[Raw] Tooth Discoloration

This dataset was generated in a study where tooth discoloration was measured following exposure to CS, EC aerosol, coffee, red wine, and soy sauce. Whitening treatments were applied following exposure and discoloration was measured. Changes in L*, a*, and b* values for enamel, dentin, and composite resin were measured after exposures and treatments. ΔE values were calculated based on L*, a*, and b*values. This dataset includes single measurements for each sample.本数据集源自一项研究，该研究测定了样本暴露于卷烟烟雾（Cigarette Smoke, CS）、电子烟气溶胶（Electronic Cigarette Aerosol, EC aerosol）、咖啡、红酒及酱油后的牙齿变色情况。研究人员在暴露后施加牙齿美白干预，并于干预后再次测量牙齿变色程度；随后测定了牙釉质、牙本质与复合树脂在暴露及美白处理后的L*、a*、b*值变化，并基于上述三个颜色参数计算了总色差ΔE值。本数据集包含所有样本的单次测量数据。
