What is a potential consequence of insufficient condensation in dental restorations?

Insufficient condensation in dental restorations can lead to marginal leakage, which refers to the gap that can form between the restoration material and the tooth structure. When the restoration is not adequately condensed, it may not fill the cavity preparation completely, allowing for spaces that can collect saliva, bacteria, and food particles. This creates an environment conducive to secondary caries and other complications, as the seal that prevents these materials from entering the tooth structure is compromised.

In contrast, increased bond strength, reduction of postoperative sensitivity, and improved esthetics would typically be the result of proper condensation, as adequate pressure helps to eliminate voids and ensures a better adaptation of the material to the tooth structure, enhancing its overall performance and longevity. Therefore, marginal leakage stands out as a significant consequence of inadequate condensation.
