Multiple Dental Inclusion in Monozygotic Twins with Congenital Visual Impairment

Table 3

L. P. twin dental formulae (semi-inclusion). Monozygotic twin L. P.’s dental formula as in ISO (International Organization for Standardization) 5 with the mesiodistal (MD) crown diameters of permanent teeth (in mm to the nearest 0.5 mm). Bold numbers report the mesiodistal dimension of a deciduous tooth, and italic numbers report the mesiodistal dimension of an unerupted tooth, evaluated on the panorex and calculated based on the magnification coefficient.
