Impact of popular beverages on polyamides versus polymethyl methacrylate denture base materials colour stability: in vitro study

Abstract Background Changing of different denture base materials colours could have a detrimental impact on patients' satisfaction and make them seek more frequent adjustments to their prosthesis; hence this study was conducted investigate the colour stability conventional polymer (PMMA) polyamides. Methods Specimens PMMA thermoplastic polyamides were constructed according manufacturer instructions utilized during current study. For test total 80 specimens with dimensions 40 mm (length) X 20 (width) 0.8 (thicknesses), in divided into two equal groups ( n = 40) (PMMA specimens). Results When compared polymethyl methacrylate resin, polyamid resin exhibited greatest change P 0.001). 7 30 days, both had value tea solution. One-Way ANOVA < 0.00001). Conclusions Within limitation vitro study, we found that heat-cure has significant higher when Polyamides after immersion tea, cola, coffee distilled water solutions for days.
