• Objective To evaluate the color change stability and patient satisfaction after one‐year of at‐home bleaching with 10% carbamide peroxide (CP) in trays with or without reservoirs. Materials and methods Forty‐six patients were subjected to bleaching with CP (3 h/daily; 21 days) with a bleaching tray with or without reservoirs. The color was measured one‐month and one‐year after the completion of bleaching using the spectrophotometer (ΔEab, Δ00 and ΔWi), and shade guide units (ΔSGU). Patients' satisfaction were assessed using a 5‐point Likert Scale questionnaire. Data were submitted to paired t‐test (α = 0.05). Results No significant difference between color change after one‐month and one‐year was observed (VITA Classical shade guide unit and the ΔWi; p > 0.53). Significant differences were observed for the VITA Bleachedguide 3D‐MASTER shade guide, ΔEab and ΔE00 (p < 0.03). The level of patient satisfaction was similar between groups (p = 1.00). Conclusions Bleaching tray design did not have any influence on the bleaching stability for the 10% CP (Opalescence PF, Ultradent). Patients were very satisfied with the bleaching outcomes regardless of the bleaching tray design. Clinical relevance Placement of reservoirs in bleaching trays does not increase longevity of dental bleaching. No clinically important color rebound was observed 1 year after bleaching with 10% CP.
