Context: Color difference between maxillar and mandibular incisors is an anticipated subject, and it will help dentists during color matching. Aim: The aim of this study was to evaluate color differences of the maxillar and mandibular incisors and to find out relationships between gender and age. Materials and Methods: This study was conducted on 125 participants (51 males and 74 females) between 16-63 age groups and totally over maxillar and mandibular 480 healthy teeth by using spectrophotometer. Color differences between teeth were calculated by using ∆E formula. One way ANOVA statistical analysis determined statistically significant differences between maxiller-central and mandibular-canine teeth for ∆L and ∆b parameters (P&lt;0.05). Results: According to t-test result there were not a statistically significant color differences for women and men teeth (P&lt;0.05). Scheffe statistical analysis results showed statistically significant differences between mandibular central and mandibular canine for ∆L parameters on 16-27, 28-39, and 52-63 age groups; for ∆b parameters, there were statistically significant differences between 16-27 and 40-51 age groups (P&lt;0.05). Conclusion: Women have more lighter teeth than men. Maxillar canines are more yellow and Maxillar centrals are more lighter than other incisors. 16-27, 28-39 age groups have more lighter teeth than 52-63 age groups and 16-27 age groups have more yellow teeth than 40-51 age groups.
