This process can stop early carious lesions from getting worse. It helps keep the tooth structure strong, which is key in minimally invasive dentistry.

Fluoride-Releasing Materials

Fluoride-releasing materials are vital for remineralization and caries arrest. Glass ionomer cements and fluoride composites release fluoride ions. These ions help form fluorapatite and hydroxyapatite crystals in teeth.

This makes teeth stronger against acid and stops carious lesions from spreading.

Calcium Phosphate-Based Materials

Calcium phosphate-based materials are also great for remineralization and caries arrest. Amorphous calcium phosphate (ACP) and hydroxyapatite (HA) release calcium and phosphate ions. These ions move into the tooth and help form new mineral crystals.

This process is called remineralization of enamel and dentin. The materials blend well with the tooth structure, boosting their effectiveness.

Antimicrobial and Anti-Biofilm Properties

Bioactive materials with antimicrobial and anti-biofilm properties help prevent and manage dental caries. They support a less invasive way of treating teeth. Silver-based materials like silver diamine fluoride and silver nanoparticles are great at fighting antimicrobial activity against bacteria that cause cavities. They stop biofilm from forming and slow down the growth of harmful bacteria. This can help stop cavities from getting worse.
