Which of the following is NOT an advantage of using glass ionomer in premeasured capsules?

Using glass ionomer in premeasured capsules offers several advantages that enhance both the efficiency and effectiveness of dental procedures. One significant benefit is consistency in mixing; premeasured capsules ensure that the exact amount of powder and liquid are combined every time, leading to reliable results. This consistency eliminates variability that can arise from manual mixing techniques, where different practitioners may mix the materials differently, affecting the final product's properties.

Additionally, the convenience of premeasured capsules means there is no need for manual measurement, streamlining the process and saving time. Such convenience can enhance workflow, particularly in a busy clinical setting where efficiency is paramount.

The availability of a wide variety of shades is another advantage, as glass ionomer can be matched to various dental materials and patient needs, allowing for aesthetically pleasing restorations.

In contrast, the statement that results can vary is not an advantage; rather, it indicates inconsistency, which is typically considered a downside. Premeasured capsules are designed to provide uniformity in results, making them a preferred choice for many dental professionals. Thus, the correct choice highlights an aspect that does not align with the typical benefits of using glass ionomer in this form.
