Calcium hydroxide may induce apical root closure in affected mature teeth as well as in immature teeth. Once an apical hard tissue barrier is formed, a permanent root canal filling can be safely condensed. Two cases are described in which calcium hydroxide induced apical root closure in mature molar teeth where the apical constriction was lost because of chronic inflammatory process.
氢氧化钙可诱导患牙的成熟恒牙及未成熟恒牙根尖形成牙根闭合。一旦形成根尖硬组织屏障，就可以安全地进行永久性根管充填。本文描述了两例成熟磨牙因慢性炎症过程导致根尖缩窄消失后，氢氧化钙诱导根尖形成牙根闭合的病例。
