Sažetak
Digital photography has become an indispensable part of modern medicine and
dentistry. In the initial stages, digital single lens reflex cameras were used in medicine and dentistry
and were considered the golden standard. In recent years, smartphones have become available and
enable adjusting of camera settings. The aim of the study was to examine color accuracy on digital
photographs taken with a smartphone and the possibility of applying a simple protocol for shooting
digital photographs in daily clinical work. The study was conducted on 45 subjects, and a total of 15
JPEG photographs using three smartphones were taken. Five photographs with different lighting
modes were taken with each smartphone and the CIE L*a*b* values were measured. Difference in color
(dE) was calculated. The results showed that different lighting conditions and different smartphones
did affect color values in this study. The CIE L*a*b* values measured on digital photographs using
different smartphones and different illuminations differed significantly (p<0.01). There was significant
difference in color between digital photographs in different illuminations and measurements of the
natural teeth (p<0.01). Digital photo protocol taken with a smartphone cannot be used as an accurate
method for digital determination of tooth color in dentistry.
