The total number of samples (45) were divided into three main groups cured according to three curing cycles (The standard short cycle, rapid was subdivided into three subgroup: The control group (without additives), samples prepared with the addition of Nigella Sativa , and samples prepared with the addition of Thyme oil. Color was measured for all the samples. Results were analyzed statistically by (Descriptive statistics, ANOVA and Duncan’s multiple range test) and showed that both additives(Nigella Sativa and Thyme oil) showed significant changes in the color of denture base. conclusion Both additives (Nigella sativa and Thyme oil) showed significant changes in the color of acrylic resin denture base material. The addition of Thyme oil to the samples cured by the regular heat curing cycle showed color change (ΔE=3.376) in relation to the standard (ADA) cycle which is an acceptable range in vitro.
This study were to evaluate the effect of Nigella sativa and Thyme oil on The color of Acrylic Resin Denture Base Material.

Frequently Asked Questions
What was the objective of the study on denture base material?
The study aimed to evaluate the effect of adding Nigella Sativa and Thyme oil on the color stability of acrylic resin denture bases.
How was the color of the samples measured?
Color measurements were performed using the VITA Easyshade device and analyzed according to the CIE L* a* b* color system.
Did the additives cause significant color changes?
Yes, statistical analysis (ANOVA) showed that both Nigella Sativa and Thyme oil caused significant changes in the color of the denture base.
Which additive showed acceptable color change results in vitro?
Thyme oil added to samples cured by the regular heat cycle showed a color change (ΔE=3.376) that is considered within an acceptable range for in vitro studies.
How many curing cycles were tested in the study?
The study divided 45 samples into three main groups based on different curing cycles, including the standard short cycle and rapid curing.
