Synopsis

Recently, much attention has been paid to bio-active restorative materials and liners, focusing on their mineralizing ability or stimulation of apatite formation. However, bio-active functions useful for dental treatment/care are diverse. In addition to promotion of remineralization and hard tissue formation, control of bacterial infection, prevention of inflammation, and promotion of healing and tissue regeneration can be included as functions beneficial to obtain better treatment results and enable effective disease control/prevention.

S-PRG filler, a glass powder having a pre-reacted glass-ionomer phase on the surface of fluoroboroaluminosilicate core glass, is one of the highly advanced dental technologies. It releases six different ions F^–, BO₃^3-, Sr²⁺, Na⁺, Al³⁺, and SiO₃^2- at high concentrations. Due to such ion release characteristics, S-PRG filler exhibits multiple bio-active functions such as tooth strengthening, promotion of mineralization, acid neutralization, inhibition of bacteria and fungi, and enhancement of cell activity. Accordingly, S-PRG filler can be utilized for various dental treatment and prevention/care in different material forms. Notably, in the field of pediatric dentistry, composites/adhesives, coating resin, fissure sealant, polishing gel, and toothpaste containing S-PRG filler are of great interest for achieving restoration with preventive effects and effective caries prevention/management regimen.

The present lecture describes the concept of bio-active dental materials and the functions of S-PRG filler. Clinical benefits and usefulness of various commercially available and experimental materials containing bio-active S-PRG filler for pediatric dentistry will be highlighted.
