Background: This study intended to determine the colour distribution of the maxillary, central, lateral and canine teeth and to investigate the effect of age and gender on this colour distribution.
Materials and methods : The colour measurements of the maxillary right central, lateral and canine teeth were carried out by the Vita Easyshade V (Vita Zahnfabrik, Bad Sackingen, Germany) spectrophotometer on a total of 202 voluntarily patients including 89 (men) and 113 (women). The age distribution in the study was between 15 and 70 (the average was 31). Grey background colour was used in order to prevent the reflection of the background while performing the colour measurement with the Vita EasyShade V (Vita Zahnfabrik, Bad Sackingen, Germay).
Results: When comparing the L*, a* and b* values of the teeth with the gender; statistically significant difference was not fount between the gender and the L* and b* values (P>0,05) while statistically significant difference was observed between the gender and the a* value (P<0,05).
Conclusions: The tooth colour distribution according to the Vitapan Classical; in the central and lateral teeth it was maximum A2, while it was found to be B3 in the canine teeth. The tooth colour distribution according to the VITA Toothguide 3D-MASTER colour scale; in the central teeth the 2M2 colour was measured most often, in the lateral teeth the 3M2 colour was detected the most often while in the canine teeth the 2M3 colour was measured the most often.
