Supernumerary primary teeth ; Succedaneous supernumerary tooth ; Dental lamina hyperactivity theory
Most supernumerary primary teeth erupt in the primary lateral incisor region and are reported to occur in 0.03 to 1.9% in the primary dentition. Most parents fail to recognize them because of their normal shape, eruption and exfoliation. Several theories have been proposed for the etiology of hyperdontia and the dental lamina hyperactivity theory is most widely accepted. When a supernumerary primary tooth develops, it is reported that there also exists a supplemental or rudimentary form of a succedaneous supernumerary tooth. Supernumerary primary teeth do not need specific treatment as 75% of them erupt and exfoliate normally Only periodic radiographic exams are necessary to find out whether there is any problem with the eruption of the succedaneous tooth. In the following two cases, a supplemental supernumerary primary tooth with a loss of the anterior developmental space was observed at the maxillary lateral incisor region. Radiographic examination revealed an impacted succedaneous supernumerary tooth at the palatal side of the supernumerary primary tooth.
