ABSTRACT
In patients with complete denture, some clinicians have used modelling plastic impression compound [MPIC] along tissue conditioner [TC] materials simultaneously. Little information is available on the composition of these materials and the interaction between them. The purpose of this study was to evaluate the influence of two components of MPIC on the structure and chemical composition of TC. In this experimental study, MPIC specimens were provided in 25x2 mm discs. Specimens were randomly divided into three groups and were immersed in ethanol 70%, plasticizer [dibutyl phthalate] and a mixture of them [ethanol 70% and dibutyl phthalate]. All of the discs were weighed with a digital balance before and 2, 4, 6 and 24 hours after immersion. Values were analyzed by non parametric Kruskal-Wallis [alpha= 0.05] and SPSS 16 for Windows [SPSS Inc., Chicago, IL] was used for statistical analysis. Statistical analysis indicated significant differences among all groups [p>.05]. Dibutyl phthalate [DBP] had high impact on the solubility of MP, while the mixture of dibutyl phthalate [DBP] and ethanol demonstrated the highest impact
