Discoloration of the teeth in patients with cystic fibrosis of the pancreas: Histologic studies☆

Abstract Detailed histologic studies of teeth obtained from thirty-two patients with cystic fibrosis of the pancreas were undertaken with regard to the presence, distribution, and nature of the peculiar discoloration of the teeth observed in such patients. A yellow discoloration in dentine was usually observed in ground sections of these teeth when viewed by tungsten incandescent light. Fluorescence microscopy of these sections revealed fluorescent patterns which appeared to parallel the yellowish patterns observed under tungsten light. No such abnormalities were discernible in decalcified sections studied under tungsten light.
