AM ERICAN PUBLIC H EALTH ASSO CIATIO N The American Public Health Association, oldest and strongest organization of its kind on the continent, w ill hold its sixty-first an nual meeting in Washington, October 24-27. The scientific programs are planned to inter est health officers, nurses, food and nutrition experts, sanitary engineers, school physicians, directors of hospitals, laboratories and clinics, child and industrial hygienists, and specialists in all branches of public health. Additional information may be obtained from the office of the American Public Health Association, 450 Seventh Ave., N ew York City. F. D. I.: C o m p e t i t i o n i n ' R o o t C a n a l W o r k Method for Verification of Root Canal Treatment For verification of a given procedure for root canal treatment, at least two dogs, aged 1-2 years, should be employed for histologicbacteriologic experiment. It is suggested that the lower cuspid, first molar and third molar on each side be treated. On one side, the treatment should be carried out on the teeth in the natural state. On the other side, the pulp should be extirpated and the root canal infected with a strain of Streptococcus v ir idans previously isolated from infected human teeth and known to be virulent for dogs. T he bacteriologist, who w ill make the definitive tests, must furnish the examined strain and be present when the culture is introduced into the dog’s teeth and must mark the dog for later identification. In addition to the teeth mentioned the upper cuspids should be infected similarly. The teeth should be sealed with an appropriate filling. Roentgenograms should be made at varying intervals. Evidence of periapical lesions indicates the time to commence root canal treatment (not under three months). The tw o upper infected incisors should not be treated, remaining a potential focus of systemic infection. One and one-half years after the completion of root canal treatment, roentgenograms should be made and the animals should be killed. From the animal, the lower first and third molars on both sides should be procured for histologic examination, while, from the lower cuspids cultures should be obtained for bacteriologic study. From the second animal, the lower cuspids should be taken for histo logic examination, w hile the lower first and
Announcements third molars on both sides should be examined bacteriologically. T he materials for investi gation should consist of all the teeth men tioned above (upper cuspids) together with their surrounding tissues, and the lower cus pids and first and third molars. Similarly, the upper cuspid and first molar should be obtained from each side, from one for bac tériologie, from the other side for histologic control. For the bacteriologic examination, it is suggested that the apices of the teeth be amputated with a rigidly aseptic technic, and pulverized, and the m aterial used for cultures. T he tissues around the apex should be scraped and this m aterial also used for cultural pur poses, in accordance with a procedure de scribed by Rosenow. T he bacteriologic exam ination must be carried out by the head of the department of bacteriology of the uni versity or institute nearest the place at which the work is to be done. T he m aterial may be
357
prepared for histologic examination in any laboratory having adequate facilities. Only serial sections can be presented for control. T he m aterial to be examined histologically must consist of the root apex with its sur rounding soft and hard tissues. T he detailed description of the method of treatment, the serial section and the results of the bacteriologic examinations must be in the hands of the president of the scientific commission of the F. D. I. not later than Aug. 1, 1935. In the meantime, on recommen dation of the scientific commission, the execu tive council of the F. D. I. w ill designate the members of the committee which is to make the aw ard. T o this committee will be re served the right of controlling the contest in any way they see fit. They will be particu larly concerned with the practicability of the proposed methods. The aw ard will be made as soon as the committee has finished its work.
