Management of unilateral non-syndromic concomitant hypodontia and supernumerary teeth in the mandibular molar region: a rare case report

Concomitant hypo-hyperodontia (CHH) is a rare condition that presents with the simultaneous occurrence of hypodontia and supernumerary teeth in the same individual. Even though the exact cause of its occurrence is not known, the combination of two opposite developmental disorders appearing together is mainly attributable to a genetic and environmental cause. In the general population, CHH is rare, and very few cases are published in the literature. This case report hereby presents an incidental finding of a missing mandibular first molar and an atypical unilateral supernumerary parapremolar in a 30-year-old male patient.
