Aim: To evaluate the change in color of the maxillofacial silicone after curing using a mobile phone colorimeter application. Materials and methods: A two-piece metal mold was fabricated. Twenty five samples were made using M511, maxillofacial silicone. A jig was prepared to hold the mobile phone at a fix distance from the samples. The color was measured for each sample in terms of HSV (hue, saturation, value) with the mobile phone colorimeter application after manipulation and after polymerization of the samples. Data were statistically analyzed using the Student’s paired t test and the software used in the analysis was SPSS 22.0 version. Results: The mean difference of hue was 1.32 ± 2.71, with p value 0.053. Mean differences in saturation was 0.72 ± 2.01, with p value 0.066. Mean differences in value were 2.16 ± 3.11, with a p value 0.002. The measure of value showed statistically significant differences (p < 0.05). Conclusion: There was a significant change in the value of the color of the maxillofacial silicone after polymerization. Clinical significance: Increasing the value of the color by 2–3% at the time of manipulation of the maxillofacial silicone with the use of a mobile phone colorimeter application can help the clinician to reproduce the same color in the final prosthesis after curing to achieve a predictable esthetic outcome for a facial prosthesis.
