REALITY’s Top Choices
All tests performed in the Reality Research Lab are performed by dentists-not students or researchers-in a way that stimulates actual clinical procedures as closely as possible.
Embrace WetBond, Pulpdent Corp.
Innovative chemistry allowing it to bond to wet tooth structure could lead to more durable adhesion, but its rather low self-cured bond strength is still a concern.
G-Cem, GC America Inc.
Choice of automix syringes or capsules makes it as convenient to use as any product in this category and clinical results using capsules are impressive, but syringe material longevity still needs to be proven.
RelyX Unicem, 3M ESPE
Longevity as the first self-adhesive resin cement gives it extra credibility and the clicker dispensing makes it available to all those without a triturator, but the lack of automixing is a definite drawback.

The DENTAL ADVISOR’s Top Choices
Self-adhesive resin cements eliminate the need for separate etchants and primers for bonding ceramic and metal restorations to tooth structure. These cements are available in tooth-colored, translucent and opaque shades and are dual-cured.
Selected comments from our consultants…
Clearfil SA Cement, Kuraray America
“One of the easiest resin cements ever.”
“Endo tip is great-easiest post cementation clean-up I’ve ever had.”
RelyX Unicem, 3M ESPE
“We use RelyX Unicem more often than any other cement in the clinic.”
G-Cem Automix, GC America Inc.
“Easy to mix, dispense and clean up after setting.”

THE DENTAL ADVISOR Clinical Tip
Self-adhesive resin cements have a lower incidence of sensitivity than adhesive or traditional crown and bridge cements. Marginal staining of self-adhesive resin cements has been reported to be lower than that of traditional cements. Self-adhesive resin cements bond to tooth structure and other materials with low (5-8 MPa) to medium (8-15 MPa) bond strengths. The separate use of a bonding agent is not recommended. Although bonding agents may be compatible with self-adhesive resin cements, their use makes the manipulation more complicated and may not dramatically improve bond strength to tooth structure. Flexural strength and modulus measured when these cements are light-activated are generally higher than when they are self-cured. When needed, higher bond strengths can be obtained with esthetic and adhesive resin cements that are bonded with separate bonding agents and primers.
