Iatrogenic root perforations sometimes occur during root canal treatment or when preparing the root canal for a post. The inflammation in the periradicular tissues caused by root perforation reduces the prognosis of the involved tooth. The situation may be further complicated if by coronal leakage, microorganisms are allowed to infect the canal and the periradicular region. This clinical report presents a nonsurgical technique, based on the internal matrix concept, using both calcium hydroxide and SuperEBA together to repair root perforations. The author has experienced good clinical results with this perforation repair technique.
医源性根管侧穿有时发生在根管治疗期间或为桩核预备根管时。根管侧穿引起的根尖周组织炎症会降低患牙的预后。如果存在冠部渗漏，使微生物感染根管和根尖周区域，情况可能会更加复杂。本临床报告介绍了一种基于内部基质概念的非手术技术，联合使用氢氧化钙和SuperEBA修复根管侧穿。作者采用这种侧穿修复技术取得了良好的临床效果。
