Abstract

We histologically examined the effects on the periapical tissue of various dental filling materials applied as retrofillings in rats and compared them with those of amalgam. The 4-META-TBB resin Superbond and the light-cured composite resin produced the least severe inflammatory reaction, with the greatest amount of new bone. In these specimens, regeneration of a part of the periodontal ligament was also observed. These results indicate that these materials might be very biocompatible and thus foster the natural regeneration of the periapical tissue.

摘要

我们通过组织学方法研究了在大鼠中用作倒充填材料的各种牙科充填材料对根尖周组织的影响，并将其与汞合金的影响进行了比较。4-META-TBB树脂Superbond和光固化复合树脂产生的炎症反应最轻，新骨量最多。在这些标本中，还观察到部分牙周膜的再生。这些结果表明，这些材料可能具有非常好的生物相容性，从而促进根尖周组织的自然再生。
