Tooth color assessment

Abstract

Sažetak. Boja zuba u dentalnoj medicini značajno utječe na doživljaj cjelokupne estetike zubi i lica. Percepcija boje ovisi o mnogim čimbenicima, kao što su ljudski faktor, osvjetljenje, okolina, boja pozadine i drugi optički fenomeni. Odabir boje u dentalnoj medicini najčešće se vrši vizualno, pomoću tvorničkih ključeva boja koji se temelje na tonu boje, zasićenosti ili svjetlini. Boje iz ključa uspoređuju se s bojom zubnog niza pacijenta. Takav način odabira boje vrlo je subjektivan te je tako odabranu boju teško reproducirati. Stoga su kreirane objektivne, instrumentalne metode određivanja boje pomoću različitih uređaja, kao što su digitalne kamere, kolorimetar i spektrofotometar. Boja zuba odabrana ovim metodama daje rezultate koji su kvantificirani, objektivizirani, lako ponovljivi i moguće ih je reproducirati u dentalnom laboratoriju.Ključne riječi: estetika; percepcija boje; zubi Abstract. The teeth color in dental medicine significantly affects the overall aesthetics of the teeth and face. Color perception depends on many factors, such as human factor, lighting, environment, background color, and other optical phenomena. Choosing the color in dental medicine is most often done visually using the factory-made color shade guide that is based on the tone of color, saturation or brightness. Colors from the prefabricated shade guide are compared to the color of the dental arch of the patient. Such a color assessment mode is very subjective and the selected color is difficult to reproduce. Therefore, objective and instrumental methods of determining the color were created using different devices such as digital cameras, a colorimeter and a spectrophotometer. Tooth color selected by these methods give results that are quantified, objectified, easily repeatable and reproduced in dental laboratory.
