摘　　要：目的评价皓齿微研磨结合两种皓齿美白药物对于氟斑牙着色斑的治疗效果。方法选取20名氟斑牙患者,随机分为A、B两组(n=10),A组纳入148颗着色氟斑牙,B组纳入146颗牙齿,纳入的牙齿根据着色深浅参照CMYK比色数值将患牙分为轻度、中度和重度着色三个等级。A组使用皓齿微研磨+Opalescence Boost诊室美白一次,B组使用皓齿微研磨+Opalescence家庭美白一疗程,分别评估其美白效果,术后即刻及术后1周时的牙齿敏感程度、敏感持续时间以及患者对治疗效果的满意度。结果治疗后,A、B两组的总有效率分别为88.5%和95.2%,二者之间有显著统计学差异(P=0.026<0.05)。美白后即刻,A组无敏感1例,轻度敏感2例,中度敏感2例,重度敏感5例;B组无敏感3例,轻度敏感6例、中度敏感1例;两组敏感度之间有统计学差异(P=0.037<0.05)。美白后1周A组8例无敏感,2例轻度敏感;B组7例无敏感,3例轻度敏感;两组敏感度之间无显著差异(P=0.500>0.05)。A组平均敏感时间为(3.80±2.440)d,B组为(4.60±3.718)d,两组之间无统计学差异(P=0.576>0.05)。A组患者的治疗满意度为3.00±0.816,B组为3.40±0.516,两者之间无统计学差异(P=0.207>0.05)。结论综合考虑两种方法的优缺点,推荐采用微研磨+家庭美白治疗氟斑牙着色斑。Objective To evaluate the therapeutic effects of two methods for the treatment of stains caused by dental fluorosis.Methods Twenty patients with dental fluorosis were selected and randomly divided into two groups.Ten patients in group A included 148 teeth,and 10 patients in group B included 146 teeth.The included teeth were classified as light,moderate or severe according to the CMYK colorimetric value.Teeth in group A used Opalustre microgrinding combined with Opalescence Boost clinic whitening,and teeth in group B used Opalustre microgrinding combined with Opalescence family whitening.Their whitening effects,the sensitivity,the sensitive duration and the patients'satisfaction level immediately and one week after the surgery were evaluated.Results After treatment,the total effective rate of group A was 88.5%,and that of group B was 95.2%,with significant statistical difference(P=0.026<0.05).Immediately after surgery,1 case in group A was not sensitive,2 cases were mildly sensitive,2 cases were moderately sensitive,and 5 were severely sensitive.In group B,3 cases had no sensitivity,6 cases were mildly sensitive,and 1 case was moderately sensitive.There was a statistical difference between the two groups(P=0.037<0.05).One week after treatment,8 patients in group A were nonsensitive,2 patients were slightly sensitive.7 patients in group B were non-sensitive,and 3 patients were slightly sensitive.There was no statistical difference between the two groups(P=0.500>0.05).The average sensitivity time of group A was 3.80±2.440 days,and that of group B was 4.60±3.718 days.There was no statistical difference between the two groups(P=0.576>0.05).The average satisfaction of group A was 3.00±0.816,and that of group B was 3.40±0.516 with no significant difference between the two(P=0.207>0.05).Conclusion Considering the advantages and disadvantages of the two methods,it is recommended to use microgrinding and family whitening to treat stains of dental fluorosis.
