Monozygotic (MZ) twins, known as identical twins, originate from the same fertilized ovum, and by the virtue of which share the same DNA, placenta, amniotic fluid, and physical features. Dizygotic (DZ) twins are formed when two sperms fertilize two eggs separately, and they do not share the same DNA. Palatal rugae have been considered equivalent to fingerprints, as they are unique to each individual. Exploring the degree of resemblance in tooth morphometry and the pattern of rugae and various mandibular measurements on orthopantograph (OPG) among twins shall aid in forensic identification.
