Molariform Mesiodens in Primary Dentition: A Case Report

Cone-beam computed tomography exploration and surgical management of palatal, inverted, and impacted mesiodens

“…Supernumerary teeth or hyperdontia can be defined as teeth that exceed the normal dental complement, regardless of their locations and morphologies. [ 10 ] It is more common in the central region of the upper or lower jaw; however, its occurrence in the mandible is rare. [ 11 ] Mesiodens is the most common type of supernumerary teeth and is located in the midline between the two upper central incisors.…”

“…Although the abundant information is available on normal tooth development, the genetic etiology and molecular mechanisms that lead to congenital deviations in tooth number have not been clearly understood. [ 10 ] The literature reports three theories concerning the cause of mesiodentes, but this subject remains controversial. [ 15 ] The first one was a phylogenetic relic of extinct ancestors who had three central incisors known as phylogenetic reversion (atavism).…”

“…[ 15 ] The first one was a phylogenetic relic of extinct ancestors who had three central incisors known as phylogenetic reversion (atavism). [ 10 15 16 ] The second theory known as dichotomy suggests that the tooth bud is split to create two teeth, one of which is the mesiodens. [ 15 16 ] The third theory involving hyperactivity of dental lamina which was the most widely supported.…”

Bilateral Molariform Supernumerary Teeth in the Anterior Maxilla: A Report of Two Cases

“…They are most commonly found in the maxillary midline and occur twice as much in males than in females. Supernumerary teeth can be classified according to their form and locations ( 2 ).…”
