چکیده: (1804 مشاهده) |
The present report aimed to study an uncommon case of a pair of twins that presented a discordant
dental phenotype. Family investigation, clinical, radiographic examination and molecular analysis were
performed in both girls. Molecular analysis confirmed the monozygosity by deoxyribonucleic acid
chip technology. One twin presented tooth agenesis in left upper lateral incisor and peg-shaped
on the contra lateral side while the other twin had no dental alterations. The dental casts study
employed digital caliper to compare morphological dimensions and showed alteration only in
peg-shaped tooth. In conclusion, this study provide support that one or more mutated gene could
cause discordances in dental phenotype in these monozygotic twins.
