<dc:description>[EN]Purpose. The purpose of this clinical study was to determine the color coordinates of healthy&#xd;
gingival papillae and compare them according to sex, age, dental hygiene, and smoking habits, to&#xd;
compare the color coordinates of the papillae to other gingival zones, and to present a valid set of&#xd;
pink ceramic specimens for use in subjective color selection with the gingival papillae.&#xd;
Material and methods. Color coordinates of the attached gingiva and interdental papillae&#xd;
adjacent to the maxillary incisor were recorded by using spectrophotometry (Spectroshade; MHT&#xd;
Optic Research) in 62 White participants (124 papillae). To determine which color specimens best&#xd;
represented the interdental papillae, according to the acceptability thresholds (AT), 2 published&#xd;
databases were used: 15 validated ceramic gingival specimens and 133 ceramic gingival&#xd;
specimens. MANOVA was used for comparisons of color coordinates, and the coverage error&#xd;
was calculated to evaluate the guide.&#xd;
Results. The color-coordinate ranges of the interdental papillae were: L*: 42.2 to 57.5; a*: 16.8 to&#xd;
30.6; and b*: 11.2 to 18.1. Statistically significant differences were found between all gingival zones&#xd;
for all color coordinates (P&lt;.05). The interdental papillae were less yellow than the middle zone of&#xd;
attached gingiva and the free gingival margin, and redder than the mucogingival line. Using the&#xd;
Euclidean formula, the coverage error of the 15-specimen gingival guide was 2.71.&#xd;
Conclusions. The gingival papillae of women were significantly lighter than of men, and the b*&#xd;
coordinate was higher in the papillae of smokers than non-smokers. Age or dental hygiene did not&#xd;
significantly affect interdental papillae color coordinates. Color differences exceeding the AT&#xd;
between the interdental papillae and each of the 3 attached gingival zones were found in a large&#xd;
part of the population. The 15 specimens were useful for subjective shade selection with the&#xd;
interdental papillae.</dc:description>
