sealant

This term describes a material designed to create a physical barrier against fluids or gases. It is typically used in construction and automotive repair to ensure a tight fit between two surfaces, often filling irregular gaps that a simple gasket cannot cover.

In a medical or dental context, the term refers to a specialized resin used as a preventative measure. This application focuses on occlusion and protection rather than structural bonding, creating a smooth surface to inhibit the accumulation of debris.
