Venus Pearl with iBond Total Etch and iBond Self Etch (1 yr)

Consultants’ Comments

• “Fillings blend perfectly.”
• “Versatile composite – works everywhere in the mouth.”
• “Reliable restorative material.”
• “Holds its polish.”

Description

Venus Pearl is a universal, nano-hybrid composite based on the chemistry of Venus Diamond but with a creamier consistency. Venus Pearl is suitable for all classes of anterior and posterior restorations and is designed to produce a durable, highly esthetic result with a long-lasting, high luster polish. Venus Pearl is available in both syringe and unit dose (PLT) delivery in 27 shades. iBOND Total Etch is a light-cured adhesive used in conjunction with phosphoric acid etchant. It contains nanofillers in an ethanol solvent and can be applied as one coat. iBOND Self Etch is a light-cured, self-etching, one-component bonding agent. Light curing time for both adhesives is 20 seconds. iBOND is available in both 4 mL bottles and single-dose delivery.

Purpose

The purpose of this evaluation was to monitor the one-year clinical performance of Venus Pearl restorations bonded with iBOND Total Etch and iBOND Self Etch.

Clinical Evaluation Protocol

• 190 Venus Pearl restorations were placed; 169 restorations were recalled during the first year after placement.
• Anterior and posterior restorations were placed (Figure 1).
• Restorations were bonded with iBOND Total Etch and iBOND Self Etch (Figure 2).
• At recall, restorations were evaluated for resistance to fracture/chipping, esthetics, resistance to marginal discoloration, wear resistance, lack of sensitivity, and retention.
• Restorations were evaluated on a 1-5 rating scale: 1 = poor, 2 = fair, 3 = good,    4 = very good, 5 = excellent.

Clinical Observations

Resistance to Fracture/Chipping
Resistance to fracture and chipping was excellent with Venus Pearl (Figure 3). Of the 169 restorations recalled, only one, a Class II filling on a second molar, fractured and required replacement. No chipping was observed.

Esthetics
Esthetics of Venus Pearl was rated excellent in both anterior and posterior applications (Figure 3).
Resistance to Marginal Discoloration
Venus Pearl exhibited excellent resistance to staining at the margins of the restorations (Figure 3). Five of the recalled restorations (3%) showed marginal staining. Four of these were minor, requiring no treatment; one involved recurrent caries at the margin.
Wear Resistance
No visible signs of wear were noted on the Venus Pearl restorations recalled (Figure 3).
Lack of Sensitivity
When patients were questioned about sensitivity at their recall appointments, excellent results were reported (Figure 3). There was only one instance of sensitivity – a Class II Venus Pearl/iBOND TE restoration was replaced and an area of incomplete bonding was discovered at that time.
Retention
The overall retention rate of the Venus Pearl restorations in this evaluation was 99% (Figure 3). Two Class V restorations on second molars (on the same patient) debonded. These restorations were bonded with iBOND TE and were found to be missing nine months after placement. The other restorations were intact.

Conclusions

Venus Pearl used with iBond Total Etch and iBond Self Etch received excellent ratings for resistance to fracture/chipping, esthetics, resistance to marginal discoloration, wear resistance, lack of sensitivity, and retention at one year. Venus Pearl/iBond received a 99% clinical performance rating.
