白血病骨髓移植患者慢性根尖周炎患牙的保存治疗

Preservation of teeth with chronic periapical diseases in leukemia patients before bone marrow transplantation

目的:探讨白血病骨髓移植患者慢性根尖周炎患牙保存牙齿并行根管治疗的可行性与安全性。方法:15例白血病患者骨髓移植前15颗慢性根尖周炎患牙,X线片示根尖阴影,阴影直径小于0.5cm。掌握适当的时机,限定血象标准(白细胞不低于3.0×109/L,血小板>50×109/L),严格遵循根管治疗原则操作,并在骨髓移植后定期复查。结果:15例患者骨髓移植期间均未发生任何牙源性感染。15颗患牙的根尖病变均受到控制。结论:在一定条件下,骨髓移植患者根管治疗是安全的的、可行的,慢性根尖周炎患牙经过完善的根管治疗是可以保留的。

Objective：To evaluate the safety and feasibility of root canal therapy in leukemia patients before bone marrow transplantation.Methods：15 root canal therapy of teeth with chronic periapical diseases were performed in 15 patients with leukemia before bone marrow transplantation.Diameters of the shaded area of periapex were all less than 0.5 cm.The root canal therapy was done at appropriate time,restricted hemateikon（neutrophil counts range from 3.0×10^9/L -10×10^9/L,platelet counts more than 50×10^9/L）,all the teeth were done with root canal therapy according to the principle of root canal therapy.All the patients were monitored by return visit after transplantation.Results：It did not happen any odontogenous complication with 15 patients during the bone marrow transplantation period.The periapical diseases of 15 teeth have been well controlled after root canal therapy.Conclusion：Teeth with chronic periapical diseases of patients with leukemia before bone marrow transplantation can be preserved after adequate root canal therapy and the root canal therapy is safe.
