It is common to see bottle-fed infants cutting thelower anterior incisors at the ninth month. The infants may be inother respects normal. Rachitis affects the teeth of the first denti-tion mostly, but may influence the form and structure of the teeth ofthe second dentition. The teeth of the first dentition in rachitis areeasily broken and are unnaturally white. In many cases the anteriorincisors show an incurvation on the lower cutting edge, which is oftenmistaken for Hutchinsons deformity. The first teeth in rachitis areeasily eroded. It is not uncommon to see a rachitic infant with itswhole dental system in process of decay. The permanent teeth pre-sent abnormalities in inordinate size and longitudinal furrows. Syphilis.—The permanent teeth are affected by syphilis in a char-acteristic fashion. Fig. 96.
