Une cam\u00e9ra effectue une spectroscopie de la lumi\u00e8re r\u00e9fl\u00e9chie et un ordinateur calcule, couleur par couleur, ce qu\u2019aurait \u00e9t\u00e9 le spectre r\u00e9fl\u00e9chi si la dent avait \u00e9t\u00e9 \u00e9clair\u00e9e sous le spectre de l\u2019illuminant D65.<\/p>\n

Pour sch\u00e9matiser, l\u2019appareil de prise de teinte \u00ab sait \u00bb combien son spectre contient d\u2019\u00e9nergie d\u2019\u00e9clairement pour chaque couleur par rapport \u00e0 la v\u00e9ritable lumi\u00e8re du jour. Il applique donc \u00e0 la valeur r\u00e9fl\u00e9chie par la dent une correction par une r\u00e8gle de 3.<\/p>\n

Comme la surface d\u2019une dent pr\u00e9sente de multiples variations de couleurs, de tr\u00e8s nombreuses mesures doivent \u00eatre effectu\u00e9es. C\u2019est l\u2019op\u00e9rateur qui devra d\u00e9terminer les points \u00e0 mesurer. Et pour cela, il doit voir sans se tromper les diff\u00e9rences de couleurs. Si sa vision est tromp\u00e9e par la source d\u2019\u00e9clairage g\u00e9n\u00e9ral, ses choix de mesure ne seront pas pertinents ou incomplets.<\/p>\n

Comme par ailleurs, la vision de la couleur de la dent ne peut \u00eatre per\u00e7ue que sous une lumi\u00e8re multidirectionnelle (comme la lumi\u00e8re ext\u00e9rieure), il y a toutes les chances que les mesures de la cam\u00e9ra obtenues par une lumi\u00e8re unidirectionnelle soient tronqu\u00e9es.<\/p>\n

De l\u2019avis des sp\u00e9cialistes, l\u2019utilisation de ces outils est tr\u00e8s complexe et sujette \u00e0 un tr\u00e8s fort risque d\u2019erreur.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row type=“in_container“ full_screen_row_position=“middle“ column_margin=“default“ scene_position=“center“ text_color=“dark“ text_align=“left“ top_padding=“60″ overlay_strength=“0.3″ shape_divider_position=“bottom“ bg_image_animation=“none“ shape_type=““][vc_column column_padding=“no-extra-padding“ column_padding_position=“all“ background_color_opacity=“1″ background_hover_color_opacity=“1″ column_link_target=“_self“ column_shadow=“none“ column_border_radius=“none“ width=“1\/1″ tablet_width_inherit=“default“ tablet_text_alignment=“default“ phone_text_alignment=“default“ overlay_strength=“0.3″ column_border_width=“none“ column_border_style=“solid“ bg_image_animation=“none“][nectar_gradient_text heading_tag=“h2″ color=“extra-color-gradient-1″ gradient_direction=“horizontal“ text=“La prise de couleur : une op\u00e9ration \u00e0 haut risque“][vc_row_inner column_margin=“40px“ top_padding=“0″ text_align=“left“][vc_column_inner column_padding=“no-extra-padding“ column_padding_position=“all“ background_color_opacity=“1″ background_hover_color_opacity=“1″ column_shadow=“none“ column_border_radius=“none“ column_link_target=“_self“ width=“1\/1″ tablet_width_inherit=“default“ overlay_strength=“0.3″ column_border_width=“none“ column_border_style=“solid“ bg_image_animation=“none“][vc_column_text]Elle comprend l\u2019appr\u00e9ciation des masses \u00e9mail, de la micro-g\u00e9om\u00e9trie des surfaces, de la luminosit\u00e9 de l\u2019\u00e9mail, de la saturation de la couleur, de la teinte de la dentine.<\/p>\n

Cela impose que l\u2019oeil fonctionne dans les meilleures conditions d\u2019\u00e9clairement pour voir sans erreur tout au long de la journ\u00e9e.<\/p>\n

Il le pourra uniquement sous le spectre de lumi\u00e8re et dans les conditions directionnelles de la lumi\u00e8re naturelle.<\/p>\n
