摘要：

The radiographic appearance of filling material extruded into periradicular tissues during obturation of root canals was studied over time. Recall radiographs for up to 61/2 yr were compared with immediate postoperative films. Consistently, less material was evident at successive postoperative periods. This study indicated that given time, the two zinc oxide and eugenol-based sealers studied will be removed from periradicular tissues. It also indicated that sealer is removed from periradicular tissues more rapidly than gutta-percha. © 1990 The American Association of Endodontists.
