Background: Denture lining materials are widely used in prosthodontic treatment and management of traumatized
oral mucosa. A contaminated prosthesis can provide a source of cross-contamination between patients and dental
personnel as well as a cause for denture stomatitis. Therefore, denture disinfection has been recommended as an
essential procedure for maintenance of a healthy oral mucosa. This study investigated the effect of SOLO
disinfectant solution on some properties of different denture lining materials.
Materials and methods: Three different solutions were used in this study; SOLO disinfectant solution, sodium
hypochlorite solution, and water on three types of acrylic denture lining materials; hot cure, cold cure, and soft
acrylic resin. Twenty seven disk-shaped samples were used to evaluate the color stability and forty five rectangular
samples were used for testing the surface micro hardness and surface roughness of the different denture lining
materials. Data measurements of the color stability, surface hardness, and surface roughness were analyzed and
Results: The color stability for the tested denture lining materials was insignificantly affected (p>0.05) by the immersion
in the SOLO disinfectant solution. There was a highly significant difference (p< 0.01) in the surface hardness of the hot
cure while it was insignificant (p>0.05) for cold cure denture lining materials when immersed in the SOLO disinfectant
solution. For surface roughness there was no significant difference (p>0.05) by immersion in SOLO disinfectant solution
for the different denture lining materials.
Conclusions: Based on the results of this study SOLO disinfectant solution produced no adverse effect on the color
stability, surface hardness, and surface roughness of the hot cure, cold cure, and soft acrylic denture lining materials
