摘要

目的:本研究旨在探讨不同光照条件对牙科专业人员视觉阴影匹配准确度的影响。本研究还确定了牙科医生的色度匹配能力是否存在性别偏见。方法与材料:60名牙科执业医师参与本研究。所有参与者都使用石原的测试进行色盲测试。随机选择两个经典的vita shade标签,并隐藏其识别码。参与者被要求在三种不同的光照条件下使用完整的vita阴影指南来匹配这些选择的标签——自然光、临床光和使用市售的手持式阴影匹配设备。选择的阴影标签被记录下来,正确的匹配被计算出来。采用统计学分析:采用Mann Whitney ' U '检验和Kruskal Wallis ' H '检验对数据进行统计学分析。结果:手持配影灯在视觉配影准确度上优于临床配影灯。自然光优于临床光照,差异有统计学意义(p =0.001)。男性受试者的准确率低于女性受试者,但差异无统计学意义(p>0.05)。结论:标准化手持式配荫器的使用效果与自然光相当,建议在无自然光条件下进行准确的配荫。

Influence Of Different Lighting Conditions On Accuracy Of Visual Shade Matching By Dental Professionals
Aims : The purpose of this study was to assess the influence of different lighting conditions on accuracy of visual shade matching by dental professionals. This study also determined any gender bias in shade matching abilities of dental practitioners. Methods and Material : Sixty dental practitioners participated in this study. All participants were tested for color blindness using Ishihara’s tests. Two classical vita shade tabs were randomly selected, and their identification codes were concealed. The participants were asked to match these selected tabs by using a complete vita shade guide under three different light conditions-natural light, clinical light, and using the commercially available hand-held shade matching device. The chosen shade tabs were recorded, and the correct matches were counted. Statistical analysis used : The data were statistically analyzed using Mann Whitney ‘U’ test and Kruskal Wallis ‘H’ test. Results : Hand-held shade matching light was better than clinical light in terms of accuracy of visual shade matching. Natural daylight was statistically significantly better than clinical light (p =0.001). Accuracy among male participants was lower as compared to female participants, but the difference was not statistically significant (p>0.05). Conclusions : The use of a standardized hand-held shade matching device is comparable to natural daylight, and is recommended for accurate shade matching in absence of natural lighting conditions.
