text: Calcium hydroxide has significant drawbacks; the low elastic modulus and low compressive strength of calcium hydroxide cavity liners restricts their usage to thin layers in specific areas, which is not critical to the support of restorations.31,38 Calcium hydroxide liners have low thermal conductivity, but they are usually not used in thick enough layers (≤0.5 mm) to provide thermal protection;20 therefore, thermal protection should be provided with a separate base.
