In primary molars with root perforations of endodontic origin, tooth extraction and space maintainer are recommended. Calcium-enriched mixture (CEM) cement is a new biomaterial demonstrating favorable sealability/biocompatibility. This report presents a novel treatment modality for cases of primary molar teeth with root perforations associated with a periodontal lesion due to extensive inflammatory root resorption, whereby CEM was used as a perforation repair/pulpotomy biomaterial. Three cases of primary molar root perforations due to inflammatory resorption were selected; all cases were associated with furcal lesions of endodontic origin. Pulp chambers were accessed/irrigated with NaOCl; the root canal orifices were filled with CEM and restored with stainless steel crowns. Clinical/radiographic examinations up to 17 months revealed that all teeth were functional and free of signs/symptoms of infection and all had complete bone healing. Further trials are suggested to confirm CEM use for management of root perforations in primary molars exhibiting root perforation.
对于因牙髓源性导致牙根穿孔的乳磨牙，建议拔牙并使用间隙保持器。富钙混合物（CEM）水泥是一种新型生物材料，具有良好的密封性/生物相容性。本报告介绍了一种针对因广泛炎症性牙根吸收导致牙周病变且伴有牙根穿孔的乳磨牙病例的新型治疗方法，即使用CEM作为穿孔修复/牙髓切断术生物材料。选择了3例因炎症性吸收导致的乳磨牙牙根穿孔病例；所有病例均伴有牙髓源性的根分叉病变。用次氯酸钠进入/冲洗髓腔；根管口用CEM填充并用不锈钢冠修复。长达17个月的临床/影像学检查显示，所有牙齿功能正常，无感染迹象/症状，且均有完全的骨愈合。建议进一步试验以确认CEM在治疗出现牙根穿孔的乳磨牙牙根穿孔中的应用。
