This study aimed to evaluate the effect of sintering temperature on color stability and translucency in zirconia systems with low, high, and ultra-high translucencies.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>This experimental study was conducted on 60 zirconia disks with low, high and ultra-high translucencies (n = 20 per group), each group divided into subgroups to be sintered at either 1450\u00b0C or 1550\u00b0C (n = 10 per subgroup). Baseline color and translucency parameters were measured, the specimens were then immersed in coffee solution for 30 days, and the measurements were repeated post-immersion. Changes in color (\u0394E) and translucency (\u0394TP) were calculated via CIELAB formula and compared by using two-way ANOVA and Tukey\u2019s post hoc test (\u03b1 = 0.05).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Results of two-way ANOVA showed that the \u0394E was significantly different among the three zirconia translucencies (P&lt;0.001), but no significant difference was found between the two sintering temperatures (P = 0.712). Additionally, the interaction between zirconia type and sintering temperature was not statistically significant for \u0394E (P = 0.264). The low-translucency group showed significantly greater \u0394E than the high-translucency and ultra-high-translucency groups (P&lt;0.05), while the high- and ultra-high-translucency groups were not significantly different in this regard (P&gt;0.05). Regarding the \u0394TP, two-way ANOVA showed that the difference was not statistically significant either among the three zirconia types (P = 0.4430) or between the two sintering temperatures (P = 0.4544). Nor was the interaction between zirconia type and sintering temperature statistically significant (P = 0.5505).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>It was concluded that sintering temperature had no effect on color and translucency changes after immersion in coffee. Whereas zirconia type significantly affected the color changes after immersion in coffee; with the higher-translucency zirconia types being significantly more color-stable than the low-translucency zirconia.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0313645","type":"journal-article","created":{"date-parts":[[2024,11,14]],"date-time":"2024-11-14T18:35:32Z","timestamp":1731609332000},"page":"e0313645","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":2,"title":["Effect of sintering temperature on color stability and translucency of various zirconia systems after immersion in coffee solution"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1091-9574","authenticated-orcid":true,"given":"Rashin","family":"Giti","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sina","family":"Mosallanezhad","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2024,11,14]]},"reference":[{"key":"pone.0313645.ref001","first-page":"130","article-title":"Zirconia in dentistry: Part 1.
