| description | Background and Aim: Tooth color assessing is very important in esthetic dentistry. The aim of this article was to study tooth color prevalence of 20-30-year-old patients and also presentation of a simple method for color assessment .
Materials and Methods : One thousand fifty nonsmoker volunteers (501 men). In a light, distance and angle constant condition the left maxillary incisors were photographed with a digital camera (Canon G9) using a retractor. The pictures were studied with Adobe Photoshop CS5 software. The color of the middle 1/9 of the tooth was measured in L*a*b* system. In the exact above condition vita pan classical shade guide was photographed in direction of neutral background. These pictures were studied with Adobe Photoshop CS5 and L*a*b* average was measured for the middle 1/9 of each sample. After measurement of ∆E* for each person and vita pan classical shade guide, minimum ∆E* was chosen for each tooth as the color of that tooth. Finally, the effect of colored liquid drinks was assessed .
Results : The most popular findings were A3.5 (16.85%) A3 (14.85%) and B1, B2 (9.8%). The results of this study showed that the L* average in nonsmokers who drank colored liquids more than twice a day in comparison to noncolored liquid users was lower. The a* and b* average in this group was higher than noncolored liquid users .
Conclusion : The most common findings were A3.5 (16.85%) A3 (14.85%) B1, B2 (9 . 8%). Tooth color assessment with a digital camera and computerized study is simple and cheap but very sensitive . |
