口腔医学专业不同训练层次人员牙比色能力的初步调查

A preliminary study on shade matching ability of dental professionals with different background

目的:使用牙比色训练箱(TTB)对口腔专业不同训练层次操作者的比色能力进行检测,以了解他们比色能力的差异,为医学美容课程设置提供依据。方法:选取排除色觉障碍的口腔医学本科学生、口腔修复工艺(专科)学生、牙科加工中心技师各20名,分别以TTB比色测试模式随机抽取的15个比色标准色标进行测试,使用SPSS17.0软件包统计分析上述3组不同训练层次人员的比色成绩的差异。结果:口腔本科生、口腔修复工艺学生与牙科加工中心技师比色成绩分别是834.04±51.66、859.40±53.31和888.36±48.54;口腔本科生和口腔修复工艺学生之间无显著差异(P>0.05),而牙科技师显著高于口腔修复工艺学生(P<0.05)和口腔本科生(P<0.01)。结论:经过TTB比色测试,不同训练层次人员的牙比色成绩有显著差异。

PURPOSE： To investigate the difference of shade matching ability of dental professionals with different educational background using toothguide training box （TTB）, and provide information for medical esthetics course in dental school. METHODS： Sixty subjects including 20 dental students, 20 prosthodontics technical students and 20 prosthodontics technicians without color blindness were enrolled in this study. Each participant was asked to match 15 standard shade tabs which have been randomly chosen from Vita 3D-Master shade guide. SPSS 17.0 software package was used for data analysis. RESULTS： The scores of dental students, prosthodontics technical students and dental prosthodontics technicians were 834.04±51.66, 859.40±53.31and 888.36±48.54, respectively. There was no significant difference in the sum number of accurate shade matching compared between dental students and prosthodontics technical students （P〉0.05）, but there was significant difference between dental prosthodontics technicians, prosthodontics technical students （P〈0.05）, and dental students （P〈0.01）. CONCLUSIONS： The score of shade matching is significantly different among dental professionals with different background using TTB.
