Current dental adhesives systems. A narrative review

Area of Science:

• Dental Materials Science
• Biomaterials Engineering
• Adhesive Dentistry

Background:

• Adhesive dentistry relies on materials that bond effectively with tooth structures.
• Adhesive systems are critical for modern dental restorations.
• Understanding material chemistry and tissue interaction is key to successful bonding.

Purpose of the Study:

• To outline the current state of adhesive systems in dentistry.
• To emphasize the chemical characteristics and interaction modes of adhesives with enamel and dentin.
• To discuss factors influencing the selection of appropriate bonding procedures.

Main Methods:

• Review of contemporary adhesive systems.
• Analysis of chemical properties and interaction mechanisms.
• Classification of adhesives into "etch-and-rinse" and "self-etch" categories.
• Consideration of enamel and dentin anatomical differences.

Main Results:

• Adhesive systems vary in their chemical composition and interaction with dental tissues.
• "Etch-and-rinse" adhesives often perform better on enamel.
• "Self-etch" adhesives may be more suitable for dentin bonding.
• Different bonding procedures impact bond quality and clinical outcomes.

Conclusions:

• Selecting the right adhesive system requires understanding its chemistry and interaction with specific tooth tissues.
• Clinical handling and knowledge of morphological changes are essential for successful bonding.
• Careful consideration of patient-specific factors is vital to prevent restoration failure, secondary caries, and pulp damage.
