摘要
目的:对健康汉族成人切牙区牙龈颜色的色度值进行采集和分析,研究人体切牙区牙龈色度学分布。方法:用MINOLTACS-321便携式色差仪采集、分析127例受试者切牙区牙龈色度值,采用SAS软件进行统计学分析。结果:上颌附着龈色度值范围L*24.25-58.88、a*1.72-18.64、b*0.59-10.16;上颌边缘龈色度值范围L*23.14-59.81、a*1.42-16.52、b*0.56-7.99;下颌边缘龈色度值范围L*29.94-60.12、a*1.54-13.74、b*1.22-9.81。上颌附着龈和边缘龈无明度上的差异,但附着龈较边缘龈的牙龈颜色要偏红偏黄许多;下颌边缘龈较上颌边缘龈则明度高,牙龈颜色偏红偏黄。结论:通过此项研究,初步确定了健康汉族成人切牙区牙龈颜色在色空间的分布范围和分布特点。
Objective: To collect and analyze the anterior gingival color of healthy Han nationality, and to study the distribution of human nature gingival color. Methods: The anterior gingival color of 127 subjects were measured with MINOLTA CS-321 portable colorimeter. Data were analyzed by SAS software. Results: The values of L*, a* and b*of maxillary attached gingiva, respectively, were L* 24.25-58.88, a* 1.72-18.64, b* 0.59-10.16; The values of L*, a* and b* of maxillary marginal gingiva, respectively, were 23.14-59.81,1.42-16.52,0.56-7.99; The values of L*, a* and b*of mandibular marginal gingiva were respectively 29.94-60.12,1.54-13.74,1.22-9.81. L* values of mandibular marginal gingiva were higher than the maxillary marginal gingiva, and a*/b* values of mandibular attached gingiva and maxillary marginal gingiva were higher than the maxillary marginal gingiva. Conclusion: By the study, the distribution rule and region of the natural gingival color of healthy Han nationality has been acquired.
