The VivaPen delivery form for AdheSE One adhesive allows the material to be applied directly to the restoration.
AdheSE One is a self-etching, light-curing, alli-in-one adhesive for direct restorative treatment procedures. The adhesive is delivered via the VivaPen, which, according to the manufacturer, saves material and allows for easy access to all tooth surfaces.
Ivoclar Vivadent has provided a unique delivery form for AdheSE One. The VivaPen comes with a prebent, replaceable brush cannula, which the manufacturer says allows for easy scrubbing. The rotatable hub is intended for the best positioning of the brush cannula. The manufacturer explains that the VivaPen is activated by pressing the “click” mechanism until the brush cannula is saturated with adhesive.
A single layer of adhesive is then applied to the tooth surface and brushed into the dentin and enamel for 30 seconds. According to the manufacturer, this method of material delivery allows dentists to dispense the exact amount of material needed. When the dentist evaluators were asked to rate the VivaPen compared with bottle or unit dosing, 67% rated it as excellent and 33% rated it as very good. One evaluator said, “Love it! The brush that comes on the pen is excellent as well and I have no problem getting to those hard-to-reach places.”
According to in vitro research conducted by Ivoclar Vivadent, AdheSE One achieved equally high shear bond strengths to enamel and dentin.1 Some of the other adhesives compared in the study exhibited lower bond strengths to enamel than to dentin. An in vivo study of AdheSE One showed a 100% retention rate at 6 months.1 Acknowledging that bond strength to dentin and enamel cannot be thoroughly assessed in the short term evaluation conducted by the Dental Product Shopper evaluators, all of the dentists who participated in this evaluation rated the effectiveness of AdheSE One as very good. As one evaluator noted, “[It’s] too soon to tell, [but] seems good so far.” Dental Product Shopper will follow up with these evaluators and let you know in a future issue how these patients are doing.
According to the manufacturer, because of AdheSE One’s self-etching properties, all areas of the dentin are demineralized but they are not penetrated by monomers. Ivoclar Vivadent says that this efficient infiltration of the dentin significantly reduces postoperative sensitivity. Two of the evaluators rated this product as excellent with regard to postoperative sensitivity, 3 rated it as very good, and 1 rated it as good. One evaluator noted that he observed no problems and another said he had nothing significant to report.
Ease of Use
When the evaluators were asked to rate AdheSE One on ease of use, 1 rated it as excellent, 4 rated it as very good, and 1 rated it as good. All of the evaluators noted that the pen design for delivering the material enhances the ease of use of this product, but 2 noted that the location of the button to dispense the material is in a slightly awkward place.
According to Ivoclar Vivadent, the water solvent and the integrated nanofillers in AdheSE One ensure that a homogenous layer of material is formed when it is applied to the tooth surface. This homogenous layer means that only a single layer of material is needed.
The manufacturer says that the combination of the single layer application and the VivaPen delivery form lead to time savings for the dentist. The evaluators agree. Three evaluators rated AdheSE One as excellent for time savings and 3 rated it as very good. One evaluator said, “I like that you don’t have to dispense into wells and use additional brushes.” Another evaluator commented, “Very good…no more taking a brush in and out of the mouth for more adhesive. Love it.”
When the evaluators were asked to give their overall satisfaction rating for AdheSE One, 5 rated the product excellent to very good and 1 rated it as good. One evaluator said that he found the product “very efficient. No more wasted pools of adhesive left in a plastic dish.” Another evaluator said, “I just love the pen design and the ‘click’ feature. More adhesive instantly. Awesome!”
