G5™ works by coagulating the plasma proteins contained within the dentinal tubule fluid. This coagulation forms an initial “plug”, eliminating the movement of fluid within the tubules—the root cause of dentinal sensitivity.
- Aqueous, 5% glutaraldehyde-based desensitizer with 35% HEMA
- Eliminates post-operative sensitivity in posterior composite restorations
- Glutaraldehyde with HEMA shows profound in-vivo antibacterial effect that seems to prevent bacterial growth in tooth/restoration interfaces and can produce gap-free margins
- Eradicates sensitivity under temporary crowns and bridges
- Desensitizes roots
- Does not adversely affect the bond strengths of resin cement to dentin
- Not recommended for use with self-etching cement adhesives
- Eye protection and rubber dam isolation are ESSENTIAL for use with this product
The All-Purpose Desensitizer & Wetting Agent That Won’t Affect Bond Strength
Effective Desensitization of Class I & II Direct Posterior Restorations When Utilizing 4th and 5th Generation Adhesives & a Total-Etch Technique
- Post-operative sensitivity is an ever-present clinical problem with posterior restorations, with studies showing
an incidence rate of up to 63%1. While your patient’s comfort is of paramount importance, the clinician should also be concerned with dentinal hypersensitivity causing added chair time through compromised restorations if an ineffective desensitizing technique is utilized.
Bonding Ability & Strength
- Variations in the depth of etch of phosphoric acid, amount of wetness, degree of penetration of the bonding resin into the collagen matrix, and the amount of coverage and thickness of the bonding layer are just some of the many variables in the total-etch technique that can negatively effect the restoration. In addition, many self-etching adhesives have a tendency to etch enamel ineffectively and form “water trees”, percolations of water that affect the ability to bond effectively. Their lack of versatility with self-cure and auto-cure composites has further complicated efforts to establish a truly predictable posterior restorative technique. G5TM from Clinician’s Choice® is an all purpose desensitizer designed to address the challenges presented by 4th and 5th generation adhesives.
G5 – The Predictable Solution for Effective Desensitization
- G5 is an aqueous, 5% glutaraldehyde-based desensitizer with 35% HEMA (a pre-primer resin) designed for use with 4th and 5th generation adhesives. G5 works by coagulating the plasma proteins contained within the dentinal tubule fluid.
- This coagulation forms an initial “plug” (which can be seen to a depth of 200 microns2), eliminating the movement of fluid within the tubules—the root cause of dentinal sensitivity. In clinical studies, glutaraldehyde has consistently been shown to significantly decrease sensitivity3 on hypersensitive teeth without effecting bond strength between treated surfaces and controls4. Glutaraldehyde has shown little or no effect on retention on crowns luted with zinc phosphate, glass ionomer, and resin-modified glass ionomer cements5, and is one of few desensitizers that will not adversely affect bond strengths of resin cement to dentin6. Glutaraldehyde has an antibacterial effect, protecting the tooth/restoration surfaces from bacteria growth and may prevent secondary caries in cases where microleakage has occurred. Additionally, G5’s sealing effect means you’ll experience gap-free margins.
Bond Longevity
- MMPs, matrix metalloproteinases, are enzymes found in collagen that become active after acid etching. These enzymes gradually degrade the collagen fibers at the dentin/adhesive interface causing diminishing bond strengths. Fortunately, studies have shown glutaraldehyde acts to inhibit the activity of the MMPs, resulting in long-term bond strengths. G5 helps to inhibit the negative affects of MMPs.
