ABSTRACT

Although the first case of supernumerary teeth had been documented almost 20 centuries ago, the etiology of supernumerary teeth still remains unclear. The prevalence of supernumerary teeth in the general Asian population is between 2.7% and 3.4%. The pathogenesis of supernumerary teeth has been attributed to phylogenetic reversion(atavism), splitting of the tooth bud(dichotomy theory), locally induced hyperactivity of the dental lamina and a combination of genetic and environmental factors(unified etiologic explanation). This report describes 3 cases of monozygotic twins with mesiodens who visited the pediatric dental clinic of Kyungpook national university hospital, and this is significant to support genetic factors involoved in the development of supernumerary teeth.
