摘要
目的观察渗透树脂联合冷光美白治疗氟牙症患牙着色的效果。方法将18颗患有氟牙症的上颌离体前牙用牙龈保护剂沿牙长轴分隔为等大的近远中两部分,随机分为A、B区,A区进行冷光美白(冷光美白组)治疗,B区进行冷光美白联合渗透树脂(冷光美白+渗透树脂组)治疗,测定治疗前后的色阶和色度差异(用ΔE表示)。之后,随机选择其中6个样本,对表面微结构进行扫描电镜观察;另外选择6个样本用茶叶进行染色后,测定染色后的色阶和ΔE。结果治疗后,冷光美白组、冷光美白+渗透树脂组较治疗前色阶提高,差异均有统计学意义(P<0.05),ΔE分别为13.75、14.98;治疗后,冷光美白+渗透树脂组与冷光美白组色阶提高的差异无统计学意义(P>0.05);2组ΔE(t=-3.58,P<0.05)差异有统计学意义。扫描电镜观察可见冷光美白+渗透树脂组处理后釉质表面形态完整,釉质突间隙被充填;冷光美白组牙釉质突表面塌陷,较粗糙不平整,釉质突羽毛球拍形状不明显。再染色后2组色阶均降低,差异均有统计学意义(P<0.05),ΔE分别为19.69、18.95;冷光美白+渗透树脂组与冷光美白组色阶降低(t=-1.00,P>0.05)、ΔE(t=0.02,P>0.05)的差异均无统计学意义。结论冷光美白联合渗透树脂治疗氟牙症患牙着色的效果优于单纯冷光美白治疗。
Objective To observe the effect of infiltration resin combined with cold light whitening in the treatment of dental fluorosis.Methods According to the distance between teeth and the long axis of each tooth,18 anterior teeth were divided equally and randomly between group A and B.Samples in group A underwent cold light whitening,while samples in group B were treated with infiltration resin combined with cold light whitening.The color was measured before and after the treatment.Then,6 teeth(the first subgroup)were randomly selected from the 18 anterior teeth after measurement for scanning electron microscopy(SEM)to observe the surface microstructure of the teeth.Then,another 6 teeth(the second subgroup)were selected from the remaining 12 teeth for the measurement of the color level andΔE after being dyed with tea.Results After treatment,the color level changed significantly in group A and B(P<0.05),ΔE in group A and B was 13.75,14.98.There was no significant difference in the color level change between group B and group A,there was a significant difference in theΔE between the two groups(t=-3.58,P<0.05).SEM showed that the enamel surface was intact and that the enamel space was filled in group B.In group A,the enamel surface was reduced and uneven,and the characteristic badminton racquet shape of the enamel was not obvious.The color level was lower in both groups after staining,and these differences were significant(P<0.05),ΔE in group A and B was 19.69,18.95.There was no significant difference in the color level(t=1.00,P>0.05)andΔE(t=0.02,P>0.05)between two groups.Conclusion Cold light whitening combined with infiltration resin is better for treating dental fluorosis than cold light whitening alone.
