超声大块树脂充填深龋Ⅱ类洞的临床观察

Clinical evaluation of Sonic Fill resin ultrasonic filling system in the permanent teeth of class Ⅱ molar caries

目的比较超声大块树脂和琥珀纳米树脂在磨牙深龋Ⅱ类洞的临床应用效果。方法选取86位患儿的156颗龋坏的年轻恒磨牙,随机分为两组。A组:Sonic Fill超声树脂充填;B组:琥珀纳米树脂充填,记录操作时间。术后6个月、1年及2年复查,检查充填体密合固位,继发龋及牙髓情况。结果 A组患者充填6个月、1年和2年后成功率分别为98.7%,97.4%和95.8%,与B组比较无显著差异(P>0.05)。A组患者平均操作时间为16分钟,与B组比较差异有显著性(P<0.05)。结论超声大块树脂对于深龋Ⅱ类洞充填修复效果优良,值得在年轻小患者中推广应用。

Objective To observe the clinical evaluation of SonicFill resin ultrasonic filling system in the permanent teeth of class Ⅱ molar caries. Methods 156 molars caries of 86 patients were randomly divided into two groups. Group A patients were flled with SonicFill ultrasonic flling system, group B patients were flled with Herculite precis .Patients were followed up after 0.5 ,1 and 2 years to check the situation of the flling and dental pulp, patient satisfaction and operation time.Results 0.5,1 and 2 years after treatment, the success rate of group A was 98.7%,97.4% and 95.8% respectively, there was no signifcant difference compared with group A and groupB （P〉0.05）. Conclusion SonicFill resin ultrasonic filling system can obtain better effect in the treatment of the permanent teeth of class Ⅱ molar caries, clinical treatment effect is satisfactory, it is worth clinical promotion.
