The results from this study showed a variety of pulpal responses to various calcium hydroxide materials when placed directly on the dental pulp. Two of the materials proved to be more successful at stimulating reparative dentin bridging and healing of the underlying pulp tissue. The remainder of the pulp capping agents were ineffective at healing the pulp and forming a reparative dentin bridge. When teeth were capped with these other agents, the pulp showed necrosis and chronic inflammation.
这项研究的结果表明，当将各种氢氧化钙材料直接放置在牙髓上时，牙髓会产生多种反应。其中两种材料在刺激修复性牙本质桥接和下方牙髓组织愈合方面表现更为成功。其余的牙髓盖髓剂在牙髓愈合和形成修复性牙本质桥方面无效。当用这些其他制剂覆盖牙齿时，牙髓出现坏死和慢性炎症。
