我们从组织学上研究了各种牙科填充材料作为后充填材料对大鼠根尖周组织的影响，并与银汞合金进行了比较。4-META-TBB树脂Superbond和光固化复合树脂产生的炎症反应最轻，新骨量最大。在这些标本中，还观察到牙周膜的一部分再生。这些结果表明，这些材料可能是非常生物相容的，从而促进根尖周组织的自然再生。
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.
