Objective To analyze the effect of porcelain veneer restoration on aesthetic restoration effect and periodontal health in patients with dental fluorosis. Methods A total of 76 patients with dental fluorosis admitted to Hongru Dental Clinic in Xingqing District from June 2022 to October 2024 were selected and divided into the control group (n =38) and the observation group (n =38) by the random number table method. The control group was given all-ceramic crown restoration, and the observation group was given porcelain veneer restoration. The aesthetic restoration effect, periodontal health indexes, complications and patient satisfaction were compared between the two groups. Results The total effective rate of aesthetic restoration in the observation group (94.74%) was higher than that in the control group (73.68%) (P <0.05). After treatment, the PD, SBI, PIS and PLI in the observation group were all lower than those in the control group (P <0.05). The incidence of complications in the observation group (2.63%) was lower than that in the control group (21.05%) (P <0.05). The patient satisfaction rate in the observation group (92.11%) was higher than that in the control group (71.05%) (P <0.05). Conclusion Porcelain veneer restoration can effectively improve the aesthetic restoration effect of dental fluorosis, maintain periodontal health, enhance patient satisfaction, and reduce the incidence of complications.
