Premature loss of deciduous teeth

Abstract

We have described a boy aged 4 years who exhibited premature shedding of deciduous teeth. At 3 years of age he had only seven deciduous teeth remaining. It was shown that there had been incomplete formation and some premature absorption of the roots. There was a genu valgum and doubtful radio-logical evidence of an osteodystrophy. The only abnormal biochemical finding was a low serum alkaline phosphatase level.
