title: Multiple dens invaginatus and cranio-vertebral abnormality.
abstract: This paper reports a case of multiple dens invaginatus (DI) bilaterally involving the maxillary central incisors, mandibular canines, and first premolars. The patient was a 11-year-old boy with steeple-head and mild mental retardation. The maxillary central incisors showed disproportionately large crowns and short roots. A roentgenographic survey of the skeletal system showed a sutural hyperostosis of the skull at bregma and a hypoplastic cervical vertebra. The review of the literature yields 6 cases of multiple DI, including the present case; these can be classified into 2 types, cases of only DI and cases of DI with anomalies of skeletal and other systems. Morphological differences in the central incisors are found between these 2 types.
