The Effect of a Microencapsulated Iron Supplement, Hydrogen Peroxide Superior and Professional Dental Prophylaxis on the Color and Whiteness of Teeth

Purpose: To investigate the effect of a microencapsulated liposomal nano-iron supplement, an Fe+2 supplement, black tea, a bleaching agent with a new composition and professional dental prophylaxis (PDP) on tooth color and whiteness change. Materials and Methods: 84 extracted teeth were immersed in liposomal iron, Fe+2 and black tea solutions by special apparatus. Then different applications were applied: (1) no treatment, (2) water polishing, (3) PDP, (4) bleaching with 25% hydrogen peroxide superior (HPS). Measurements were taken at baseline, 2nd, 4th, 8th week and after applications. Statistical analysis of color and whiteness changes was performed by ANOVA and Bonferroni tests (α=0.05). Results: The effects of time, application, beverage and their interactions on color and whiteness were statistically significant (p
