摘　　要：目的:评价数码摄影技术与视觉比色法在前牙全瓷冠修复中的效果。方法:排除邻牙外形、色泽、位置异常等干扰因素后筛选30名上中切牙缺损或因颜色异常需行冠修复的患者,随机分为A、B 2组,比色后,A组使用VITA 3D-MASTER比色板比色法选择的颜色制作瓷牙,B组利用在尽量相同的时间及环境下拍摄的数码影像照片制作瓷牙,记录。结果:2种比色方法在切端比色结果具有统计学差异(P=0.034),使用数码摄影技术组患者在瓷牙形态、协调性方面患者满意度较视觉比色法高,差异有统计学意义(P=0.041)。结论:单纯使用数码摄影技术在患牙颜色选择上较视觉比色法无明显优势,但可以较好地辅助患牙制作,受一定外因干扰,需结合其他比色方法,临床及科研中应对数码摄影技术的操作环境进行必要的规范,以便获得更加精准的比色结果。Objective：To study the differences of the color matching accuracy between the visual color matching and digital photogra- phy color matching. Methods：Thirty patients whose maxillary middle incisors needed to be restored were enrolled and randomized into A and B groups excluding the interfering factors of appearance,color and position. After color matching,patients in group A used VI- TA 3D-MASTER to choose color while those in group B took photograph by digital camera under the same time and environment, then fabricated all-ceramic crown. Results：There were statistical differences between the two methods in incisor color（P=0.034） and the digital photography color matching got higher satisfaction degree concerning the shape and harmony（P=-0.041 ）. Conclusions：Only using digital photography technology could help the full crown making and it maybe interfered by some factors. Therefore,other meth- ods should be combined in order to get an excellent color matching and necessary standards about the operating environment of digi- tal photography should be set.
