It is such faulty reasoning that I may say it is lack of reasoningto point to a well-filled canal at the end of which is a large abscess cavity,and say, This canal filling has failed. It is useless to fill canals as thisone is filled. Of course, the abscess cavity may have existed for yearsbefore the canal filling was placed in the tooth, but the universal tendencyis to assume that it did not, but that it developed after the canal fillingwas inserted. It should also be remembered that there is something more to thetreatment of pulp canals than the mere
