Influence of Light Conditions and Light Sources on Clinical Measurement of Natural Teeth Color using VITA Easyshade Advance 4.0® Spectrophotometer. Pilot Study

“…Korištenje ključa boja podložno je subjektivnosti liječnika dentalne medicine i na rezultat mogu utjecati različite varijable kao što su svjetlost, kut iz kojeg se zub promatra te alat kojim se pri procjeni boje služi (3,4). Čimbenici kao što su zamor oka, dob i emocije te neki lijekovi, također utječu na interpretaciju promatrača i njegov podražaj na određenu boju (2,6). Najvažniji faktor koji utječe na percepciju boja jest vrsta svjetlosti u prostoriji koja može varirati prema tipu, snazi i kutu upada (1).…”

“…U usporedbi s ljudskim okom, odnosno klasičnim nači-nom određivanja boje, ustanovljeno je da je spektrofotometar 33 posto točniji i objektivniji u 93,3 posto slučajeva (2). S obzirom na važnost točne procjene boje pri obavljanju estetskih zahvata u stomatologiji, uz osnovni ključ boja mnogi autori predlažu i kombiniranu uporabu digitalnih metoda određivanja boje (12,13).…”

“…Dependent on the type of the procedure and the tools the dentist and the dental technician are using, the tooth color measurement can be divided in two groups: classical (conventional) using shade guides and a digital one (2)(3)(4). The use of shade guides to measure tooth color is a subjective process and many factors may affect the results, such as the illumination, the angle of view of the tooth and the tools used (3,4).…”

Factors such as fatigue, ageing and emotions as well as some medication also influence the observer's understanding of color stimulus (2,6).…”
