A dentist has just moved away from Burlington, who has been in practice there for fifteen years, and during that time he has been using arsenic for obtunding sensitive dentine, and he has succeeded in accomplishing his purpose admirably. I have found in one month half a dozen filled teeth containing dead pulps, and, of course as many alveolar abscesses in active operation. The evils arising from such abominable methods of practice are simply appalling. * * * * * I have less frequently met with cases where those fistulous openings were on the neck or chest. In those cases the roots of the teeth are usually long, and when the abscess breaks through the lower border of the jaw, and the pus comes in contact with the soft tissues, it follows the course of the muscles and forms a sinous as it gravitates to some point on the neck or chest. I have known of a number of such cases being under medical treatment for years, where the affection was supposed to be of a strumpous nature, and the real cause was not suspected, and in every case a rapid recovery has followed the extraction of the offending tooth. * * * * * Gentlemen, I have no doubt but the most of you are disappointed in the nature of this paper. I have scarcely alluded to the treatment and filling of pulpless teeth. That had not been my purpose. But I have wished to call attention to the fact that a large majority of the ailments above referred to have been due to diseased teeth that have never received any attention whatever at the hands of competent dentists. That pulpless teeth and roots may be treated, filled, and preserved in health in a majority of cases, is a settled question. Every well-informed dentist knows that to be a fact, the distinguished Dr. Sexton and the able editor of the _Medical Record_ to the contrary notwithstanding.--_Iowa State Med. Reporter._ ARTICLE III. DEAD TEETH IN THE JAWS. TRUMAN W. BROPHY, M. D., D. D. S. In reply to Dr. Sexton on this subject, Dr. Brophy makes these pertinent remarks in the journal of the American Medical Association: Dr. Sexton says: "The retention in the jaws of teeth which are diseased, have become irredeemably sensitive to thermal influences, or deprived of adequate periosteal nourishment through calcareous formations about the roots, very frequently gives rise to nervous diseases about the head. I am convinced that these reflected nerve influences manifest themselves much oftener since dentistry has come more extensively into practice during the present generation, and greater efforts are made to retain defective teeth in the jaw."
