| Summary: | Bioactive glasses (bg) are ceramic materials
whose chemical composition allows them
to induce and conduct tissue mineralization. As these glasses can be obtained with
the sol-gel method and in nanometric particle sizes, their indication has been extended
and enhanced.
The antibacterial properties of bg are outstanding: they are possible given the release
of ions, which alkalinizes the medium, acting on the bacterial colonies.
The medical and dental applications of
these materials are wide, with an emphasis on bone regeneration, remineralization of hard dental tissues and treatment
of hypersensitivity. However, as they are
materials with an amorphous chemical
structure, their mechanical properties
are not good, this being their main limitation for clinical application in restorative dentistry. In this sense, scientific
research has focused on determining
the possibility of including bg in various dental materials as a way to combine
bioactivity with appropriate mechanical
properties.
So far, it has not been possible to determine the proportion and methodology
necessary to include bg in dental materials without altering their clinical behavior, which is why further research is
necessary.
