Cement failure in dental procedures can often be attributed to an increase in solubility, which can cause the cement to dissolve over time when exposed to oral fluids. In scenarios where the cement is meant to provide a strong bond and a seal, increased solubility can lead to the failure of that bond, resulting in loosening of restorations or crowns, or even recurrent caries due to microleakage.

In contrast, excessive thickness can influence the setting behavior and overall strength of the cement, but it is not a direct cause of overall failure in the same way that solubility issues can manifest in oral environments. Improper mixing technique can certainly affect the consistency and performance of the cement, but it is not as universally impactful on the long-term durability of the material. Lastly, incompatibility with enamel can create bonding challenges, but it may not necessarily lead to the breakdown of the cement in the same manner as increased solubility does. Thus, the solubility of the dental cement is a critical parameter in predicting its longevity and efficacy within the moist environment of the mouth.
