Aim: the aim of this case report was to evaluate instrumental and visual color match of two single shade resin-based com- posites in human extracted teeth before and after bleaching treatments. Methods: two extracted human posterior sound teeth were used. Round shaped V class cavities (2x2x4mm) were prepa- red buccally 2mm away from the CEJ. Two single shade resin composites (ES-Essentia Universal, GC and CL-Clearfill Maje- sty ES2 Universal, Kuraray) were used for the restorations. To- oth color was measured 1mm beside the cavity and in the cen- ter of the restoration using a spectrophotometer (VITA Easysha- de V, VITA Zahnfabrik). Visual analysis were carried out by 16 calibrated observers and differences were graded as 0:excel- lent match; 1:very good match; 2:not so good match; 3:obvious mismatch; 4:huge mismatch. Teeth were then bleached using 40% H2O2 (Opalescence Boost PF, Ultradent) and instrumental and visual evaluations were replied after 24 hours. Results: at baseline, both ES restoration and tooth showed an A3 VITA scale grade, and respectively A2 and C2 after blea- ching. Color match visual analysis showed a mean value of 0.25 both prior and after bleaching. At baseline, both CL resto- ration and tooth showed an A4VITA scale grade, and respecti- vely A3 and C3 after bleaching. Color match visual analysis showed a mean value of 0.87 before and 0.31 after bleaching. Conclusions: within the limits of a single case report, both composites seem to have excellent color match properties with the surrounding tooth structure, from both instrumental and visual points of view.

Abstract

Aim: the aim of this case report was to evaluate instrumental and visual color match of two single shade resin-based com- posites in human extracted teeth before and after bleaching treatments. Methods: two extracted human posterior sound teeth were used. Round shaped V class cavities (2x2x4mm) were prepa- red buccally 2mm away from the CEJ. Two single shade resin composites (ES-Essentia Universal, GC and CL-Clearfill Maje- sty ES2 Universal, Kuraray) were used for the restorations. To- oth color was measured 1mm beside the cavity and in the cen- ter of the restoration using a spectrophotometer (VITA Easysha- de V, VITA Zahnfabrik). Visual analysis were carried out by 16 calibrated observers and differences were graded as 0:excel- lent match; 1:very good match; 2:not so good match; 3:obvious mismatch; 4:huge mismatch. Teeth were then bleached using 40% H2O2 (Opalescence Boost PF, Ultradent) and instrumental and visual evaluations were replied after 24 hours. Results: at baseline, both ES restoration and tooth showed an A3 VITA scale grade, and respectively A2 and C2 after blea- ching. Color match visual analysis showed a mean value of 0.25 both prior and after bleaching. At baseline, both CL resto- ration and tooth showed an A4VITA scale grade, and respecti- vely A3 and C3 after bleaching. Color match visual analysis showed a mean value of 0.87 before and 0.31 after bleaching. Conclusions: within the limits of a single case report, both composites seem to have excellent color match properties with the surrounding tooth structure, from both instrumental and visual points of view.
