Biocompatibility of dental materials

With the long history of use of many materials in dental surgery, biocompatibility concerns are not as great a concern as other issues, such as long-term degradation, mechanical strength problems, and prevention of secondary caries. It is important, however, not to forget that the potential exists for adverse tissue responses to synthetic materials used in repair, augmentation, and repair of natural tissue structures. As new materials and repair techniques become available and the sophistication of cell-level and subcellular response evaluations increases, the concerns to be addressed and the methods to be used may change. The advent of tissue-engineered medical products may mean that new questions must be addressed.
