Glass ionomer cements
Glass ionomer cements are a new kind of filling materials. SICs are low-toxic, have high strength and satisfactory aesthetic characteristics, and also have anti-caries activity. SICs are capable of "healing" teeth, they can absorb fluoride from toothpaste and then give it back to the tooth, strengthening and hypermineralizing the surrounding dentin filling.
-
Depending on the scope of application, SICs are divided into:
- SIC for permanent fillings;
- SIC for gaskets and sealing of fissures (quick-setting);
- SITs used for sealing root canals;
- SITs, used in fixation of orthopedic dental structures.
-
Advantages of SIC:
- high degree of adhesion to tooth tissues and other filling materials;
- biological compatibility with tooth tissues;
- low probability of cracks between the filling and the tooth;
- are able to give the tooth fluoride and other trace elements, promoting its remineralization, have an antibacterial effect
SIC is cheaper than composite filling material, easy to use.
Composites are often used to restore permanent teeth. However, composites cannot solve all the problems of treating permanent "unformed" teeth. Anatomy, biochemistry, and tissue physiology of both temporary and permanent teeth in children differs from similar indicators in adults. Filling materials used to fill baby teeth contain fluoride (glass ionomer materials), which prevents the development of secondary caries (caries that occur under an existing filling). SIC is most often used in the treatment of caries in children. There are also colored materials used for filling milk teeth (blue, yellow, purple, green).
