J Pak Dent Assoc Jan ;19(2):115-9.

OBJECTIVE: The objectives of this study was to compare the CIE L*a*b* values of cervical, middle and incisal segments of permanent maxillary central incisors using standardized digital camera and computer software (Adobe Photoshop®) . METHODOLOGY: Maxillary anterior teeth of one hundred subjects were photographed under the same light effects and images were imported into the computer. The CIE L*a*b* values of the cervical, middle and incisal segments (2-mm area in the center of each segment) of permanent maxillary central incisors were obtained by using the Adobe Photoshop (version 7). SPSS version 12 was used for data analysis. Statistical significance was determined by using ANOVA at confidence interval 95%, P<0.05 was considered significant. RESULT: There is significant difference in L*, a* and b* values of cervical, middle and incisor segments of maxillary central incisor (p<0.001). Color differences in Cervical/Middle, Cervical/Incisal and Middle/Incisal were significantly different (p = 0.025) CONCLUSION: The shade of cervical, middle and incisal segments of permanent maxillary central incisor is significantly different from each other.
