[A rare case with hyperdontia in deciduous and hypodontia in the permanent dentition].

Abstract

Brief literature data are presented about the incidence of the anomalies in the number of teeth: decreased--hypodontia and increased--hyperdontia, and the possibilities of their manifestation in the deciduous and later in the permanent dentition. A rare case is described with hyperdontia in the deciduous but hypodontia in the permanent dentition, namely: supernumerary II and absent 5[25/5[5 in a boy aged 4 years and 7 months. No family loaded anamnesis has been established nor any deviations in the physical and neuro-psychic development of the child. The necessity of an early and accurate diagnosis in similar cases are stressed upon as well as their follow up care with a view to intentional orthodontic treatment for the best arrangement of the permanent dentition.
