CIE L*a*b* Color Analyses of Anterior Maxillary Teeth According to Gender and Localization
Abstract
Objective: This study aimed to investigate the distribution of color values of the anterior maxillary teeth of a Turkish population in the CIE L* a* b* color space by gender and right-left localization variables.
Material-Method: The study was carried out on 434 dental students aged 18-22 years with upper intact central, lateral, and canine teeth. Three consecutive measurements were achieved by a dental spectrophotometer (VITA Easyshade, VITA Zahnfabrik, Germany) from the labial one-third centers to get the median CIE L* a* b* values. To evaluate the difference in color, [(∆L*)²+ (∆a*)² + (∆b*)²]½ formula was used. Maxillary right-left side localization and gender variables were used to classify the data. Kolmogorov Smirnov statistical analyses were used to confirm normal distribution. The data did not exhibit a normal distribution, so Mann Whitney U, Kruskal Wallis, and Wilcoxon tests were used, and these data were expressed as median (min-max). IBM SPSS V23 (IBM, New York, USA) statistical program was used for statistical analyses (p<0,05).
Results: L* a* b* analysis of canine, lateral and central teeth according to gender variable showed that L* values in canine, lateral and central incisor groups were higher in females (p=0.03, p<0,001, p<0,001 respectively). The a* parameter showed higher values in males for canine, lateral and central incisors (p=0.001, p<0,001, p<0,001 respectively). The b* parameter also showed higher values in males for all canine, lateral, and central incisor teeth (p=0.001, p<0,001, p<0,001 respectively). When the resultant ΔE values examined according to the gender variable, canine teeth of male and female participants showed a statistical difference (p=0.008), while lateral and central incisors showed no statistical difference (p=0.105, p=0.129 respectively). Based on the right-left localization variable, L* (Right L*: 79,7 - Left L*: 80,2 p<0,001), and a* parameters showed statistical higher (Right a*: -0,1 / Left a*: -0,2 p=0,020) values in general. The ΔE values among right and left canines, lateral, and central incisors (ΔE =2.67, ΔE=2.94, ΔE=2.14 respectively) also exhibited statistical difference (p<0,001).
Conclusion: CIE L*a*b* color values of teeth in the anterior
maxillary region in a young Turkish population are affected by gender and
right-left localization variables.
