Purpose: This study evaluated color stability of Dentca 3D-printed denture teeth, in comparison to color stabilities of four conventional types of denture teeth, upon being immersed in various colorants.

Materials and methods: Four types of conventional prefabricated denture teeth (Surpass, GC, Artic 6, Heraeus Kulzer, Premium 6, Heraeus Kulzer, Preference, Candulor), 3D-printed denture teeth (Dentca); and Z250 (Filtek Z250, 3M ESPE) were prepared for testing. The samples were immersed in erythrosine 3%, coffee, cola, and distilled water (DW) at 37¡ÆC. Color change (¥ÄE) was measured by spectrophotometer before immersion and at 7, 14, and 21 days after immersion. One-way analysis of variance was performed along with Tukey¡¯s honestly significant difference multiple comparisons test (P<.05).

Results: No great difference was observed between the color change of Dentca denture teeth and that of conventional denture teeth in most cases (P>.05). The color change of Dentca denture teeth immersed in erythrosine 3% was greater than that of Surpass (¥ÄE = 0.67 ¡¾ 0.25) after 1 week; Artic 6 (¥ÄE = 1.44 ¡¾ 0.38) and Premium 6 (¥ÄE = 1.69 ¡¾ 0.35) after 2 weeks; and Surpass (¥ÄE = 1.79 ¡¾ 0.49), Artic 6 (¥ÄE = 2.07 ¡¾ 0.21), Premium 6 (¥ÄE = 2.03 ¡¾ 0.75), and Preference (¥ÄE = 2.01 ¡¾ 0.75) after 3 weeks (P<.05).

Conclusion: A color change was observed in Dentca denture teeth when immersed in some colorants; however, the maximum value of ¥ÄE for Dentca denture teeth was within the clinically acceptable range.
