**Core Concept**
Hutchinson triad refers to a classic clinical triad associated with congenital syphilis, comprising of interstitial keratitis, deafness, and Hutchinson teeth (notched incisors). This triad is a result of the infection of the fetus with Treponema pallidum during pregnancy, leading to various systemic manifestations.
**Why the Correct Answer is Right**
The Hutchinson triad is a well-documented manifestation of congenital syphilis. The notched incisors, or Hutchinson teeth, are a result of the premature loss of primary teeth, leading to malformation of the permanent incisors. This is due to the infection of the dental tissues by Treponema pallidum. Deafness and interstitial keratitis are also characteristic features of congenital syphilis, resulting from the infection of the auditory and ocular tissues.
