Coming to terms with the options in adhesive dentistry can be confusing. Even within the generations, systems differ in number of steps and components and technique compatibility, and the progression from one generation to the next doesn’t necessarily reflect improvements in strength or simplicity. Therefore, you must choose carefully among the available options with your patients’ needs and your own skill set in mind.
Many still consider 4th generation total-etch adhesives (etch-rinse-prime-adhesive resin, or multi-bottle systems) the ones to beat due to their ability to provide deep, strong, predictable, long-term bond to enamel on self-cure, dual-cure, and light-cured composites as well as indirect restorations.
The self-etch systems of generation 6 do not require rinsing, are less technique sensitive, and minimize postoperative sensitivity, but their bond strength to dentin and enamel is not considered equal to that of generations 4 and 5.
The all-in-one, single-bottle self-etch products of generation 7 require neither mixing nor rinsing systems and their bond strengths are similar to those of generation 6, but they are not compatible with self-cured composite resin cements. And, finally, as a dual-cured self-etch adhesive for direct and indirect restorations with self-cured as well as light- and dual-cured restorations, generation 8 offers the advantages of a simplified approach to be used under appropriate clinical conditions.
Adhesive dentistry is key to minimally invasive, esthetic, pain-free, and tooth-preserving dental restorations. As an essential element of clinical restorative dentistry, the appropriately selected adhesive can make a real difference in your daily practice.

Shofu Dental Corp.
BeautiBond from Shofu is a 7th generation all-in-one adhesive that enables etching, priming, and bonding in one single application. Unique dual adhesive monomers work independently, achieving equal bond strength to dentin and enamel, comparable to 6th generation adhesives.
At a thickness of 5 microns, BeautiBond only requires a single coat and no agitation, resulting in shorter working time thus minimizing postoperative sensitivity. BeautiBond has a HEMA-|free composition, and a gentle pH balance resulting in virtually no gingival blanching. The convenient unit dose delivery ensures fresh product every time with no mixing, while also minimizing waste from contamination or chairside spills.
With this technology, biocompatibility, and durability, BeautiBond is an all-in-one adhesive that enables etching, priming, and bonding in a single application. It all adds up to a better, faster, and easier result for the clinician and the patient.
Brush&Bond from Parkell is a self-etching, self-priming 4-META based bonding system that is ideal for adhesive procedures, desensitizing teeth and protecting tooth structure against microleakage. It features a unique dual initiator system that responds to all currently available curing lights. It permanently seals the tubules to prevent sensitivity and protects the vulnerable pulp from pathogens that penetrate compromised margins.
Brush&Bond’s strong tripolymer, plus the polymerization enhancers in the special activator brushes included in the kit, create a thinner, harder, significantly more wear-and-acid-resistant protective shield for the tooth that prevents decalcification. In fact Brush&Bond reinforced dentin is up to 10 times harder than dentin coated with conventional bonding agents, so it resists damage during later removal of the temporary and seating of the definitive crown.
GC America Inc.
G-ænial Bond from GC America Inc. is a universal seventh-generation, one-step self-etching bonding agent with improved bond strength to both enamel and dentin. Additionally, in the rare case where it is indicated to etch uncut enamel and the phosphoric acid etching hits the dentin, the bond strength to dentin will not be degraded.
This product was designed specifically for the “selective etching” technique, meaning that bond strengths will be enhanced no matter what technique you use. With an exceptionally thin bonding layer for great esthetics and easy clean-up, G-ænial Bond has very simple handling properties. With improved shear bond strength to both dentin and enamel, and 30 seconds from application to finish, this is an excellent choice for all bonding needs.
The Future of Bonding in Dentistry
Standardize your clinical protocols for effective delivery of adhesion with ALL-BOND UNIVERSAL® from BISCO. A light-cured, single-component dental bonding agent that combines etching, priming, and bonding in a single bottle, this truly universal adhesive simplifies restorative procedures by adapting to self-, total-, and selective-etch techniques. Other single-bottle adhesives may need more than 1 bottle for indirect restorations, but with ALL-BOND UNIVERSAL, no additional activator is required, providing you a significant cost savings and guaranteed clinical effectiveness.
Compared to other new universal adhesives, this product is less acidic and is designed to be more hydrophobic and less permeable. The culmination of over 30 years of adhesive research, ALL-BOND UNIVERSAL is an indispensable part of any dental practice. It is the only adhesive needed for all bonding procedures.
