In the fourth case, the radiographic finding, indicated apical ex-cision, thus finally substantiating the conclusions based on a knowledge ofsymptoms. In the light of this unusual but instructive experience I wouldinsist that the operator should always make a radiographic examinationbefore operating to excise a root end.
