冷光美白处理在牙齿美白中的效果

目的 分析对牙齿美白患者采用冷光美白的效果。方法 选取2022年1月-2023年12月于宝鸡市口腔医 院行牙齿美白治疗的70例患者作为研究对象，根据随机数字表法将患者分为对照组和观察组，每组35例。 对照组采用漂白处理，观察组采用冷光美白处理，比较两组牙齿美白效果、不良反应发生率、Vita 比色值、牙釉质损伤情况及治疗满意度。结果 观察组牙齿美白总有效率为97.14%，高于对照组的 80.00%（P ＜0.05）；观察组不良反应发生率为2.86%，低于对照组的20.00%（P ＜0.05）；观察组 治疗后Vita比色值低于对照组（P ＜0.05）；观察组牙釉质损伤发生率为2.86%，低于对照组的20.00% （P＜0.05）；观察组总满意率高于对照组（P＜0.05）。结论 相比于漂白美白方式，冷光美白方式不仅能够 起到提升牙齿美白效果，降低不良反应发生率及牙釉质损伤率，还能提升患者满意度，值得临床应用。

Effect of Cold Light Whitening Treatment in Tooth Whitening

Objective To analyze the effect of cold light whitening in patients with tooth whitening. Methods A total of 70 patients who underwent tooth whitening treatment in Baoji Stomatological Hospital from January 2022 to December 2023 were selected as the study subjects. According to the random number table method, the patients were divided into control group and observation group, with 35 patients in each group. The control group was treated with bleaching treatment, and the observation group was treated with cold light whitening treatment. The tooth whitening effect, incidence of adverse reactions, Vita colorimetric value, enamel damage and treatment satisfaction were compared between the two groups. Results The total effective rate of tooth whitening in the observation group was 97.14%, which was higher than 80.00% in the control group (P <0.05). The incidence of adverse reactions in the observation group was 2.86%, which was lower than 20.00% in the control group (P <0.05). After treatment, the Vita colorimetric value of the observation group was lower than that of the control group (P <0.05). The incidence of enamel injury in the observation group was 2.86%, which was lower than 20.00% in the control group (P <0.05). The total satisfaction rate of the observation group was higher than that of the control group (P <0.05). Conclusion Compared with bleaching whitening method, cold light whitening method can not only improve the whitening effect of teeth, reduce the incidence of adverse reactions and enamel damage rate, but also improve patient satisfaction, which is worthy of clinical application.
