Twenty-two pairs of bilateral primary canines, indicated for extraction due to excessive crowding, were chosen to study pulpal response to direct pulp capping with two calcium hydroxide medicaments (Life and Dycal). Following mechanical exposure of the pulp and direct pulp capping with calcium hydroxide, the teeth were extracted after either seven or sixty-three days to determine both the immediate and long-term pulpal response to the medicaments. The results indicate no statistical difference between the two materials in terms of biological response. Favorable results as to degree of pulpal inflammation and matrix formation indicate direct pulp capping using calcium hydroxide in primary teeth with no pulpal inflammation may be a viable procedure.
选取22对因严重牙列拥挤而需拔除的双侧乳尖牙，以研究两种氢氧化钙药物（Life和Dycal）直接盖髓后的牙髓反应。在牙髓机械暴露并用氢氧化钙直接盖髓后，分别于7天或63天后拔除牙齿，以确定药物对牙髓的即时和长期反应。结果表明，两种材料在生物学反应方面无统计学差异。关于牙髓炎症程度和基质形成的良好结果表明，在无牙髓炎症的乳磨牙中使用氢氧化钙进行直接盖髓可能是一种可行的方法。
