Resumo

Two monozygotic twin sisters presented to the Surgery clinic after referral, each for extraction ofan impacted tooth. Clinical examination revealed that one twin presented the mandibular left secondpremolar impacted, whereas the other had the mandibular left canine impacted. The literaturedemonstrates that alterations in tooth development may manifest in either of two ways in thecontext of this type of twinning. The first manifestation occurs when the characteristics are similar,yet on opposite sides; in this case, it is called “mirror imaging”. The second manifestation is theexpression of a certain characteristic identically in both, called “duplicates”. Manifestation of thesetwo types is directly related to the period of formation of the twins and consequently withchorionicity. This case presents a significant departure from the patterns previously described,suggesting that the actions of unknown local or environmental factors were able to alter the patternsof expression of this characteristic.
