Abstract

Laminate veneer restorations for discolorations of light (L), medium (M), and heavy (H) degree, T I and OII type IPS Empress with varying light transmission, were employed with varying thicknesses of 0.5, 0.8 and 1.0mm, and the effect of different colors of adhesive resin cement on tooth color was investigated.<BR>The conclusions were as follows:<BR>1. For T I, when the target color was A 2, the color appearance was improved at 1.0mm; Yellow Brown (YB) was selected for M and H at 0.8mm and YB for H.<BR>Color appearance was not improved regardless of the choice of cement in any of the discolored samples when the thickness was 0.5mm. When the target color was B 2, no color appearance was improved by any type of cement in any discolored sample.<BR>2. For OII, at 0.5mm and 0.8mm when the target color was A 2, YB was selected for all descolored samples; at 1.0mm, YB was selected for M and H in which color improvement was identified. Color improvement was identified when the target color was B 2. At 0.8mm, Medium Opaque (MO) was selected for L. At 1.0mm, Opaque White (OW) and MO were selected for the same.<BR>3. When A 2 was the target color, YB was selected for OII. When B 2 was the target color, OH was selected along with an opaque cement with a lower Value (L*) than YB, such as OW or MO. It was found that the color appearance was satisfactory and that OII was usable in laminate veneer restorations of discolored teeth.
