【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。
[Abstract]:Objective: to evaluate the effect of digital photography and visual colorimetry in the restoration of anterior all-ceramic crowns. Methods: the shape and color of adjacent teeth were excluded. Thirty patients with upper central incisor defect or need coronal repair due to abnormal color were selected after abnormal location and other interference factors, and were randomly divided into two groups: group A, B, B, after colorimetry. Group A used VITA 3D-MASTER colorimetric method to make porcelain teeth. Group B made porcelain teeth with digital images taken at the same time and environment. Results there was a statistical difference between the two colorimetric methods at the cutting end (P < 0.034). The patients in the digital photography group were in the porcelain tooth shape. In terms of coordination, patient satisfaction was higher than that of visual colorimetry, and the difference was statistically significant (P 0.041). Conclusion: digital photography alone has no significant advantage over visual colorimetry in color selection of affected teeth. However, it can be used to assist the tooth making, and be interfered by some external factors. It is necessary to regulate the operating environment of digital photography in clinical and scientific research in combination with other colorimetric methods. In order to obtain more accurate colorimetric results.
