To evaluate the influence of gender and level of experience on shade matching quality.
A study was simultaneously performed at 15 universities located in 9 countries. A total of 614 color normal participants completed all phases of the experiment. Among them, there were 305 females and 309 males, 319 dental students and 295 dental professionals. A lecture on color matching in dentistry was given to all participants. Initial training was performed using Toothguide Trainer software (TT), while Toothguide Training Box (TTB) was used for both training and testing of participants' shade matching results. The test task was to successively match 15 shade guide tabs with the corresponding shade guide. The shade matching score for each participant was computed as a sum of color differences (SigmaDeltaE(ab)(*) score) between target tabs and selected tabs. Lower scores corresponded to better shade matching results and vice versa. Means and standard deviations were calculated. Mann-Whitney U test was used for statistical analysis of the data (alpha=0.05).
The mean shade matching score (S.D.) for all participants was 41 (21). The score for female and male participants was 38 (20) and 44 (21), respectfully (p<0.001). The difference in scores between dental students, 42 (20), and dental professionals, 39 (21), was not statistically significant.
Within the limitations of this study, females achieved significantly better shade matching results than males, indicating that gender plays an important role in shade matching. The level of experience was not found to be significant factor in shade matching.
评估性别和经验水平对比色质量的影响。
在9个国家的15所大学同时开展一项研究。共有614名色觉正常的参与者完成了实验的所有阶段。其中,女性305名,男性309名,牙科学生319名,牙科专业人员295名。为所有参与者举办了一场关于牙科比色的讲座。最初使用Toothguide Trainer软件(TT)进行培训,而Toothguide Training Box(TTB)用于参与者比色结果的培训和测试。测试任务是依次将15个比色板与相应的比色指南进行匹配。每个参与者的比色分数计算为目标色板与所选色板之间的颜色差异总和(SigmaDeltaE(ab)(*)分数)。分数越低表示比色结果越好,反之亦然。计算均值和标准差。使用曼-惠特尼U检验对数据进行统计分析(α=0.05)。
所有参与者的平均比色分数(标准差)为41(21)。女性和男性参与者的分数分别为38(20)和44(21)(p<0.001)。牙科学生的分数为42(20),牙科专业人员的分数为39(21),两者之间的分数差异无统计学意义。
在本研究的局限性范围内,女性的比色结果明显优于男性,表明性别在比色中起重要作用。未发现经验水平是比色中的重要因素。
