 ‘Hutchinson's incisors’ and ‘Mulberry molars’ are dental developmental defects seen in children with congenital syphilis; they are rare conditions

 In Hutchinson's incisors, the incisal edge is either notched or screwdriver shaped. The bulbous crown is short and narrow (‘barrel shaped’). In the centre of the incisal edge a deep vertical central notch may be present (Figure 1.15a)

 Mulberry molars are characterized by multiple rounded rudimentary enamel cusps on the permanent first molars (Figure 1.15b)

 Hutchinson's incisors and mulberry molars are caused by direct invasion of tooth germs by Treponema organisms during tooth developmentFigure 1.15 (a) Hutchinson's incisors of congenital syphilis. Note screwdriver shape and central notch on the crowns of upper and lower permanent incisors. (b) Mulberry molars of congenital syphilis. Note multiple poorly formed globular cusps on the occlusal surfaces of mandibular permanent first molars.(source: images by kind permission of Professor Charles Dunlap, Kansas City, Kansas, USA.)
