TI  - Economical and easy methods of smoke stain removal from
maxillofacial prostheses
AB  - Aim: Service life of a maxillofacial prosthesis is too short especially because of color
instability. This study aimed to investigate the effects of hand soap and chlorhexidine
gluconate mouthwash on the color of maxillofacial prosthesis after exposure of cigarette
smoke.
Materials and Methods: Sixty specimens were fabricated from a maxillofacial silicone
material. Two groups (n=20) were pigmented intrinsically mimicking dark and fair tone
skin and one group was not pigmented for control. All the specimens were exposed to
cigarette smoke in a closed apparatus designed for the study. Color measurements of
the specimens were performed before and after smoke exposition by using a spectrophotometer. Half of all the specimens (n=30) consisting of dark, fair and non-pigmented
ones was rubbed with liquid hand soap and the other half was immersed in chlorhexidine gluconate mouthwash (0.12% chlorhexidine digluconate). Color measurement was
repeated after cleaning process. Color differences were calculated both CIELab (∆E*ab)
and CIEDE2000 (∆E00) color measurement formulas.
Results: Color groups had significantly different color change values in terms of ∆E00
and ∆E*ab after exposition to smoke and cleaning methods (p < 0.001). The effect of
soap and chlorhexidine on color change values did not differ from each other (p=0.284
for ∆E00, p=0.312 for ∆E*ab). The interaction of color groups with cleaning methods
was statistically insignificant (p=0.962 for ∆E00, p=0.550 for ∆E*ab). ∆E00 and ∆E*ab
values showing color alteration between initial color and after cleaning were significantly
different in groups (p < 0.001).
Conclusion: Cleaning process using hand soap and chlorhexidine gluconate mouthwash
succeed to return the color of stained silicone to the initial color.
