What is a common complication associated with deep amalgam restorations?

• A. Infection
• B. Pulpal irritation
• C. Tooth sensitivity
• D. Material wear

Answer: (B)

The selection of pulpal irritation as a common complication associated with deep amalgam restorations is justified since these restorations involve significant removal of tooth structure, potentially exposing or coming close to the dental pulp. When the restorative material is placed deeply, it can lead to thermal, chemical, or mechanical irritation of the pulp tissue due to its proximity. Amalgam itself, while a stable material, may not provide adequate thermal insulation when placed on large or deep cavities, thus increasing the risk of pulpal inflammation or sensitivity. In contrast, while infection can be a risk in various dental procedures, it is less commonly associated specifically with the placement of deep amalgam restorations unless there is pre-existing decay or if the procedure is not carried out under sterile conditions. Tooth sensitivity can occur, but it is often a temporary issue that may resolve as the tooth adapts to the new restoration. Material wear is pertinent to all restorative materials but does not singularly refer to the complications stemming from a deep amalgam restoration process itself. Hence, pulpal irritation stands out as a primary concern directly linked to the deep placement of amalgam.
