The aim of this study is to evaluate and compare the color stability of nanoparticles reinforced maxillofacial silicone after disinfection with neutral soap, 4% chlorhexidine, and ozone water.
According to ISO 4823, a metal die was fabricated, and 96 samples were created using Room Temperature Vulcanizing silicone (RTV), Heat Temperature Vulcanizing silicone (HTV), and 3% silicone dioxide nanoparticle-reinforced RTV and HTV silicones. The samples were disinfected using neutral soap, 4% chlorhexidine, and ozone water for 10 minutes, three times a day, for 60 days. The samples were divided into four groups: Group 1 (RTV), Group 2 (3% SiO2 nanoparticle-reinforced RTV), Group 3 (HTV), and Group 4 (3% SiO2 nanoparticle-reinforced HTV). The color stability of the maxillofacial silicones was evaluated before and after disinfection using a UV spectrophotometer. The obtained color stability values were statistically analyzed using two-way ANOVA and Tukey's HSD test. Values were considered significant when p<0.05.
The 3% SiO2 nanoparticle-reinforced HTV silicone showed better color stability compared to HTV and RTV silicones, with the least difference observed in the 3% SiO2 nanoparticle-reinforced RTV.
Ozone water caused the least change in the color of maxillofacial silicone compared to other disinfectant solutions.
本研究旨在评估和比较纳米颗粒增强型颌面硅橡胶在使用中性肥皂、4%洗必泰及臭氧水消毒后的颜色稳定性。
根据ISO 4823制作金属模具，使用室温硫化硅橡胶（RTV）、高温硫化硅橡胶（HTV）以及3%二氧化硅纳米颗粒增强的RTV和HTV硅橡胶制作96个样本。样本分别使用中性肥皂、4%洗必泰及臭氧水消毒10分钟，每天3次，共60天。样本分为四组：第1组（RTV）、第2组（3%二氧化硅纳米颗粒增强的RTV）、第3组（HTV）和第4组（3%二氧化硅纳米颗粒增强的HTV）。使用紫外分光光度计在消毒前后评估颌面硅橡胶的颜色稳定性。所得颜色稳定性值采用双向方差分析和Tukey's HSD检验进行统计学分析。当p<0.05时，数值被认为具有显著性。
与HTV和RTV硅橡胶相比，3%二氧化硅纳米颗粒增强的HTV硅橡胶显示出更好的颜色稳定性，在3%二氧化硅纳米颗粒增强的RTV中观察到的差异最小。
与其他消毒溶液相比，臭氧水导致颌面硅橡胶颜色变化最小。
