本文比较固化复合树脂和银汞合金充填治疗了下颌第一磨牙颊合面联合龋的效果。采用单盲自身对照的设计方法，用光固化复合树脂和银汞合金治疗50名患者100颗下颌第一磨牙颊合面联合龋。结果实验组疗效优于对照组(P<0.05)。证实用光固化复合树脂充填治疗下颌第一磨牙颊合面联合龋可以明显提高修复后的临床效果。
This article compares the effect of curing composite resin and amalgam filling for the combined cariousness of the buccal surface of the first mandibular molar. A single-blind self-control design method was used to treat 100 patients with 100 patients with first molars in 50 patients with combined carious buccal surface using light-cured composite resin and amalgam. Results The experimental group was better than the control group (P <0.05). Confirmed that the use of light-cured composite resin filling the mandibular first molar buccal co-caries can significantly improve the clinical effect after repair.
