    "ocrText": "Caso V. - Miss Grace Fryer, employed four and one holf years ago,\nhad a left lowor molar extratted one year ago. The wound apparently healed\nnormally. Six months later a sinus appeared at the eite of the extracted molar\nand Grained pue profusely for some months. X-raya taken at the Reconstruction\nHospital, New York City, on March 3,1924, showed evidence of a chronic infectious\nprocess in the jaw in the region of the extracted tooth. This patient left the\nhospital fivo days Inter unrelieved and with a diamosis of chronic osteomyolitis\no & the jaw, possibly due to phosphoros poisoning. She is, however, now reported\nby Dr. NeCaffrey, Dr. Harry Dunning's assistanet, to have recovered saticfactorily.\n(Dr. Herry Dunning 33 Tast 68th Street, Now York City.)\nIn addition to these five cases, we have the opinion of Dr. w.F. Tarry\nof Newark, a competent dental in remad to the condition of the jarro of\nsevoral other prosent or former employees of the Radium Cor oration. In De-Berry's\nopinion, Hães Kathorine Schaub, employed from March 22,1917, to Merch 19,1920,\nNães J. M. Smith, employed for geven years, Mies 0. Smith, and Hies Vern Eldridge\nall show jaw chanzes similar to those shown by Rudolph when he firet saw her.\nDr. Parry refuges to pull a tooth from any one of these girls, bolieving that\nif he does so an intractable necrosie, which he compares to that of phosphorus\npolsoning, will be initiated.\nCompotent dentnl surgoons in noston, who have examined the filma upon which\nDr. Barry bases hia opinion, with him, and state that, in their opinions\nMies Schaub is the only patient who shows definite hone changos.\nOne of your employees reports that a Madlingor (formerly lise\nNettie tozier), employed by the Radium Corporation for five years and up to three\nmonths ago, hnd a tooth extracted two months ago and that pus 1s still draining\nfrom the cavity.\nHoro, then, is a series of five enses of necrosis of the jaw - necrosis\nnot al all like the ordinary infections of the jam which do occasionally follow\nthe extraction of a tooth. Inatend of a localized process which hoals either of\nitself or after the establiement of drainazo, we havo a chronic progressive\nrotting away of the bone, which, in the opinion of Dr. Barry and of dental surgonns\nwhom we have consulted in Boston, is essentially different from an ordinary infec-\ntious process or from tuberculoeis of the bone, but resembles practically exactly\nthe necrosis of the jaw remulting from phosphorus poisoning. In our opinion, 50\ngroat an incidance enong your employees of this unusual disease procese in the\njam cannot be coincidence but must be dependent upon some typo of bone damage\noccasioned by the employment.\nANALYSIS OF POSSIBLE TOXIO AGRNTS.\nIn view of the excellent goneral hyrãone of the work as conducted in\nyour factory, it seems at once advisable to atudy the special ingredients used\nin the luminous material.\nThe base, \"Undark\", of the luminous paint contains no phosphorus but\nconsiste of a luminous zine sulphide containing minute traces of coppar combined\nwith small amounts of rndinm bromide, probably changed later into Tadium sulphate.\nThe amount of radium bromide per gram of dry luminoum powder bese averages,\naccording to Mr. Viedt, 0.007 mg. intimately mixed with the sine sulphide. The\nvehicle is varied and the peint is applied with fine brushes.\nAs wo learned from the dial painters that until six months amp it was"
