Dental bonding agents have significantly transformed restorative dentistry. These materials help achieve strong adhesion between restorative composites and the tooth structure, ensuring long-lasting results and improved patient outcomes.
Bonding agents, also known as dental adhesives, are critical components used in restorative procedures to connect filling materials with the enamel and dentin. They play a key role in ensuring the durability of fillings, veneers, crowns, and other dental restorations.
Focused on enamel bonding using basic monomers.
Minimal adhesion to dentin and poor clinical outcomes.
Aimed to bond to the smear layer of dentin.
Improved over the 1st generation but still weak bond strength.
Introduced dentin conditioning and priming.
Multiple components required more steps but improved bond durability.
Separate etch, primer, and adhesive steps.
High bond strength and durability—considered the gold standard.
Technique-sensitive and time-consuming.
Etch is separate, but primer and adhesive are combined.
Less time-consuming and user-friendly.
Suitable for both direct and indirect restorations.
Combines etching and priming in one bottle, followed by adhesive.
Less post-operative sensitivity.
May provide lower bond strength to enamel compared to total-etch systems.
All-in-one system: etchant, primer, and adhesive in a single bottle.
Fast and convenient for the practitioner.
Simplifies the bonding process but may vary in bond strength performance.
Compatible with self-etch, total-etch, and selective-etch techniques.
Contains functional monomers and nanofillers for stronger, more flexible bonding.
Designed for use on various materials including enamel, dentin, metal, and ceramics.
Generation Steps Etching Type Bond Strength Notes 4th 3-Step Etch-and-Rinse High Reliable, gold standard 5th 2-Step Etch-and-Rinse Moderate–High Primer & adhesive combined 6th 2-Step Self-Etch Moderate Primer + etchant combined 7th 1-Step Self-Etch Variable All-in-one convenience 8th 1-Step Universal High Advanced versatility
The choice of bonding agent depends on the clinical situation, operator preference, and desired bond strength. While some clinicians prefer the consistency of 4th generation systems, others opt for the efficiency of newer self-etch or universal adhesives.
