The Effect of Nicotine Lozenge Over Teeth Bleaching During Cigarette’s Addiction Treatment

Abstract

The aim of this study was to evaluate the effect of nicotine lozenge on teeth staining with/without bleaching in animal model study. A total of 15 Wistar rats were exposed in an acrylic container to 10 cigarettes smoke three times a day for 8 minutes per time, and sacrificed after 60 days. A total of 30 incisor teeth were treated (n=10) as the following: Group-1: in-office bleaching, at-home bleaching and immersion in artificial saliva; group-2: in-office bleaching, at - home bleaching and immersion in nicotine lozenge solution and in artificial saliva; group-3: immersion in nicotine lozenge solution and in artificial. The specimens of all groups were photographed using a stereomicroscope at T1) immediately after the extraction and before any treatment; T2) after one month of the treatment; and T3) after two months of the treatment. Four equidistant points of each specimen were analyzed using CMYK shade guide. The data were analyzed one-way ANOVA test followed by Tukey test for multiple comparisons with (a ≤ 0.05). In group-1, there was a significant difference of the color saturation of specimens between T1 and T2, and between T1 and T3 readings (P<0.0001). In group-2, there was a significant difference of the color saturation of specimens between T1 and T2, between T2 and T3 readings (P<0.0001). In group-3, there was a significant difference of the color saturation of specimens between T1 and T2, and between T1 and T3 readings (P<0.0001). The usage of nicotine lozenge promotes teeth lighting with/without bleaching.
