Abstract
Introduction The color of the gingiva was thought to be valuable assist in determining the color of the missing central incisors. The aim of this study was to investigate the correlation between CIE L*a*b* color coordinates of central incisor teeth and attached gingiva. Materials and methods Two hundred patients participated in this study, the color coordinates L*a*b* of the central incisors and attached gingiva was determined by the clinical spectrophotometer Shadepilot, Pearson's correlation and multiple regression were used to assess whether one can predict the value of the tooth color coordinates based on the values of gingival color. Results The results of current work showed significant correlation of the teeth to gingival color, except for maxillary central incisor a*, and showed that gingival color can be used to predict the color of missing central incisor teeth. Conclusion Within the limitation of the study, it was concluded that the significant correlation found between central incisors and gingival color. Keywords: Attached gingiva color, CIELAB color system, Spectrophotometer, Tooth color.
