Consultants’ Comments

• “Body shades can be used alone or layered.”
• “Great handling characteristics – not sticky at all.”
• “Good consistency for establishing interproximal contacts.”
• “Material is radiopaque.”

Description

GC KALORE is a low-shrinkage, universal nanofilled composite indicated for use in all classes of direct restorations. This composite combines a new monomer from DuPont along with UDMA but contains no Bis-GMA. GC KALORE contains High Density Radiopaque (HDR) pre-polymerized fillers. GC KALORE is available in 26 shades, including 15 universal shades, five opaque shades and six translucent shades. Each shade is available in 0.3 g capsules or 4 g syringes. Curing time is 20 seconds with a standard halogen or LED light for most shades.

Clinical Evaluation Protocol

• 178 GC KALORE restorations were placed and monitored over a three-year period.
• Recall ratings for 87 restorations were recorded and are included in this report.
• Of these restorations, 93% were posterior and 7% were anterior.
• At recall the following categories were assessed on a scale of 1-5 (1=poor, 2=fair, 3=good, 4=very good, 5=excellent).

Clinical Observations

Resistance to Fracture/Chipping

GC KALORE proved to be very durable during the three-year recall period (Figure 1). Over 98% of the restorations evaluated received an excellent rating. Of 87 restorations, one had a slight chip that did not require treatment and one fractured, requiring replacement. The fractured filling was a Class II restoration on tooth #20.

Esthetics

Ninety percent of restorations were rated excellent for esthetics at three years (Figure 1). The remaining 10% were rated very good and showed minor discoloration or lack of blending with the tooth. Superior esthetics was obtained when shades were layered at placement. GC Kalore blends well and has a high quality of finish and polish at placement; restorations maintained an excellent finish over the three-year period.

Resistance to Marginal Discoloration

The majority of restorations placed with GC KALORE were resistant to staining and marginal discoloration. Ninety-five percent of restorations evaluated received an excellent rating (Figure 1). Four restorations showed slight staining at the margin.

Wear Resistance

Only one restoration placed with GC KALORE was observed to have slight wear at year three. That restoration was a Class I filling on a second molar. The remaining 86 recalled GC KALORE restorations rated very good or excellent for wear resistance.

Conclusions

GC KALORE universal composite had excellent ratings for resistance to chipping/fracture, resistance to marginal discoloration and wear resistance over a three-year period. Shades blended well and excellent esthetics was maintained. GC KALORE received a 98% clinical performance rating.
