Sumario:BACKGROUND: Dental restoration or prosthesis in harmony with adjacent natural teeth color is indispensable part for the successful esthetic outcome. The studies indicate is existence of correlation between teeth and skin color. Teeth and skin color are changed over the aging process. The aim of the study was to explore the role of age on the tooth and skin color parameters, and to investigate the effect of ageing on teeth-skin color correlation. MATERIALS AND METHODS: Total of 225 Saudi Arabian ethnic subjects was divided into three groups of 75 each. The groups were divided according to participant’s age. The participant’s age for Group I, Group II, and Group III was 18-29 years, 30-50 years, and above 50 years, respectively. The tooth color was identified by spectrophotometer in CIE Lab parameters. The skin color was registered with skin surface photography. The data were statistically analyzed with one-way ANOVA and correlation tests with SPSS 18 software. RESULTS: The Group I had the highest ‘L’ value of 80.26, Group III recorded the least value of 76.66. The Group III had highest yellow value ‘b’ at 22.72, while Group I had 19.19. The skin ‘L’ value was highest in the young population; the elder population had the increased red value ‘a’ in comparison to younger subjects. The ‘L’ tooth color parameter had a strong positive linear correlation with skin color in young and adult subjects. While Group III teeth showed the strong positive correlation with ‘b’ parameter at malar region. CONCLUSION: The elder subjects had darker and yellow teeth in comparison with younger subjects. The reddening of the skin was observed as age-related skin color change. The age had a strong influence on the teeth-skin color correlation.
