Metapex糊剂在根尖诱导成形术中的应用

Clinical observation of Metapex in apexification

目的：观察Metapex糊剂在大龄患者根尖诱导成形术中的效果。方法：14名患者14颗牙,平均年龄22.8岁,根尖周均有暗影,牙根未发育完成。术后每3个月复查1次,连续观察1～2年。结果：从封Metapex糊剂至永久充填的平均时间为7.1个月;在永久充填前均未更换Metapex糊剂;根尖闭合形式类型为Ⅱ型或Ⅲ型。结论：Metapex糊剂是一种良好的根尖诱导成形剂,患者的年龄及根尖周炎症不影响治疗效果,治疗过程中无需换药,药物与根尖周组织紧密接触可避免Ⅳ型闭合。

Objective： To observe the efficacy of Metapex in the apexification of older patients. Methods： This study involved 14 patients, between the ages of 15 and 52 years old, the average age was 22.8 years. Every one of the 14 teeth had a radiolueent apex. The patients underwent a clinical and radiological cheek-up every 3 months. The period lasted for 1-2 years. Results： From Metapex sealing to permanent filling, the average time of the 14 teeth was 7.1 months. All the patients didn＇t change the medicament during the treatment. All the apexes developed as typeⅢ or type Ⅳ. Conclusion： Metapex paste is an excellent medicament for apexification. The patient＇s age and preoperative radiolucency had no influence on the outcome. It was unnecessary to change the medicament before permanent filling. Paste connected the soft tissue could avoid forming type Ⅳ apical closure.
