Multiple and relapsing supernumerary teeth associated to dens invaginatus. Review of the literature and case report.

: The aim of this paper is to show problems related to supernumerary teeth therapy according to their formation and mineralization. The clinical case of an 11-year old boy suffering from alteration of the eruptive sequence of the upper incisor teeth caused by 2 supernumerary teeth in the premaxilla, is reported. What is interesting about this case is that after the surgical removal of the supernumerary teeth, with a radiographic examination taken 6 months later, 2 other supernumerary teeth were observed. The authors point out that while the clinical approach can be the same for different situations it is not possible to have the same approach for the surgical therapy which may be different from case to case.
