[Historical data on tooth changes presumed to be of syphilitic origin]

The Carabelli's-tubercle have been deemed by the Hungarian researcher K. Pándy of luetic origin. The supposition of Pándy has proved to be entirely erroneous. In the course of researches concerning the tooth changes described by Hutchinson and other dystrophic changes--the so called tooth stigmas--it has been ascertained that they were originated by the operational disorders of the internal secretion glands and by metabolism troubles, respectively, independent of luetic illnesses.
