Which feature is essential for ensuring the longevity of dental cement?

The essential feature for ensuring the longevity of dental cement is its resistance to solubility and strength against disintegration. This property plays a critical role in maintaining the integrity of dental restorations over time. Dental cement must be durable and able to withstand various stresses, such as those encountered during chewing and other oral functions. If the cement dissolves or disintegrates over time, the bond between the restoration and the tooth structure can weaken, leading to failure of the restoration.

When evaluating dental cements, it is vital that they demonstrate minimal solubility in the oral environment, which includes contact with saliva, food, and drink. Additionally, sufficient compressive and tensile strength helps ensure that the cement does not break down under normal functional loads.

Other factors, while important, do not directly contribute to the longevity of dental cement in the same way. Color matching is significant for aesthetic purposes but does not influence the physical durability of the cement itself. Ease of manipulation refers to how easy the cement is to work with during application, which, while useful, does not affect its long-term performance. Quick setting time can improve efficiency during procedures but may not directly correlate with the longevity of the cement in the long run. Therefore, resistance to solubility and strength
