Abstract

Purpose: This study investigated the effects of three indigenous food stains (tea, tobacco, turmeric) on a nanocomposite (Ceram-X-Mono, Dentsply DeTery, Konstanz, Germany), a microhybrid posterior (P60, 3M ESPE, St. Paul, MN, USA), and a universal microhybrid (Z100, 3M ESPE) resin-based composite (RBC). Materials and Methods: Thirty-six disk-shaped specimens were fabricated (10 ¥ 2 mm) for each type of RBC material, using a polytetraflouroethylene (PTFE) sheet. Specimens from each group were randomly distributed into three subgroups for each of the used stains.The baseline color values were measured using a spectrophotometer.The specimens were immersed in the staining solutions for a period of 3 hours per day for 15 days (3 hours/day ¥ 15 days). Following this, the color change value (DE) was calculated. Results and Conclusion: All the tested groups showed a clinically perceptible color change (DE values = 3.3 or >3.3), except for tea-stained P60 (DE = 3.15) and Z100 (DE = 1.63) groups.Turmeric caused the most significant color change for all the tested RBCs.The least amount of color change was observed with the Z100 (tea, DE = 1.63; tobacco, DE = 13.59; turmeric, DE = 38.77) group that was statistically significant from P60 (tea, DE = 3.15;tobacco, DE = 18.83;turmeric, DE = 57.72), and Ceram-X-Mono (tea, DE = 3.32; tobacco, DE = 18.83; turmeric, DE = 53.95) groups.
