The effect of electronic cigarettes on color stability of different denture teeth.
Öz
Objectives: The aim of this in vitro study is to compare the coloration of different type of denture teeth with electronic cigarette smoke depend on thermal aging.
Methods: Denture teeth of three different materials were used: microfiller reinforced polyacrylic resin (Vitapan, VITA Zahnfabrik), nanofilled composite resin (Sr Phoneres II, Ivoclar Vivadent AG), and feldspathic ceramic (Lumin Vacuum; VITA Zahnfabrik). The specimens were then randomly separated into groups (n = 6), according to the material of the denture teeth, thermal aging and the nicotine level of the electronic cigarette liquid. The color differences were determined by using a VITA Easyshade spectrophotometer.
Results: In groups which thermal aging is not applied; the color change caused by the electronic cigarette creates a statistically significant difference between 3 different materials (p <0.05). ΔE * ab value of Lumin vacuum is significantly lower than SR Phonares II; however, there is no significant difference in ΔE00 value. There is a statistically significant difference between 3 different materials in terms of ΔE * ab and ΔE00 values in all groups undergoing thermal aging (p <0.05).
Conclusions: Denture teeth color was altered by ECIGs containing liquids with different nicotine contents.
