Alginic acid is a polysaccharide widely present in the cellular walls of brown algae. Alginate is widely used as a mold material in dentistry, in the production of prostheses and in the production of positives for small-scale casting. It is also used in the pharmaceutical, cosmetic and food industries for various uses. The purpose of our study is to assess whether the chemical and physical characteristics of water can influence the characteristics and performance of these materials. These impression materials are often marketed as a powder to be mixed with water, but water is not included during the purchase. We have considered different articles, but unfortunately the results that speak of this topic are few and contain little information. We have therefore carried out a review of the present literature on Pubmed and Embase search engine. The same product used by two people with two different waters will have different characteristics. The possibility of knowing these effects could allow for more performing materials and above all for identical and reproducible materials. In conclusions, the results indicate to follow the manufacturer's instructions, and eventually turn to the use of automatic devices.
海藻酸是一种广泛存在于褐藻细胞壁中的多糖。藻酸盐在牙科领域被广泛用作模具材料，用于制作假体以及小规模铸造的阳模。它还在制药、化妆品和食品工业中有多种用途。我们研究的目的是评估水的化学和物理特性是否会影响这些材料的特性和性能。这些印模材料通常作为粉末出售，需与水混合使用，但购买时不包含水。我们查阅了不同的文章，但遗憾的是，关于这个主题的研究结果很少，且信息有限。因此，我们在PubMed和Embase搜索引擎上对现有文献进行了综述。两个人使用两种不同的水来调配同一种产品，其特性会有所不同。了解这些影响的可能性有助于生产出性能更优的材料，尤其是相同且可重复生产的材料。总之，结果表明应遵循制造商的说明，最终可考虑使用自动设备。
