- Abstract
Objective: Evaluate the color and translucency of a nanoceramic resin subjected to hygiene practices and immersion in coffee over time. Materials and Methods: Specimens (n = 80, HT and LT, 0.5‐mm thick) of a nanoceramic resin were obtained and were divided in groups according to the simulated oral hygiene: no intervention (NT), brushing with an electric brush and water (BN), brushing with an electric brush and toothpaste for 10 s (BT), and immersion in mouthwash for 30 s (MW). Oral hygiene practices were repeated after staining in coffee solution for 15, 48, 336, 1440, 8640, and 35,040 min. Spectral wavelengths were recorded with a spectrophotometer at each time. ∆E00, ∆L′, ∆C′, ∆H′, and TP00 were calculated by CIEDE2000 and were evaluated by 2‐way ANOVA, repeated measures ANOVA, and Tukey's HSD test (α = 0.05). Results: ANOVA showed significance among factors for ΔE00 (p < 0.05), with higher ΔE00 for NT‐HT (11.7) and NT‐LT (11.2). After T6 (2‐year simulation), the lowest values were found for BT‐HT (5.3) and BT‐LT (4.9). All groups showed a reduction in lightness and translucency and increased chroma and hue. However, the smallest variations were found in the BT groups (p < 0.05). Conclusions: Brushing with toothpaste effectively minimized the color change of NCRs caused by coffee staining. Clinical Significance: Oral hygiene practices, such as brushing with toothpaste, might be important to minimize staining of nanoceramic resin restorations, especially in patients who frequently consume coffee.
