Clinical details of 192 teeth with preoperative periapical radiolucent areas, treated endodontically, are described. The presenting signs and symptoms as well as some postoperative observations are listed. Periapical radiolucent areas were most frequently found related to maxillary teeth: 55 percent were adjacent to teeth with a single root canal and 30 percent related to teeth with three root canals. Radiographic follow-up 1 or more years after therapy was possible in 125 of the root-filled teeth: of those teeth, 59 percent shows disappearance of the radiolucent area and 29 percent exhibited a decrease in size of the area. The degree of success did not appear to be related to the number of root canals filled per tooth but, rather, to whether or not the root filling was short of the radiographic apex. In addition, the prognosis made at the time of root filling was accurate in most cases when compared to the estimated success rates.
本文描述了192颗术前存在根尖周透射区且接受过根管治疗牙齿的临床细节。列出了其临床表现及术后的一些观察结果。根尖周透射区最常出现在上颌牙齿：55%与单根管牙齿相邻，30%与三根管牙齿相关。125颗根管充填后的牙齿在治疗1年或更长时间后可进行影像学随访：其中，59%的牙齿透射区消失，29%的牙齿透射区面积减小。成功程度似乎与每颗牙齿充填的根管数量无关，而是与根管充填是否未达影像学根尖有关。此外，与估计的成功率相比，大多数情况下根管充填时做出的预后是准确的。
