Determination of height
The calculation of height on the basis of the dimensions of the teeth involves the proportionality
of the teeth to the height of the individual, comparing dental measurements with those of the
skeletal remains. One of the methods used is that proposed by Dr. Ubaldo Carrea, who proved
that the sum in millimetres of the mesiodistal distances of a central incisor, a lateral incisor
and a canine in the lower arch constitutes an arc of circumference whose chord is the central
measurement of the dental diagram, which the author called “lower radial chord”.
That is why human height is considered to lie between two measurements, the maximum
proportional to the arch and the minimum to the radial chord. (ix)
The mathematical formula used is as follows:
Maximum height (cm) = (arc x 6 x 10 x 3.1416)/2
Minimum height (cm) = (radial chord x 6 x 10 x 3.1416)/2
Radial chord = arc x 0.954
Men are closer to the maximum height while women are closer to the minimum.
C. Palatine folds
The palatine folds, or rugae, are ridges in the mucosa of the hard palate, immediately behind the
antero-superior teeth on both sides of the midline.
Numbering between three and five, they adopt a different and unique position in each
individual, even in identical twins. From the moment of their development in the third week of
intrauterine life they are permanent and unchanging throughout life. Even if altered by injury,
they regenerate according to their original pattern.

Their value in identification, given their permanence, invariability and uniqueness and because
they are protected from external damage, decomposition and incineration, is recognised and
accepted. As with fingerprints, comparison with a specimen allows an individual’s identity to
be obtained. (x)
Due to the different positions they adopt, as well as their size, shape and number, they are easily
classified, and there are a number of classifications by different authors.
The study of the palatine folds is called rugoscopy. The study of the entire palate (median
raphe, incisive papilla and palatine rugae) is called palatoscopy.
