ABSTRACT
Dental restorations must not only restore the morphology and the affected functions of the teeth, but it is also important that they do not exert negative effects on the health of the surrounding tissues. There are several different descriptions for biocompatibility in the literature. However, it generally refers to the ability of a material to produce an appropriate host response when applied as intended. Obviously, biocompatibility can be defined as the compatibility of a material with a living tissue/system in that it is not toxic, harmful, physiologically reactive or including immunological rejection. In addition, based on biocompatibility (reaction of the tissue to the biomaterial used), the dental biomaterials used can be classified as biotolerant, bioinert and bioactive . The application in the oral cavity of different types of classic or modern restorations made by different techniques and technologies can induce more or less important reactions, at the level of the whole organism, or limited to the level of the tissues with which they come into contact.
