Ottolengui, M.D.S., D.D.S., LL.D., 80 West 40th St., New York. Electrolytic Therapeusis Versus Apicoectomy as an Efficient Method for Prevention and Eradication of Apical Infections. By DR. ARTHUR ZENTLER, New York City. Surgeon, Department of Oral Surgery, New York Throat, Nose and Lung Hospital (Columbia University, Advanced Course for Practitioners); Lecturer in Oral Surgery New York Post-Graduate Medical School and Hospital. At the invitation* of the Editor of DENTAL ITEMS OF INTEREST, I am submitting to the profession the beginning of a line of investigation, which I have carried on within the last two years for the purpose of arriving at the truth, as to: Ist. The need of electrolytic medication as a prevention for apical infections. *This invitation is the result of my remarks at the occasion of discussing a very interesting lantern lecture given recently by Dr. Ottolengui. It was a preliminary announcement of studies of the apical granuloma of the human body (not from lower animals), by himself and some collaborators at the suggestion of Dr. Berger. The substance of this preliminary announcement, as I understand it, is that some transformation brought on in the granulomatous area by electrolytic treatment, results in eradication of the infection. This (the eradication of infection) Dr. Ottolengui is satisfied to establish by the lack of radiolucency in the previously radiolucent area in the radiograph. It was and is my contention that the radiograph cannot be accepted as proof of eradication of apical infections and for this reason I have taken up the line of investigation described in the discussion of Dr. Ottolengui's lecture and in this article. These investigations were carried on by me without any knowledge of the work done by Dr. Ottolengui and his collaborators, or of Dr. Berger's suggestion to them. ME Dental Ttems of Interest 2nd. The reliability of electrolytic medication for eradicating apical infections. 3rd. The desirability of surgical treatment (apicoectomy, curettement, etc.) as a prevention for apical infections. 4th. The reliability of this later surgical procedure for eradicating apical infections. It seems logical to me that any therapeusis which would be successful in advanced cases of a certain lesion, would necessarily be successful in a less advanced lesion of the same type, and vice-versa, that if we are not able to cure a certain type of infection in its initial or less advanced phases with a certain method of treatment, that this therapeusis cannot be successfully applied in the more advanced forms of the same type of infection. I have therefore started my investigation with cases which from histories, oral examinations and radiographic interpretation, appeared to be cases of infected root canals, the infection extending to the apex and its surroundings, without however being cases of extensive bone destruction in the apical region. It was my intention to find out first whether electrolytic medication is successful in these cases, and if so found, to carry my investigation further in the field of more advanced apical infections. To establish next, in these cases where electrolytic medication failed, whether the surgical treatment (apicoectomy, curettement, etc.) would eradicate the infection. The fact that radiographic showings of diseased apical areas examined by men who have had more or less experience with entering surgically these parts, have proven to be insufficiently instructive as to the fact whether these parts were, or how extensively they were infected, prompted me to decide from the outset that I cannot rely upon the radiograph as a conclusive proof as to whether with one or the other method |
