Two-dimensional craniometry: morphometry and cephalometry
Over the last twenty years, bone research has raised interest; the function, shape and alterations of bone tissue have been analyzed and reported. Craniometry is a method developed as a tool for the precise measurement of the skull and facial structures and it has been used not only for humans, but for a variety of mammals. Morphometry is used to study and quantitatively compare the shape variation of biological objects, organs and organisms. Cephalometry uses two-dimensional measurements of the head and face involving a radiographic analysis to provide data on soft tissue, dental and skeletal relationships. Papers regarding bone research are difficult to access and usually, morphometry and cephalometry are reported separately. The object of this article is to report a two-dimensional craniometry performed in rats, using both techniques. This specific craniometry is a functional, well-established method which involves the entire anatomical aspects of the skull.

Both morphometry and cephalometry were used to establish a protocol for a two-step craniometry in Wistar rat dry skull, to evaluate the entire craniofacial complex.
