Background: The aim of the present study was to evaluate the color stability
of temporary crown materials fabricated by 3 different methods in 3 different
immersion liquids.
Methods and materials: A total of 72 disc-shaped specimens were prepared using
printable temporary crown material (Temp Print, GC), acrylic milling disc
(Vipi Block Trilux, VIPI), and conventional self-curing acrylic material (Temdent
Classic, Schütz Dental). Specimens per material were divided into three
groups (n=8) according to immersion liquid (distilled water, tea, and coffee
solution). After the specimens were stored in distilled water for one-week, initial
color values measured with a spectrophotometer (Vita Easyshade Advance
4.0, Vita). The color values were also measured 72 hours after immersion. The
color change values between data were calculated based on CIEDE2000 formula.
The results were analyzed using two-way analysis (ANOVA) of variance.
Results: The ΔE00 values were significantly affected by the fabrication methodacrylic
resin duo and immersion liquid (p<.05). The ΔE00 values in the printed
group were significantly higher than conventional and milled groups (p<.001).
When the effect of immersion liquid was evaluated, the highest mean ΔE00
value (1.8) was seen in the coffee solution. There was a significantly difference
between the groups immersed in distilled water and tea (p=.013), distilled water
and coffee (p<.001), tea and coffee (p=.035).
Conclusion: 3D printed temporary crown materials showed more discoloration
than the milled and conventional self-curing temporary crown materials. The
colors of all material groups varied statistically significantly depending on the
type of immersion liquid used.
