What type of restoration is most likely to cause issues due to improper cement choice?

Deep restorations are particularly prone to complications arising from improper cement selection due to several factors. When a restoration is deep, it is often close to or within the pulp chamber or involves significant dentin. This proximity necessitates careful consideration of the cement used, as the material must provide adequate support, seal, and biocompatibility.

If an inappropriate cement is chosen, it may not create a tight seal, leading to microleakage. This leakage can allow bacteria and fluids to enter, increasing the risk of secondary caries or pulpitis. Furthermore, deep restorations are subject to more significant forces due to their location in the mouth and the dynamic nature of chewing. Using a cement that cannot withstand these forces or does not bond well to the tooth structure can compromise the restoration's integrity, leading to issues such as debonding or fracture.

In contrast, shallow and direct restorations generally engage less of the tooth structure and often do not extend close to sensitive pulp tissues, rendering them less susceptible to the negative consequences of cement choice. Provisional restorations are meant for temporary use, and while appropriate cement selection is still critical, the urgency is often lessened compared to long-term, functional deep restorations. Thus, the intricacies associated with
