Effect of stimulating drinks on the mechanical properties of composite resin provisional restorative materials

Abstract

Aim: The objective of the study is to examine the effects of the consumption of caffeinated drinks common to the Saudi population regarding the mechanical properties of composite resin restorative provisional materials. Materials and methods: An in vitro approach has been utilized to analyze the flexural strength and microhardness of three different composite provisional restorative materials: Temphase™, Protemp™, and CAD Temp® monoColor, when immersed in three different caffeinated drinks: Arabic coffee, American black coffee, and cappuccino, distilled water was used as the control group for a duration of seven days (n = 10 for each test). Results were analyzed using two-way ANOVA and Tukey HSD tests. Results: All beverages significantly reduced the flexural strength of different composite provisional restorative materials investigated in the study. All beverages significantly reduced the microhardness of the Temphase™ material. Arabic coffee did not significantly affect the microhardness values of the Protemp™ material and did not have an impact on the microhardness of the CAD Temp® material. Conclusion: The surface microhardness and flexural strength of different composite resin materials were altered after emersion in different caffeinated drinks. Clinical significance: As excessive consumption of caffeinated beverages have a negative effect on the durability and longevity of the different composite resin provisional restorative materials, dentists should counsel patients with provisional restorations to reduce the detrimental effect associated with excessive consumption of these beverages.
