Expansion and contraction rates between dental materials and tooth structure caused by temperature change vary. Gaps at the margins allow fluids to enter the space. What is this known as?

Question

Quizplus · Accepted Answer

The gaps at the margins that allow fluids to enter the space caused by expansion and contraction rates are known as percolation. Coefficient of thermal expansion, thermal conductivity, and dimensional change are related to this phenomenon but do not directly address the issue of gaps at the margins.
