One of many challenges in cosmetic dentistry is to accomplish appropriate and satisfactory reproduction of natural shade of teeth and in that way to make successful restoration. The procedure of choosing a shade can be performed using visual method or by an instrument. The kind of shade guide, individual ability to choose shades and conditions the choice is made under, all have influence on reliability and accuracy of the procedure. Therefore, it is necessary to introduce instrumental color determination in everyday work. The instrumental color determination method considers use of a spectrophotometer, a colorimeter and a digital camera or even the combination of all three in shade matching. The purpose of this article was to present all amenities and advantages of the instrumental color determination in shade matching through the demonstration of the clinical performances of an intraoral spectrophotometer VITA Easyshade Compact device. VITA Easyshade Compact device provides fast and reliable measuring and gives results that are not influenced by the conditions under which the shade was chosen or by the person who made choice. Shade matching using a spectrophotometer meets all the requirements for choosing the shade by vision, therefore it is recommended for clinical work. Jedan od izazova estetske stomatologije je i odgovarajuca i zadovoljavajuca reprodukcija boje prirodnog zuba, sto je znacajan faktor uspeha buduce restauracije. Postupak izbora boje moguc je primenom vizuelne i instrumentalne metode. Vrsta primenjenog kljuca boja, individualna sposobnost odabira boje i uslovi u kojima se izbor boje odvija mogu uticati na pouzdanost i preciznost postupka, pa je stoga neophodno uvodjenje instrumentalne metode u svakodnevni rad. Radi objektivizacije terapijskog postupka, instrumentalna metoda odredjivanja boje zuba podrazumeva primenu spektrofotometra, tristimulusnih kolorimetara, digitalnog analizatora boja, kao i njihovu kombinaciju. U ovom radu prikazane su pogodnosti i prednosti primene instrumentalne metode u postupku odredjivanja boje zuba kroz prikaz klinickih performansi intraoralnog spektrofotometra. Aparat VITA Easyshade Compact omogucava brzo i pouzdano merenje, pokazuje rezultate koji su potpuno nezavisni od uslova u kojima se izbor boje vrsi i iskljucuje subjektivnost terapeuta. Odredjivanje boje zuba primenom spektrofotometra ispunjava sve preduslove za izbor boje u skladu s fiziologijom kolornog vida i moze se preporuciti u rutinskom klinickom radu.
