摘要:
目的 比较比色板和分光光度计用于牙齿漂白后评估治疗总有效率的差异。 方法 59颗上颌中切牙经35%过氧化氢漂白,分别用Vita classical比色板和CM-700d分光光度计在漂白前后进行牙齿颜色的测量,通过疗效评价标准计算漂白总有效率,利用SPSS17.0统计学软件进行X2检验。 结果 比色板和分光光度计获得的漂白总有效率有统计学差异,P=0.031。分光光度计得到的漂白总有效率高于比色板,分别是97%、87%。 结论 分光光度计测色比视觉比色准确性高,且更全面地描述了牙齿颜色的变化,因此漂白效果的评估应优先选择分光光度计。

Abstract:
Objective To compare the difference between shade guide and spectrophotometer used by evaluating treatment total effective rate after tooth bleaching. Methods 59 maxillary central incisors bleached with 35% hydrogen peroxide. Teeth color measured with Vita classical shade guide and CM-700d spectrophotometer before and after bleaching. Total effective rate calculated by the evaluation standard of curative effect and analyzed for X2 test by SPSS17.0 statistical software. Results The total effective rate of bleaching was statistically difference between shade guide and spectrophotometer, P=0.031. The total effective rate of bleaching with spectrophotometer was higher than shade guide, 97%, 87% respectively. Conclusion The accuracy of color measurement with spectrophotometer is higher than visual colorimetric. And more fully describes the change of teeth color. Thus spectrophotometer should be gave priority to the assessment of bleaching effect.
