LED）为光源的牙科实验室聚合装置的实用性。五种牙科技工室聚合装置（LED Cure Master、Twinkle LED、α-Light V、α-Light II 和 Hyper LII）对两种间接复合材料（Cesead N 和 Solidex Hardura）的固化深度（n=15）、吸水性和可溶性（n=9）进行了评估。统计分析采用单因素方差分析和 Tukey 检验或非参数检验。对光源的固化深度进行比较后发现，金属卤化物灯的固化深度值最高，其次是 LED 灯组，数值相近，而卤素灯的固化深度值最低。使用三种 LED 实验室聚合装置聚合的复合试样的吸水性和溶解性均在国际标准化组织建议的限度之内。
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
