Clinical effect study of Beyond cold light whitening comprehensive therapy in treatment of dental fluorosis

目的观察并评估Beyond冷光美白综合疗法对氟斑牙的长期临床效果及安全性。方法 90例轻、中度氟斑牙分别采用Beyond冷光美白治疗(A组,30例)、Beyond冷光美白综合疗法(B组,Beyond冷光美白治疗和TREE家庭漂白联合应用治疗,30例)和Beyond冷光美白后加一次维护治疗(C组,30例),观察各组治疗结束时、治疗1,2,3年后的效果及牙齿敏感情况。结果 3组美白治疗后均有良好效果,且B组与C组有效率均高于A组。2年后A组与B组、C组以及3年后A组与B组、C组组间有效率比较差异均有统计学意义(P<0.05),B组与C组在治疗1、2、3年后比较差异均无统计学意义(P>0.05)。3组敏感症状均在第1次冷光美白后1 d内消失,组间比较差异均无统计学意义(P>0.05),B组与C组处理后牙齿未再出现任何敏感症状。结论两种Beyond冷光美白综合疗法在轻、中度氟斑牙的美白治疗中均收到很好的远期效果,且敏感反应较小,有很好的应用前景。

Objective To observe and evaluate the long-term clinical effects and safety of two comprehensive therapies of Beyond cold light whitening in the treatment of dental fluorosis. Methods Ninety patients with mild and moderate dental fluorosis were divided into three groups.Group A （30 patients） was given Beyond cold light whitening comprehen-sive therapy,group B （30 patients） was given Beyond cold light whitening combined with TREE family bleaching thera-py,and group C （30 patients） was given Beyond cold light whitening plus maintenance treatment for one time.The effects and tooth sensitivity situation of each group after the treatment and 1,2 and 3 years after the treatment were observed. Results All the 3 groups obtained good efficacy after the whitening treatment,and group B and group C were both high-er than group A in the effective rate.Pairwise comparison showed that there existed significant difference between group A and group B and between group A and group C 2 years after the treatment and also between group A and group B and between group A and group C 3 years after the treatment （P〈0.05）,but there existed no statistically significant dif-ference between group B and group C 1,2 and 3 years after the treatment （P〉0.05）.The sensitivity symptoms disap-peared within 1 day after the first cold light whitening treament in all 3 groups,with no significant between-group dif-ference （P〉0.05）.Not any sensitivity symptom occurred in group B or group C after the treatment. Conclusion Both comprehensive therapies of Beyond cold light whitening achieve good long-term effects and cause small sensitive reac-tions in the whitening treatment of mild and moderate dental fluorosis,which are of good application prospects.
