There are many potential applications of nanomaterials indentistry.2 Composite resins have been widely used in restorations of dental caries;3 however, it is estimated that approximately 50% of prepared restorations need to be remade, the secondary caries is one of the most frequent causes of failure,4 and the use of nanomaterials could decrease the incidence of these complications. Thus, the application of nanomaterials can bring numerous benefits in dentistry, especially in caries prevention; however, there is an important question about the safety of these materials for the nervous system. In the study by Feng et al1 a vast array of nanomaterials types and their major applications were outlined. View original article by Feng and colleagues.
