In spite of the incidence of recurrent caries and gingival inflammation surrounding the gingival margins of interproximal silver amalgam restorations, little information exists on the efficacy of finishing procedures in this location. This study was intended to evaluate surface smoothness of interproximal silver amalgams using four finishing techniques. Results indicated that surfaces finished using the carve, floss, and finishing strip polish consistently produced a measurably smoother surface (p less than 0.01) than did the other techniques. The use of finishing strips on the gingival margin of Class II silver amalgam restorations shows promise of improving interproximal surface smoothness.
尽管邻面银汞合金修复体龈缘周围复发性龋齿和牙龈炎症的发生率较高，但关于该部位修整程序效果的信息却很少。本研究旨在使用四种修整技术评估邻面银汞合金的表面光滑度。结果表明，与其他技术相比，使用雕刻、牙线和修整条抛光完成的表面始终能产生明显更光滑的表面（p小于0.01）。在II类银汞合金修复体的龈缘使用修整条有望改善邻面表面光滑度。
