Lipstick influence on teeth colour appearance

Abstract

Background and aim. A beautiful smile with white and shiny teeth is nowadays a must, according to aesthetics norms. The color of the lips, with or without lipstick, may influence the appearance of the teeth color. The objective of the study was to evaluate the influence of the lipstick on the tooth color appearance.
 Methods. Four female patient smiles were photographed from the frontal view with five different colored lipsticks. Each photo was evaluated by 100 observers and noted from 1-dark to 6 -white. Data were statistically analyzed with dedicated software.
 Results. The majority of the observers noted with lower grades the nude lipstick color photos and with higher grades the red and purple ones.
 Conclusion. Within the limitation of the study, the surrounding (the lipstick) has an important influence on the appearance of the tooth color.

Influence of depth and translucency on the color matching of single-shade resin composites: An in vitro study

“…The OC and VU may have a difference in value level, since OC had a darker appearance (lower value) in relation to restorations performed with VU, which had a lighter appearance (higher value) [48]. Colors with higher values tend to generate more harmonic aspects to the human eye [49], which probably explains the better color matching scores obtained to VU in the visual analysis. In this way, a greater color difference value (ΔE 00 ) cannot always mean an esthetically unfavorable restoration, since this greater color difference may be related to tooth whitening.…”
