G-ænial Bond Self-Etching Bonding Agent
GC America Inc.
The HEMA-free formulation of G-ænial Bond makes it efficient and easy to use.
GC America’s G-ænial Bond is a 7th-generation, 1-step, self-etch bonding agent designed to improve bond strength to enamel and dentin. It was designed to provide the option of selective etching (self-etch on dentin and etchand- rinse on enamel), so clinicians can use the most appropriate technique in a given situation to achieve the best result for patients.
To enhance the bond strength to enamel, GC America increased the amount of phosphoric ester monomer, resulting in a pH value decreased from 2.0 to 1.5. In addition, to achieve better permeability to dentin and enamel, a less hydrophobic monomer was used.
Fourteen dentists participated in this Dental Product Shopper evaluation of G-ænial Bond. They rated and commented on such features as ease of use, handling, curing time, and bond strength. They also told us how likely they would be to purchase the product and recommend it to colleagues.
Ease of Use and Handling
The technique guide provided by GC America indicates that the application of G-ænial Bond is basically a 4-step process: apply, wait 10 seconds, air dry 10 seconds, and then light cure. Curing time will depend on the type of light used and the distance from the light tip to the tooth surface.
The ease of use of G-ænial Bond was rated as excellent by 9 evaluators, as very good by 3, and as good by 2. In addition, 7 of the evaluators commented that ease of use was the feature they liked best about the bonding agent. An evaluator from Baltimore with 33 years of experience said, “I believe that, in general, clinicians like the easiest products to use, which would make complications unlikely. So this is a good product.”
With regard to handling, 8 evaluators rated this aspect of G-ænial Bond as excellent, 4 rated it as very good, and 2 rated it as good. An evaluator from Southampton, PA, described “good consistency and easy application” as her favorite features of G-ænial Bond.
Curing time needed for G-ænial Bond is based on the type of light used and the distance from the light guide tip. The amount of curing time necessary ranges from 3 seconds to 20 seconds.
When asked to rate the curing time of G-ænial Bond, 9 rated it as excellent, 4 rated it as very good, and 1 rated it as good. A prosthodontist who has been in practice for 15 years said, “[It] cured well, which sometimes has been a challenge with other bonding agents.” This same evaluator gave G-ænial Bond an overall satisfaction rating of very good and said he would probably purchase it in the future and recommend it to colleagues.
Initial Bond Strength
According to GC America, clinical testing of G-ænial Bond has shown higher shear bond strengths to enamel than some other 1-step and 2-step self-etch bonding agents. In addition, dentin bond strength testing showed that G-ænial Bond outperformed other bonding agents.
While the evaluators are unable to test bond strength in their practices, we did ask them to rate their reaction to the initial bond strength of the product. Six evaluators rated initial bond strength as excellent, 6 rated it as very good, and 2 rated it as good.
At the end of the evaluation, the evaluators were asked how likely they would be to purchase G-ænial Bond in the future and recommend it to their colleagues. Thirteen evaluators said they would definitely or probably recommend it to colleagues, and 11 said they would definitely or probably purchase it. When asked for their overall satisfaction with G-ænial Bond, 8 evaluators rated it as excellent, 4 rated it as very good, and 2 rated it as good. An evaluator from North Royalton, OH, said the product was “Very easy to use. G-ænial Bond left a clearly visible shiny, primed surface. We also noted no post-op sensitivity after use.” Another evaluator said, “I am switching to this product immediately.”
