Abstract
Izbor boje zuba je najmanje definiran pravilima. Terapeuti vrlo često pojednostavljuju izbor boje i ograničavaju se na nekoliko nijansi. Iako su zubi najčešće bijele boje, njezine nijanse mogu znatno varirati i bitno utjecati na estetski dojam koji stvara osmijeh. Dakle, ukupna boja pojedinog zuba nije samo rezultat miješanja boja dentina i cakline, već i drugih optičkih svojstava koja se razlikuju između ovih zubnih tkiva. Na prirodnu boju zubi utječe i boja kože, kao i korištenje ruža ili sjajila za usne. Uza sve to, boja zuba ovisi o okolnoj svjetlosti, te individualnoj percepciji boje od strane promatrača. Iz svega nabrojenoga očito je da je određivanje boje subjektivan postupak, te su i pogreške neizbježne. Zato su se na tržištu pojavili uređaji s ciljem objektivizacije određivanja boje. Danas se metode određivanja boje dijele na vizualne i strojne. Vizualno određivanje boje obavezno se radi na dnevnom svjetlu, a sama boja se određuje prema ključu boja različitih proizvođača. Osim vizualne usporedbe, boja se može određivati korištenjem računalnih uređaja koji se temelje na spektrofotometrijskim ili kolorimetrijskim metodama i koji softverskim programima obrađuju dobivene podatke i iscrtavaju karte površine zuba sa nijansama koje im odgovaraju. S obzirom da obje metode, vizualna i strojna, imaju svoje prednosti i nedostatke, idealno bi bilo koristiti obje metode pri određivanju boje zuba i tako minimalizirati mogućnost pogrešnog odabira.

Parallel abstract (English)
Selection of tooth colour is the least defined by rules. Usually, therapists simplify the colour selection and limit themselves to only few shades. Teeth are usually white colour, but shades of white may vary and create significant influence on the smile impression. Therefore, entire perception of colour of a single tooth depends not only on mixing shades of dentin and enamel, but other optical characteristics between these dental tissues too. Skin colour and usage of lip – stick or lip – gloss also has influence on the tooth colour. Tooth colour also depends on ambient light and individual perception of colour by the observer. Considering all, it’s obvious that selection of tooth colour is subjective procedure, and because of that mistakes are common. Because of that, company invented devices whose aims are to determine colour objectively. Today, we have two methods for selecting tooth colour: visual and digital. Visual method considers colour selection in daylight and the colour itself is determined by shade guide from different manufactures. Besides of visual method, we can also use digital devices to select tooth colour. Digital methods are based on spectrophotometric or colorimetric method. Digital devices use software programs to process received data and draw maps of tooth surface with shades that suit them. Both methods, visual and digital, have advantages and disadvantages and because of that it would be ideal to use both methods to select correct tooth colour. As result of that, possibility of mistakes would be minimized.
