What is an important factor in the manipulation of alginate impressions?

An important factor in the manipulation of alginate impressions is reviewing the shelf life before use. Alginate is a material that has a specific shelf life due to its composition and the potential for degradation over time. If alginate is used past its shelf life, it may not set properly, leading to inaccuracies in the impression. Using fresh material ensures that it has the right properties for optimal performance, such as proper viscosity and setting time, which are crucial for obtaining accurate dental impressions. It is essential to check expiration dates and storage conditions to ensure the best outcome for dental procedures. This attention to detail helps prevent the risk of complications or compromised results in patient care.
