摘　　要：目的探讨渗透树脂修复磨牙⁃切牙矿化不全的美学效果,为临床应用提供参考。方法筛选符合纳入标准的轻度磨牙⁃切牙矿化不全患者12例(36颗患牙),使用渗透树脂进行修复,于治疗前(T0)、1周复诊(T1)、6个月复诊(T2)时用Crystaleye比色仪拍摄照片,计算分析不同时刻病损区与周围正常釉质区的色差值ΔE;进行口内照相,使用Adobe PhotoshopCS3软件对不同时刻图像的病损面积和患牙唇面总面积进行计算,得出相应的病损面积比(R)及治疗有效率(SR),通过比较不同时刻色差值(ΔE)、R值的大小,判断渗透树脂治疗磨牙⁃切牙矿化不全的有效性,评估其美学效果。采用重复测量单因素方差分析对结果进行统计分析。结果轻度磨牙⁃切牙矿化不全患牙经渗透树脂治疗后色差值(ΔE)明显降低,病损面积比R值较治疗前明显缩小,差异有统计学意义(P<0.001),治疗有效率SR值可达86.02%,美学效果显著,且有利于保存天然牙体组织,符合微创医学的观点。结论渗透树脂修复轻度磨牙⁃切牙矿化不全患牙,美学效果良好,推荐临床使用。Objective To evaluate the clinical effects of resin infiltration in treating molar-incisor hypomineralization.Methods Twelve patients(36 teeth)with mild molar-incisor mineralization imperfecta who met the inclusion criteria were selected and treated with penetrating resin.Before treatment(TO),at the one-week follow-up(T1)and at the six-month follow-up(T2),a Crystaleye spectrophotometer was used to take photos,and the color differences(ΔE)between the lesion area and the surrounding normal enamel area at different times were calculated and analyzed.The area of the lesion and the total area of the labial surface of affected teeth were calculated using Adobe Photoshop CS3 software.The corresponding area ratio(R)and treatment efficiency(SR)were obtained.The R value was used to judge the effectiveness of resin penetration in the treatment of molar and incisor mineralization imperfecta and to evaluate its aesthetic effect.The results were analyzed by repeated measures one-way ANOVA.Results The color difference of the lesion area vs sound adjacent enamel(△E)decreased significantly,and that of the lesion area decreased significantly after resin infiltration(P<0.001).The success rate was approximately 86.02%,which means that the esthetic effect of resin infiltration in treating molar-incisor hypomineralization was remarkable.No important adverse events or side effects were observed.Conclusion The aesthetic effect of resin infiltration in the treatment of mild molar and incisor hypomineralization is good.This method is recommended for clinical use.
