- Abstract
Objective. The aim of this study is to analyze the variation of color among the maxillary anterior teeth. Additionally, this variation has been correlated with the age of the patients. Means and method. One examiner, free of any visual color deficiencies, has studied the chromatic behavior within the maxillary anterior dental group (13-23) for 30 subjects with ages between 23 and 34. With the help of the Vita Easy Shade (Vita Zahnfabrik - Germany), CIEL*a*b* chromatic parameters have been recorded for each tooth. Chromatic differences have been calculated for each set of adjacent teeth. The stated null hypothesis „There is no statistically relevant correlation between patients age and color variation among the maxillary anterior dental group“ was evaluated with the help of the Spearman/Pearson tests. Additional linear regression calculations have been made in order to estimate the color variation among anterior maxillary teeth in relation to age. Within the age limits of the study group, the estimated color variation has been calculated for the minimum age (23), maximum age (34) and medium age (28.5). Results. The correlations show that age is significantly correlated to the variation in dental color for the pairs 13/12, 12/11 and 22/23 (p<0.05). For the remaining pairs of teeth (11/21 and 21/22) the correlation between age and color variation is not relevant. Within the limits of this study, a tendency for chromatic uniformity has been noticed for 12/11, 11/21, 21/22, the differences becoming imperceptible to the human eye (ΔE<2 ) after the age of 33, whereas the canines start to chromatically differentiate from the neighboring incisors around the age of 14-16, the contrast becoming more intense with age. Conclusions. Color is not uniformly distributed among the anterior maxillary teeth, and the chromatic variation is related to patients age. Therefore while restoring the maxillary arch with dentures (complete or partial), the sets of artificial teeth used should respect the color distribution in relation to the patient's age.
