Abstract
Root canals of dog premolar teeth were instrumented beyond the apices and enlarged up to the size of a No. 40 or 80 file and filled with calcium hydroxide up to the foramen. Ninety days later the histologic data showed more favorable results with the root canals instrumented until file No. 80.
摘要
对犬前磨牙的根管进行根尖外预备，扩大至40号或80号锉的尺寸，并在根尖孔处充填氢氧化钙。90天后，组织学数据显示，根管预备至80号锉时的效果更佳。
