Effects of Disinfection Methods on the Color Stability of Precolored and Hand-Colored Maxillofacial Silicone: An In Vitro Study

Table 2

Mean and standard error of color change (∆E) for four disinfection methods regardless of the type of intrinsically colored silicone.

Disinfectant	Mean	Standard error	n	Post hoc test (Tukey HSD test)
				Pair	value
Distilled water (DW)	0.55	0.05	20	DW/CHX	<0.001
2% chlorhexidine solution (CHX)	1.77	0.13	20	DW/CHXS	<0.001
Chlorhexidine liquid soap (CHXS)	1.27	0.11	20	DW/AS	0.136
Antibacterial liquid soap (AS)	0.83	0.09	20	CHX/CHXS	<0.001
				CHX/AS	<0.001
				CHXS/AS	0.006
