Abstract
Introduction: The most common electronic nicotine delivery system is electronic cigarettes. Most of electronic cigarettes consist of a battery and electric heater used to aerosolize a liquid to produce vapor which the user inhales. Poly methyl methacrylate comes in contact with a variety of foods and beverages altering its physical structure and appearance. Objectives: This study aimed to investigate the effects of electronic cigarettes smoking on color stability of CAD/CAM acrylic resin. Material and methods: This study was in vitro study in which sixty specimens of CAD/CAM acrylic resin was exposed to aerosols which were flavored and non-flavored with nicotine content (0 mg, 6 mg and 12 mg). A portable suction machine was modified to simulate smoking in vivo. Each specimen was exposed to 20 cycles of aerosol emitted by a single ECIG device. Color measurement was performed on the specimens before and after exposure to ECIG aerosol using a calibrated spectrophotometer. Results: No significant difference in color change found between groups exposed to flavorless e-liquid, while a significant difference found between flavored 0 mg. nicotine and 12 mg. nicotine groups (P = 0.002).Also, a significant difference found between flavored 6 mg. nicotine and 12 mg. nicotine groups (P = 0.002). According to Two Way ANOVA, flavor and nicotine contents have a significant effect on color change (P
