Fractured Central Incisor

I n c id e n t s ing the part in a hot saline solution. There was no improvement. After several visits, roentgenograms of the foot were taken, which proved negative as far as the bone structure was concerned. T he boy was then referred to a wellknown internist, who diagnosed the case as one of epiphysitis. The foot and leg were put in a cast, October 31, 1939, and this was worn for six weeks. During this time, sul­ fanilamide was administered. There was no change in the condition. T he patient walked only with the aid of crutches for the next ten weeks. He was referred to this office for a check­ up of his teeth, December 23. It should be noted here that there was no history of trauma nor was there any evidence of sys­ temic infection. It should also be noted that, for some time after the onset of the condition, the boy had been tested and treated for an allergy, with no results. A roentgenogram revealed an infected up­ per left first molar, which was immediately removed. Tw o days later, on Christmas Day, the boy’s mother reported that she had received the “ finest Christmas present ever,” that the patient had his shoes on and was running around “ like a regular boy.” She said further, “ He expects to attend classes in school on January 3.” L a te r the case was discussed w ith sev­ eral em inent pathologists an d internists, and it was agreed that, althou gh m ost unusual to say the least, the ch an ge was possible. In a n y case, the facts are these and th ey can be rea d ily substantiated b y all parties concerned. 88 Clinton Avenue.

The tooth was knocked loose by the blow and was fractured, as the x-ray film shows, but recovered from the blow and for fourteen years was normal. T he tooth was vital according to an electric pulp test. A t the time of extraction, a lingual pocket

A b o y , aged 6 years, the youngest in the fam ily and born late in the life of his parents, was brought to the office about three months ago for extraction of two very loose upper deciduous central incisors. After the extrac­ tion, the patient was dismissed with instruc­ tions for postoperative care. Recently, the mother brought the boy to the office because

of the appearance of two conical upper cen­ tral incisors, which had erupted after the first extraction. A roentgenogram taken im­ mediately showed that this was another set of deciduous central incisors. The second set was extracted under nitrous oxide anesthesia and it is hoped that the last, and this time permanent, set of upper central incisors will finally erupt.
