**5. Conclusions**

Cytotoxicity screening assays provide a measure of cell death caused by biomaterials. The term cytotoxicity describes the cascade of molecular events that interfere with the macromolecular synthesis, causing specific cellular, functional, and structural damage. Different screening assays are available, and it is crucial to understand the advantages and limitations of the various available assays so that they can be selected for appropriateness and interpreted accurately.
