I wish to report on a type of dystrophy of the 6 year molars which I have observed in a number of cases of congenital syphilis.
In cases of dystrophy of this sort the diameter of the crown is normal, and there is no deficiency of enamel or special tendency to early caries. The cusps, of normal size, are rolled inward without any shoulder at the crown and give the appearance of being clinched.
The impression for figure 1 was taken from the tooth of an under-developed girl aged 9 years who also showed Hutchinson teeth and a suggestive facies. The Hinton test was positive.
I have observed these changes only in cases of congenital syphilis, though it is probable, as is true of cases of the typical mulberry molar, that they may occasionally be found in cases of nonsyphilitic conditions due to some long illness occurring in the first
