Regenerative endodontic treatment (RET) may not be suitable in some necrotic young permanent molars due to coexistent roots with closed and open apices, and/or inadequate apical bleeding in one or more roots. Here, we present a combined treatment approach utilising conventional root canal treatment in the closed-apex roots and RET on the open-apex roots of necrotic young molars. The closed-apex roots of 8 molars received root fillings, and their open-apex roots were treated with a regenerative endodontic procedure. In another molar, the failed RET on one root was retreated by conventional root canal filling, preserving other revitalised roots. After 4-6 years, all teeth showed periapical healing in the absence of clinical symptoms. The combined conventional and regenerative treatment approach can yield favourable healing outcomes in necrotic, young molar roots with different levels of apical closure. Likewise, failed revitalised roots can be retreated separately with conventional root filling.
由于存在根尖封闭和开放的共存牙根，和/或一个或多个牙根的根尖出血不足，再生性牙髓治疗（RET）可能不适用于某些坏死的年轻恒牙磨牙。在此，我们提出一种联合治疗方法，即在坏死年轻磨牙的根尖封闭牙根中采用传统根管治疗，在根尖开放牙根中采用RET。8颗磨牙的根尖封闭牙根进行了根管充填，其根尖开放牙根采用再生性牙髓治疗程序进行治疗。在另一颗磨牙中，一根牙根上失败的RET通过传统根管充填进行了再治疗，保留了其他恢复活力的牙根。4至6年后，所有牙齿均显示根尖周愈合且无临床症状。传统与再生联合治疗方法可使根尖封闭程度不同的坏死年轻磨牙牙根获得良好的愈合效果。同样，失败的恢复活力的牙根可以用传统根管充填分别进行再治疗。
