For example, water flows easily over sandpaper; however, on wax paper, water beads up and does not flow as readily. Without proper adhesion, microleakage can occur, and the restoration could come out. By understanding why certain chemicals are contained in the materials it may be possible to make an educated assessment as to how the material is likely to behave with respect to handling and function. 2017;26:99.
