自然牙利用比色板及數位光譜儀測量明暗差異探討

比色最重要的目的，就是將補綴物製作出與自然牙幾無差異的顏色。然而現今補綴物的製作卻受到比色板的使用、比色時的條件和環境以及視覺現象所影響而造成誤差，其中變因較大的為比色時的條件及環境，該如何達到良好的比色結果，對於比色方式、儀器運用絕對是技師需要努力的方向。本研究內容在於探討以數位比色光譜儀比色結果為標準，對照初學者使用比色板比色所得之差異。結果顯示男女比色時，在明暗方面有統計學上顯著差異。特別是男生在於齒頸部比色的狀況接近標準值，根據t檢定的結果，p值為0.026。而女生在本體部的比色狀況p值為0.057。在量測明暗方面，有顯著的差異的原因，可能是由於人體眼球的構造對於明暗的反應較色彩靈敏。所以在不受外在環境與客觀條件下，以數位比色光譜儀比色是最佳的選擇。但如果沒有數位比色光譜儀比色，比色者本身與觀測條件及照明光源，都須符合比色流程標準再進行量測，才能得到較準確的結果。

The most important thing about shade matching is patch material to produce exactly the same color of natural teeth. But now the production of patch material has been limited by the usages of shade guides. conditions and environments, as well as the impact of visual phenomena caused by the error. The study using the results of the digital shade spectrograph as the standard, and was intended to explore difference with the traditional usage of control channel for the beginners. The results showed in value there is a statistically significant difference. Especially the men's color comparisons situation of cervical is close to standard value. According to the t-test result, the p-value is 0.026. The women's color comparisons situation of body's p-value is 0.057. The value has the obvious statistical difference is due to the structure of the human eye for the value of the shading is more sensitive than the value of color. Therefore, the judgement values would depend on the external environment and the objective conditions, the usage of digital shade spectrograph is the best choice.
