Background and Objectives: Polymethyl methacrylate (PMMA) is currently the material of choice for denture base fabrication, that it has the advantages of good pigment wettability, high gloss and so on.
Uses of natural stains (amaranth and vanilla) cheap and available in our country instead of the synthetic stains with heat cure acrylic resin denture base material for matching with natural human gingiva. Materials and Methods: Ninety samples were prepared of pink heat cure acrylic resin VertexTM material, fifteen samples with natural additives and seventy five samples with synthetic Vertex acrylic stainTM. The color of samples and gingival color of 24 healthy young participate were measured by Vita Easyshade device then compared between them. Statistical analysis was done by special designed program prepared for this study in Mat lab program 2010 that calculate the color difference between all the measurements that appeared only the (ΔE) that ≤ 6.8. Results: Results showed that (ΔE) ≤ 6.8 between some of natural and synthetic stains matched in relation to color of patients' gingiva, and some natural stains matched the color of the patients' gingiva. Conclusions: The results approved can be using the natural stains vanilla and amaranth instead of the synthetic Vertex acrylic stains that is clinically acceptable compared in relation to patients.
Key Words: Natural stains, Vanilla, Amaranth, PMMA.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This study aims to evaluate the effectiveness of natural stains, amaranth and vanilla, as substitutes for synthetic acrylic stains in denture base fabrication. The objective is to assess the color match of denture bases fabricated using these natural stains compared to those fabricated using synthetic stains and the natural gingiva color of patients.
- Evaluation of natural stains (amaranth and vanilla) as alternatives to synthetic stains for denture base fabrication.
- Assessment of color matching between natural stains and synthetic stains in relation to the natural gingival color of patients.
- Exploration of the feasibility and clinical acceptability of using natural stains in denture base fabrication.
- Investigation of the color difference (AE) between denture base samples fabricated with natural and synthetic stains and patients' gingiva.
Zusammenfassung der Kapitel (Chapter Summaries)
The study begins with an introduction, outlining the current use of polymethyl methacrylate (PMMA) as the material of choice for denture base fabrication due to its advantages like good pigment wettability and high gloss. The importance of achieving natural-looking restorations, which involves selecting the appropriate shade and reproducing the color accurately in the prosthesis, is emphasized. The study then delves into the use of colored pigments, including synthetic stains, to enhance the esthetics of restorative materials. The potential toxicity of synthetic stains and the increasing importance of natural coloring agents are discussed, leading to the introduction of amaranth and vanilla as natural stain options.
The Materials and Methods section details the preparation of denture base samples using both natural and synthetic stains. The study utilized Vertex™ pink heat-cured acrylic resin denture base material, with different concentrations of amaranth, vanilla, and synthetic Vertex acrylic stains. Color measurements were conducted using a Vita Easyshade device, and data analysis was performed using a specially designed program in MATLAB 2010.
