Abstract:Objective To explore the effects of porcelain veneers and resin veneers on color stability in patients with mild to moderate dental ffuorosis. Methods A total of 86 patients with mild to moderate dental ffuorosis admitted to the Department of Prosthodontics, Huanghua Orthopedic Hospital from November 2023 to November 2024 were selected, and they were divided into group A and group B by the random number table method, with 43 patients in each group. Group A was treated with resin veneers, and group B was treated with porcelain veneers. The restoration color stability, restoration marginal adaptation, restoration surface integrity and restoration retention rate were compared between the two groups. Results The excellent and good rates of restoration color stability in group B at 6 and 12 months after restoration were higher than those in group A (P<0.05). The excellent and good rates of restoration marginal adaptation in group B at 6 and 12 months after restoration were higher than those in group A (P<0.05). The excellent and good rates of restoration surface integrity in group B at 6 and 12 months after restoration were higher than those in group A (P<0.05). At 12 months after restoration, the restoration retention rate of group B (97.66%) was higher than that of group A (91.38%) (P<0.05). Conclusion Compared with resin veneers, porcelain veneers have more ideal color stability, marginal adaptation, surface integrity and restoration retention rate in the restoration of mild to moderate dental ffuorosis, which is worthy of clinical application.
