Objectives: Due to their aesthetic appeal and translucent properties, clear thermoplastic retainers have become increasingly popular. However, ensuring their proper maintenance and cleaning is a significant challenge. It is essential to prevent any negative impact of cleaning solutions on the translucency and color consistency of retainers. Therefore, this study aimed to assess the effect of different cleaning solutions on the light transmission (translucency) rate of two distinct types of clear thermoplastic sheets. Materials and Methods: Two different clear thermoplastic sheets (Erkodent, Shodental), and five disinfectant solutions including chlorhexidine, Listerine, hydrogen peroxide, GUM whitening, and acid acetic served as the study materials and distilled water was used as control. The samples in each group (N=12) were immersed in the respective solutions for 15 minutes, twice a week and their light transmittance was measured using spectrophotometry after one and three months. Statistical analysis was conducted using two-way analysis of variance, with the significance level set at P |
