目的：评价 Resilon／Epiphany Self-Etch（RESE）在根管治疗术中的充填质量。方法：收集30颗因牙周病或正畸治疗需要拔除的离体下颌前磨牙，随机分为2组，牙胶／AH plus 组16颗牙，RESE 组14颗牙。经常规开髓拔髓、根管预备后，实验组以 RESE 充填根管，对照组以牙胶／AH plus 充填根管。根管充填完毕摄 X 线牙片计分评价2种材料根管充填的影像质量。结果：2种充填材料颊舌向 X 线评价均高于近中远中向（P ＜0．05），颊舌向 X 线观察2种充填材料没有差异（P ＞0．05）；近远中向 X 线观察 RESE 组根充的影像质量好于牙胶／AH plus 组（P ＜0．05）。结论：RESE 充填系统具有良好的 X 线阻射性，有利于通过 X 线片观察其根管充填效果。

Objective:To evaluate the quality of root filling with Resilon/Epiphany Self-Etch(RESE).Methods:30 recently extrac-ted mandibular premolars were randomly divided into 2 groups.After root canal preparation,the roots in experimental group(n =1 4) were filled with RESE,those in control group(n =1 6)were filled with Gutta-percha/AH plus.The quality of the optical obturation was evaluated by X-ray photography.Results:The buccolingual X-ray scores of the two filling materials were higher than the mesiodistal sores(P <0.05),there was no statistical significance between the two kinds of filling materials(P >0.05).The mesiodistal X-ray score of RESE group was higher than that of Gutta-percha/AH plus group(P <0.05).Conclusion:The X-ray resistance of the RESE filling system is more favorable than Gutta-percha/AH plus for the evaluation of root filling quality by X-ray examination.
