歯のシェードセレクションにおけるデジタル法と視覚法の比較：光補正装置下での検討

A segmental shade discrepancy between digital and visual methods in the maxillary central incisors is of interest. Sixty-four participants aged 18-45 with intact central incisors were assessed. Shade determination at the cervical, middle and incisal thirds was performed using the VITA Easy shade V spectrophotometer and the 3D Master shade guide under a standardized light-correcting device. Distinct shade variations were noted between the digital and visual methods, reflecting the inherent polychromatic nature of natural dentition. Thus, we show the importance of adopting a combined, segmental approach to shade selection to enhance accuracy and ensure superior esthetic results in clinical practice.
