Hemisection of fused teeth involving a maxillary permanent incisor and a supernumerary tooth

PurposeFusion is the union of adjacent teeth with or without pulp involvement. It can lead to serious esthetic problems and malocclusion. Here we report two rare cases of fusion of a permanent maxillary incisor with a supernumerary tooth that we successfully corrected using hemisection, which was performed after we confirmed that the roots had developed and separated.Case reportsIn the first case, the whole vital pulp was preserved. In the second case, partial pulpotomy was performed.ConclusionThe differential diagnosis and appropriate management of permanent anterior fused teeth are essential to attain a favorable outcome and minimize the risk of any complications.
