Aim: The purpose of the present study was to compare the effectiveness of whitening toothpaste in reducing extrinsic stain with conventional fluoride paste. Materials and Methods: Total of 33 patients with visible extrinsic dental stains were surveyed. Participants were divided into 3 groups according to different toothpastes used. Lobene Stain Index was measured at baseline, after 2 and 4 weeks. Results: The results at baseline during week 2 showed reduction in stain area in all groups, but the difference was not significant. When comparing the stain level changes after 4 weeks, it was evident that Elgydium Whitening group showed the greatest reduction in stain area; it was significant. (p = 0.005) and stain intensity (p = 0.03) Moreover, this paste exhibited significant reduction of stain intensity (p = 0.03). Changes in stain intensity and area throughout a four- week period were insignificant for Colgate Total Advanced whitening and Colgate Total toothpastes (p > 0.05).The evaluation of the questionnaire data revealed no significant difference in stain intensity or area between smokers and non-smokers (p>0.05).There were also no significant differences between subjects consuming tea/coffee every day and ones who do not (p > 0.05).
