| Popis: | Summary Objectives: To establish the strength of color relation among the maxillary central incisor, lateral incisor and canine teeth by using digital photography. This relation might be useful for the color reconstruction of the missing part of a tooth from the color obtained from neighboring teeth. Methods: The L p a p b p values of the maxillary incisors and canines were determined in 100 subjects. Paired t-tests, Pearson correlations and linear regression analyses were used to describe the relation of the L p a p b p values between the three teeth for each segment (cervical, middle and incisal). Results: The mean L p a p b p values of the canines differed statistically significantly from the values of the central incisors ðp , 0:001Þ except for L p and a p values in the cervical segment between the lateral incisor and canine. The color differences between the incisors were statistically significant in fewer cases. The relation in color was the highest between the cervical segments of the three teeth, with respect to L p (r ¼ 0:45–0:65; p , 0:001), b p (r ¼ 0:49–0:55; p , 0:001), and a p (r ¼ 0:38–0:61; p , 0:001), and no relation was found between the incisal segments of central incisor and canine. Significance: There is a relation in color between the maxillary incisors and canines, which is stronger between the cervical than between the middle and incisal segments. Therefore, the color prediction is most reliable when the cervical parts of the teeth are used. Q 2004 Academy of Dental Materials. Published by Elsevier Ltd. All rights reserved. |
