A patient has 'Hutchinson incisors' (notched upper incisors) and 'mulberry molars' (poorly formed first molars). What is the diagnosis?

Hutchinson incisors (centrally notched, screw-driver shaped upper central incisors) and Mulberry molars (first molars with multiple small rounded enamel nodules instead of cusps, resembling a mulberry) are pathognomonic of congenital syphilis caused by Treponema pallidum crossing the placenta. Together with interstitial keratitis and VIII nerve deafness, they form Hutchinson's triad. These are late manifestations appearing in deciduous/permanent dentitions.
